-# C Thread Pool
-
-This is a minimal but advanced threadpool implementation.
-
-  * ANCI C and POSIX compliant
-  * Pause/resume/wait as you like
-  * Simple easy-to-digest API
-  * Well tested
-
-The threadpool is under MIT license. Notice that this project took a considerable amount of work and sacrifice of my free time and the reason I give it for free (even for commercial use) is so when you become rich and wealthy you don't forget about us open-source creatures of the night. Cheers!
-
-If this project reduced your development time feel free to buy me a coffee.

-
-
-## Run an example
-
-The library is not precompiled so you have to compile it with your project. The thread pool
-uses POSIX threads so if you compile with gcc on Linux you have to use the flag `-pthread` like this:
-
-    gcc example.c thpool.c -D THPOOL_DEBUG -pthread -o example
-
-
-Then run the executable like this:
-
-    ./example
-
-
-## Basic usage
-
-1. Include the header in your source file: `#include "thpool.h"`
-2. Create a thread pool with number of threads you want: `threadpool thpool = thpool_init(4);`
-3. Add work to the pool: `thpool_add_work(thpool, (void*)function_p, (void*)arg_p);`
-
-The workers(threads) will start their work automatically as fast as there is new work
-in the pool. If you want to wait for all added work to be finished before continuing
-you can use `thpool_wait(thpool);`. If you want to destroy the pool you can use
-`thpool_destroy(thpool);`.
-
-
-## API
-
-For a deeper look into the documentation check in the [thpool.h](https://github.com/Pithikos/C-Thread-Pool/blob/master/thpool.h) file. Below is a fast practical overview.
-
-| Function example                | Description                                                         |
-|---------------------------------|---------------------------------------------------------------------|
-| ***thpool_init(4)***            | Will return a new threadpool with `4` threads.                        |
-| ***thpool_add_work(thpool, (void*)function_p, (void*)arg_p)*** | Will add new work to the pool. Work is simply a function. You can pass a single argument to the function if you wish. If not, `NULL` should be passed. |
-| ***thpool_wait(thpool)***       | Will wait for all jobs (both in queue and currently running) to finish. |
-| ***thpool_destroy(thpool)***    | This will destroy the threadpool. If jobs are currently being executed, then it will wait for them to finish. |
-| ***thpool_pause(thpool)***      | All threads in the threadpool will pause no matter if they are idle or executing work. |
-| ***thpool_resume(thpool)***      | If the threadpool is paused, then all threads will resume from where they were.   |
-| ***thpool_num_threads_working(thpool)***  | Will return the number of currently working threads.   |
-
-
-## Contribution
-
-You are very welcome to contribute. If you have a new feature in mind, you can always open an issue on github describing it so you don't end up doing a lot of work that might not be eventually merged. Generally we are very open to contributions as long as they follow the below keypoints.
-
-* Try to keep the API as minimal as possible. That means if a feature or fix can be implemented without affecting the existing API but requires more development time, then we will opt to sacrifice development time.
-* Solutions need to be POSIX compliant. The thread-pool is advertised as such so it makes sense that it actually is.
-* For coding style simply try to stick to the conventions you find in the existing codebase.
-* Tests: A new fix or feature should be covered by tests. If the existing tests are not sufficient, we expect an according test to follow with the pull request.
-* Documentation: for a new feature please add documentation. For an API change the documentation has to be thorough and super easy to understand.

+## Debugging Segmentation Faults With Static Builds
+
+1. Download the debug version of the FrankenPHP binary from GitHub or create your custom static build including debug symbols:
+
+   ```console
+   docker buildx bake \
+       --load \
+       --set static-builder.args.DEBUG_SYMBOLS=1 \
+       --set "static-builder.platform=linux/amd64" \
+       static-builder
+   docker cp $(docker create --name static-builder-musl dunglas/frankenphp:static-builder-musl):/go/src/app/dist/frankenphp-linux-$(uname -m) frankenphp
+   ```
+
+2. Replace your current version of `frankenphp` by the debug FrankenPHP executable
+3. Start FrankenPHP as usual (alternatively, you can directly start FrankenPHP with GDB: `gdb --args frankenphp run`)
+4. Attach to the process with GDB:
+
+   ```console
+   gdb -p `pidof frankenphp`
+   ```
+
+5. If necessary, type `continue` in the GDB shell
+6. Make FrankenPHP crash
+7. Type `bt` in the GDB shell
+8. Copy the output
+
 ## Debugging Segmentation Faults in GitHub Actions
 
 1. Open `.github/workflows/tests.yml`
 2. Enable PHP debug symbols
 
-    ```patch
-        - uses: shivammathur/setup-php@v2
-          # ...
-          env:
-            phpts: ts
-    +       debug: true
-    ```
+   ```patch
+       - uses: shivammathur/setup-php@v2
+         # ...
+         env:
+           phpts: ts
+   +       debug: true
+   ```
 
 3. Enable `tmate` to connect to the container
 
-    ```patch
-        -
-          name: Set CGO flags
-          run: echo "CGO_CFLAGS=$(php-config --includes)" >> "$GITHUB_ENV"
-    +   -
-    +     run: |
-    +       sudo apt install gdb
-    +       mkdir -p /home/runner/.config/gdb/
-    +       printf "set auto-load safe-path /\nhandle SIG34 nostop noprint pass" > /home/runner/.config/gdb/gdbinit
-    +   -
-    +     uses: mxschmitt/action-tmate@v3
-    ```
+   ```patch
+       - name: Set CGO flags
+         run: echo "CGO_CFLAGS=$(php-config --includes)" >> "$GITHUB_ENV"
+   +   - run: |
+   +       sudo apt install gdb
+   +       mkdir -p /home/runner/.config/gdb/
+   +       printf "set auto-load safe-path /\nhandle SIG34 nostop noprint pass" > /home/runner/.config/gdb/gdbinit
+   +   - uses: mxschmitt/action-tmate@v3
+   ```
 
 4. Connect to the container
 5. Open `frankenphp.go`
 6. Enable `cgosymbolizer`
 
-    ```patch
-    -	//_ "github.com/ianlancetaylor/cgosymbolizer"
-    +	_ "github.com/ianlancetaylor/cgosymbolizer"
-    ```
+   ```patch
+   -	//_ "github.com/ianlancetaylor/cgosymbolizer"
+   +	_ "github.com/ianlancetaylor/cgosymbolizer"
+   ```
 
 7. Download the module: `go get`
 8. In the container, you can use GDB and the like:
 
-    ```console
-    go test -c -ldflags=-w
-    gdb --args ./frankenphp.test -test.run ^MyTest$
-    ```
+   ```console
+   go test -tags watcher -c -ldflags=-w
+   gdb --args frankenphp.test -test.run ^MyTest$
+   ```
 
 9. When the bug is fixed, revert all these changes

+## Translating the Documentation
+
+To translate the documentation and the site in a new language,
+follow these steps:
+
+1. Create a new directory named with the language's 2-character ISO code in this repository's `docs/` directory
+2. Copy all the `.md` files in the root of the `docs/` directory into the new directory (always use the English version as source for translation, as it's always up to date)
+3. Copy the `README.md` and `CONTRIBUTING.md` files from the root directory to the new directory
+4. Translate the content of the files, but don't change the filenames, also don't translate strings starting with `> [!` (it's special markup for GitHub)
+5. Create a Pull Request with the translations
+6. In the [site repository](https://github.com/dunglas/frankenphp-website/tree/main), copy and translate the translation files in the `content/`, `data/` and `i18n/` directories
+7. Translate the values in the created YAML file
+8. Open a Pull Request on the site repository

+# Using Classic Mode
+
+Without any additional configuration, FrankenPHP operates in classic mode. In this mode, FrankenPHP functions like a traditional PHP server, directly serving PHP files. This makes it a seamless drop-in replacement for PHP-FPM or Apache with mod_php.
+
+Similar to Caddy, FrankenPHP accepts an unlimited number of connections and uses a [fixed number of threads](config.md#caddyfile-config) to serve them. The number of accepted and queued connections is limited only by the available system resources.
+The PHP thread pool operates with a fixed number of threads initialized at startup, comparable to the static mode of PHP-FPM. It's also possible to let threads [scale automatically at runtime](performance.md#max_threads), similar to the dynamic mode of PHP-FPM.
+
+Queued connections will wait indefinitely until a PHP thread is available to serve them. To avoid this, you can use the max_wait_time [configuration](config.md#caddyfile-config) in FrankenPHP's global configuration to limit the duration a request can wait for a free PHP thread before being rejected.
+Additionally, you can set a reasonable [write timeout in Caddy](https://caddyserver.com/docs/caddyfile/options#timeouts).
+
+Each Caddy instance will only spin up one FrankenPHP thread pool, which will be shared across all `php_server` blocks.

+   ```
+
+2. 将当前版本的 `frankenphp` 替换为 debug FrankenPHP 可执行文件
+3. 照常启动 FrankenPHP（或者，你可以直接使用 GDB 启动 FrankenPHP： `gdb --args frankenphp run`）
+4. 使用 GDB 附加到进程：
+
+   ```console
+   gdb -p `pidof frankenphp`
+   ```
+
+5. 如有必要，请在 GDB shell 中输入 `continue`
+6. 使 FrankenPHP 崩溃
+7. 在 GDB shell 中输入 `bt`
+8. 复制输出
+
+## 在 GitHub Actions 中调试分段错误
+
+1. 打开 `.github/workflows/tests.yml`
+2. 启用 PHP 调试符号
+
+   ```patch
+       - uses: shivammathur/setup-php@v2
+         # ...
+         env:
+           phpts: ts
+   +       debug: true
+   ```
+
+3. 启用 `tmate` 以连接到容器
+
+   ```patch

+   +   - uses: mxschmitt/action-tmate@v3
+   ```
+
+4. 连接到容器
+5. 打开 `frankenphp.go`
+6. 启用 `cgosymbolizer`
+
+   ```patch
+   -	//_ "github.com/ianlancetaylor/cgosymbolizer"
+   +	_ "github.com/ianlancetaylor/cgosymbolizer"
+   ```
+
+7. 下载模块： `go get`
+8. 在容器中，可以使用 GDB 和以下：
+
+   ```console

+# 使用经典模式
+
+在没有任何额外配置的情况下，FrankenPHP 以经典模式运行。在此模式下，FrankenPHP 的功能类似于传统的 PHP 服务器，直接提供 PHP 文件服务。这使其成为 PHP-FPM 或 Apache with mod_php 的无缝替代品。
+
+与 Caddy 类似，FrankenPHP 接受无限数量的连接，并使用[固定数量的线程](config.md#caddyfile-配置)来为它们提供服务。接受和排队的连接数量仅受可用系统资源的限制。
+PHP 线程池使用在启动时初始化的固定数量的线程运行，类似于 PHP-FPM 的静态模式。也可以让线程在[运行时自动扩展](performance.md#max_threads)，类似于 PHP-FPM 的动态模式。
+
+排队的连接将无限期等待，直到有 PHP 线程可以为它们提供服务。为了避免这种情况，你可以在 FrankenPHP 的全局配置中使用 max_wait_time [配置](config.md#caddyfile-配置)来限制请求可以等待空闲的 PHP 线程的时间，超时后将被拒绝。
+此外，你还可以在 Caddy 中设置合理的[写超时](https://caddyserver.com/docs/caddyfile/options#timeouts)。
+
+每个 Caddy 实例只会启动一个 FrankenPHP 线程池，该线程池将在所有 `php_server` 块之间共享。

+# 从源代码编译
+
+本文档解释了如何创建一个 FrankenPHP 构建，它将 PHP 加载为一个动态库。
+这是推荐的方法。
+
+或者，你也可以 [编译静态版本](static.md)。
+
+## 安装 PHP
+
+FrankenPHP 支持 PHP 8.2 及更高版本。
+
+### 使用 Homebrew (Linux 和 Mac)
+
+安装与 FrankenPHP 兼容的 libphp 版本的最简单方法是使用 [Homebrew PHP](https://github.com/shivammathur/homebrew-php) 提供的 ZTS 包。
+
+首先，如果尚未安装，请安装 [Homebrew](https://brew.sh)。
+
+然后，安装 PHP 的 ZTS 变体、Brotli（可选，用于压缩支持）和 watcher（可选，用于文件更改检测）：
+
+```console
+brew install shivammathur/php/php-zts brotli watcher
+brew link --overwrite --force shivammathur/php/php-zts
+```
+
+### 通过编译 PHP
+
+或者，你可以按照以下步骤，使用 FrankenPHP 所需的选项从源代码编译 PHP。
+
+首先，[获取 PHP 源代码](https://www.php.net/downloads.php) 并提取它们：
+
+```console
+tar xf php-*
+cd php-*/
+```
+
+然后，运行适用于你平台的 `configure` 脚本。
+以下 `./configure` 标志是必需的，但你可以添加其他标志，例如编译扩展或附加功能。
+
+#### Linux
+
+```console
+./configure \
+    --enable-embed \
+    --enable-zts \
+    --disable-zend-signals \
+    --enable-zend-max-execution-timers
+```
+
+#### Mac
+
+使用 [Homebrew](https://brew.sh/) 包管理器安装所需的和可选的依赖项：
+
+```console
+brew install libiconv bison brotli re2c pkg-config watcher
+echo 'export PATH="/opt/homebrew/opt/bison/bin:$PATH"' >> ~/.zshrc
+```
+
+然后运行 `./configure` 脚本：
+
+```console
+./configure \
+    --enable-embed \
+    --enable-zts \
+    --disable-zend-signals \
+    --with-iconv=/opt/homebrew/opt/libiconv/
+```
+
+#### 编译 PHP
+
+最后，编译并安装 PHP：
+
+```console
+make -j"$(getconf _NPROCESSORS_ONLN)"
+sudo make install
+```
+
+## 安装可选依赖项
+
+某些 FrankenPHP 功能依赖于必须安装的可选系统依赖项。

+
+### 使用 xcaddy
+
+推荐的方法是使用 [xcaddy](https://github.com/caddyserver/xcaddy) 来编译 FrankenPHP。
+`xcaddy` 还允许轻松添加 [自定义 Caddy 模块](https://caddyserver.com/docs/modules/) 和 FrankenPHP 扩展：
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/dunglas/frankenphp/caddy \
+    --with github.com/dunglas/mercure/caddy \
+    --with github.com/dunglas/vulcain/caddy
+    # 在这里添加额外的 Caddy 模块和 FrankenPHP 扩展
+```
+
+> [!TIP]
+>
+> 如果你的系统基于 musl libc（Alpine Linux 上默认使用）并搭配 Symfony 使用，
+> 你可能需要增加默认堆栈大小。
+> 否则，你可能会收到如下错误 `PHP Fatal error: Maximum call stack size of 83360 bytes reached during compilation. Try splitting expression`
+>
+> 请将 `XCADDY_GO_BUILD_FLAGS` 环境变量更改为如下类似的值
+> `XCADDY_GO_BUILD_FLAGS=$'-ldflags "-w -s -extldflags \'-Wl,-z,stack-size=0x80000\'"'`
+> （根据你的应用需求更改堆栈大小）。
+
+### 不使用 xcaddy
+
+或者，可以通过直接使用 `go` 命令来编译 FrankenPHP 而不使用 `xcaddy`：
+
+```console
+curl -L https://github.com/php/frankenphp/archive/refs/heads/main.tar.gz | tar xz
+cd frankenphp-main/caddy/frankenphp
+CGO_CFLAGS=$(php-config --includes) CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" go build -tags=nobadger,nomysql,nopgx

+# 配置
+
+FrankenPHP、Caddy 以及 Mercure 和 Vulcain 模块可以使用 [Caddy 支持的格式](https://caddyserver.com/docs/getting-started#your-first-config) 进行配置。
+
+在 [Docker 镜像](docker.md) 中，`Caddyfile` 位于 `/etc/frankenphp/Caddyfile`。
+静态二进制文件也会在执行 `frankenphp run` 命令的目录中查找 `Caddyfile`。
+你可以使用 `-c` 或 `--config` 选项指定自定义路径。
+
+PHP 本身可以[使用 `php.ini` 文件](https://www.php.net/manual/zh/configuration.file.php)进行配置。
+
+根据你的安装方法，PHP 解释器将在上述位置查找配置文件。
+
+## Docker
+
+- `php.ini`: `/usr/local/etc/php/php.ini`（默认情况下不提供 `php.ini`）
+- 附加配置文件: `/usr/local/etc/php/conf.d/*.ini`
+- PHP 扩展: `/usr/local/lib/php/extensions/no-debug-zts-<YYYYMMDD>/`
+- 你应该复制 PHP 项目提供的官方模板：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# 生产环境:
+RUN cp $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini
+
+# 或开发环境:
+RUN cp $PHP_INI_DIR/php.ini-development $PHP_INI_DIR/php.ini
+```
+
+## RPM 和 Debian 包
+
+- `php.ini`: `/etc/frankenphp/php.ini`（默认情况下提供带有生产预设的 `php.ini` 文件）
+- 附加配置文件: `/etc/frankenphp/php.d/*.ini`
+- PHP 扩展: `/usr/lib/frankenphp/modules/`
+
+## 静态二进制文件
+
+- `php.ini`: 执行 `frankenphp run` 或 `frankenphp php-server` 的目录，然后是 `/etc/frankenphp/php.ini`
+- 附加配置文件: `/etc/frankenphp/php.d/*.ini`
+- PHP 扩展: 无法加载，将它们打包在二进制文件本身中
+- 复制 [PHP 源代码](https://github.com/php/php-src/) 中提供的 `php.ini-production` 或 `php.ini-development` 中的一个。
+
+## Caddyfile 配置
+
+可以在站点块中使用 `php_server` 或 `php` [HTTP 指令](https://caddyserver.com/docs/caddyfile/concepts#directives) 来为你的 PHP 应用程序提供服务。
+
+最小示例：
+
+```caddyfile
+localhost {
+	# 启用压缩（可选）
+	encode zstd br gzip
+	# 在当前目录中执行 PHP 文件并提供资源服务
+	php_server
+}
+```
+
+你还可以使用全局选项显式配置 FrankenPHP:
+`frankenphp` [全局选项](https://caddyserver.com/docs/caddyfile/concepts#global-options) 可用于配置 FrankenPHP。
+
+```caddyfile
+{
+	frankenphp {
+		num_threads <num_threads> # 设置要启动的 PHP 线程数量。默认：可用 CPU 数量的 2 倍。
+		max_threads <max_threads> # 限制可以在运行时启动的额外 PHP 线程的数量。默认值：num_threads。可以设置为 'auto'。
+		max_wait_time <duration> # 设置请求在超时之前可以等待的最大时间，直到找到一个空闲的 PHP 线程。 默认：禁用。
+		php_ini <key> <value> # 设置一个 php.ini 指令。可以多次使用以设置多个指令。
+		worker {
+			file <path> # 设置工作脚本的路径。
+			num <num> # 设置要启动的 PHP 线程数量，默认为可用 CPU 数量的 2 倍。
+			env <key> <value> # 设置一个额外的环境变量为给定的值。可以多次指定以设置多个环境变量。
+			watch <path> # 设置要监视文件更改的路径。可以为多个路径多次指定。
+			name <name> # 设置worker的名称，用于日志和指标。默认值：worker文件的绝对路径。
+			max_consecutive_failures <num> # 设置在工人被视为不健康之前的最大连续失败次数，-1意味着工人将始终重新启动。默认值：6。
+		}
+	}
+}
+
+# ...
+```
+
+或者，您可以使用 `worker` 选项的一行简短形式。
+
+```caddyfile
+{
+	frankenphp {
+		worker <file> <num>
+	}
+}
+
+# ...
+```
+
+如果您在同一服务器上服务多个应用程序，您还可以定义多个工作线程:
+
+```caddyfile
+app.example.com {
+    root /path/to/app/public
+	php_server {
+		root /path/to/app/public # 允许更好的缓存
+		worker index.php <num>
+	}
+}
+
+other.example.com {
+    root /path/to/other/public
+	php_server {
+		root /path/to/other/public
+		worker index.php <num>
+	}
+}
+
+# ...
+```
+
+使用 `php_server` 指令通常是您需要的。
+但是如果你需要完全控制，你可以使用更低级的 `php` 指令。
+`php` 指令将所有输入传递给 PHP，而不是先检查是否
+是一个PHP文件。在[性能页面](performance.md#try_files)中了解更多关于它的信息。
+
+使用 `php_server` 指令等同于以下配置:
+
+```caddyfile
+route {
+	# 为目录请求添加尾斜杠
+	@canonicalPath {
+		file {path}/index.php
+		not path */
+	}
+	redir @canonicalPath {path}/ 308
+	# 如果请求的文件不存在，则尝试 index 文件
+	@indexFiles file {
+		try_files {path} {path}/index.php index.php
+		split_path .php
+	}
+	rewrite @indexFiles {http.matchers.file.relative}
+	# FrankenPHP!
+	@phpFiles path *.php
+	php @phpFiles
+	file_server
+}
+```
+
+`php_server` 和 `php` 指令有以下选项：
+
+```caddyfile
+php_server [<matcher>] {
+	root <directory> # 将根文件夹设置为站点。默认值：`root` 指令。
+	split_path <delim...> # 设置用于将 URI 分割成两部分的子字符串。第一个匹配的子字符串将用来将 "路径信息" 与路径分开。第一部分后缀为匹配的子字符串，并将被视为实际资源（CGI 脚本）名称。第二部分将被设置为脚本使用的 PATH_INFO。默认值：`.php`。
+	resolve_root_symlink false # 禁用通过评估符号链接（如果存在）将 `root` 目录解析为其实际值（默认启用）。
+	env <key> <value> # 设置一个额外的环境变量为给定的值。可以多次指定以设置多个环境变量。
+	file_server off # 禁用内置的 file_server 指令。
+	worker { # 为此服务器创建特定的worker。可以多次指定以创建多个workers。
+		file <path> # 设置工作脚本的路径，可以相对于 php_server 根目录
+		num <num> # 设置要启动的 PHP 线程数，默认为可用数量的 2 倍
+		name <name> # 为worker设置名称，用于日志和指标。默认值：worker文件的绝对路径。定义在 php_server 块中时，始终以 m# 开头。
+		watch <path> # 设置要监视文件更改的路径。可以为多个路径多次指定。
+		env <key> <value> # 设置一个额外的环境变量为给定值。可以多次指定以设置多个环境变量。此工作进程的环境变量也从 php_server 父进程继承，但可以在此处覆盖。
+		match <path> # 将worker匹配到路径模式。覆盖 try_files，并且只能在 php_server 指令中使用。
+	}
+	worker <other_file> <num> # 也可以像在全局 frankenphp 块中那样使用简短形式。
+}
+```
+
+### 监控文件变化
+
+由于 workers 只会启动您的应用程序一次并将其保留在内存中，
+因此对您的 PHP 文件的任何更改不会立即反映出来。
+
+Wworkers 可以通过 `watch` 指令在文件更改时重新启动。
+这对开发环境很有用。
+
+```caddyfile
+{
+	frankenphp {
+		worker {
+			file  /path/to/app/public/worker.php
+			watch
+		}
+	}
+}
+```
+
+如果没有指定 `watch` 目录，它将回退到 `./**/*.{php,yaml,yml,twig,env}`，
+这将监视启动 FrankenPHP 进程的目录及其子目录中的所有 `.php`、`.yaml`、`.yml`、`.twig` 和 `.env` 文件。
+你也可以通过 [shell 文件名模式](https://pkg.go.dev/path/filepath#Match) 指定一个或多个目录：
+
+```caddyfile
+{
+	frankenphp {
+		worker {
+			file  /path/to/app/public/worker.php
+			watch /path/to/app # 监视 /path/to/app 所有子目录中的所有文件
+			watch /path/to/app/*.php # 监视位于/path/to/app中的以.php结尾的文件
+			watch /path/to/app/**/*.php # 监视 /path/to/app 及子目录中的 PHP 文件
+			watch /path/to/app/**/*.{php,twig} # 在/path/to/app及其子目录中监视PHP和Twig文件
+		}
+	}
+}
+```
+
+- `**` 模式表示递归监视
+- 目录也可以是相对的（相对于FrankenPHP进程启动的位置）
+- 如果您定义了多个workers，当文件发生更改时，将重新启动所有workers。
+- 小心查看在运行时创建的文件（如日志），因为它们可能导致不必要的工作进程重启。
+
+文件监视器基于[e-dant/watcher](https://github.com/e-dant/watcher)。
+
+## 将 worker 匹配到一条路径
+
+在传统的PHP应用程序中，脚本总是放在公共目录中。
+这对于工作脚本也是如此，这些脚本被视为任何其他PHP脚本。
+如果您想将工作脚本放在公共目录外，可以通过 `match` 指令来实现。
+
+`match` 指令是 `try_files` 的一种优化替代方案，仅在 `php_server` 和 `php` 内部可用。
+以下示例将在公共目录中提供文件（如果存在）
+并将请求转发给与路径模式匹配的 worker。
+
+```caddyfile
+{
+	frankenphp {
+		php_server {
+			worker {
+				file /path/to/worker.php # 文件可以在公共路径之外
+				match /api/* # 所有以 /api/ 开头的请求将由此 worker 处理
+			}
+		}
+	}
+}
+```
+
+### 全双工 (HTTP/1)
+
+在使用HTTP/1.x时，可能希望启用全双工模式，以便在完整主体之前写入响应。
+已被阅读。(例如：WebSocket、服务器发送事件等。)
+
+这是一个可选配置，需要添加到 `Caddyfile` 中的全局选项中:
+
+```caddyfile
+{
+  servers {
+    enable_full_duplex
+  }
+}
+```
+
+> [!CAUTION]
+>
+> 启用此选项可能导致不支持全双工的旧HTTP/1.x客户端死锁。
+> 这也可以通过配置 `CADDY_GLOBAL_OPTIONS` 环境配置来实现:
+
+```sh
+CADDY_GLOBAL_OPTIONS="servers {
+  enable_full_duplex
+}"
+```
+
+您可以在[Caddy文档](https://caddyserver.com/docs/caddyfile/options#enable-full-duplex)中找到有关此设置的更多信息。
+
+## 环境变量
+
+可以使用以下环境变量在不修改 `Caddyfile` 的情况下注入 Caddy 指令：
+
+- `SERVER_NAME`: 更改[监听的地址](https://caddyserver.com/docs/caddyfile/concepts#addresses)，提供的宿主名也将用于生成的TLS证书。
+- `SERVER_ROOT`: 更改网站的根目录，默认为 `public/`
+- `CADDY_GLOBAL_OPTIONS`: 注入[全局选项](https://caddyserver.com/docs/caddyfile/options)
+- `FRANKENPHP_CONFIG`: 在 `frankenphp` 指令下注入配置
+
+至于 FPM 和 CLI SAPIs，环境变量默认在 `$_SERVER` 超全局中暴露。
+
+[the `variables_order` PHP 指令](https://www.php.net/manual/en/ini.core.php#ini.variables-order) 的 `S` 值始终等于 `ES`，无论 `E` 在该指令中的其他位置如何。
+
+## PHP 配置
+
+加载[附加的 PHP 配置文件](https://www.php.net/manual/en/configuration.file.php#configuration.file.scan)，
+`PHP_INI_SCAN_DIR`环境变量可以被使用。
+设置后，PHP 将加载给定目录中所有带有 `.ini` 扩展名的文件。
+
+您还可以通过在 `Caddyfile` 中使用 `php_ini` 指令来更改 PHP 配置:
+
+```caddyfile
+{
+    frankenphp {
+        php_ini memory_limit 256M
+
+        # 或者
+
+        php_ini {
+            memory_limit 256M
+            max_execution_time 15
+        }
+    }
+}
+```
+
+## 启用调试模式
+
+使用Docker镜像时，将`CADDY_GLOBAL_OPTIONS`环境变量设置为`debug`以启用调试模式:
+
+```console
+docker run -v $PWD:/app/public \
+    -e CADDY_GLOBAL_OPTIONS=debug \
+    -p 80:80 -p 443:443 -p 443:443/udp \

+# 构建自定义 Docker 镜像
+
+[FrankenPHP Docker 镜像](https://hub.docker.com/r/dunglas/frankenphp) 基于 [官方 PHP 镜像](https://hub.docker.com/_/php/)。提供适用于流行架构的 Debian 和 Alpine Linux 变体。推荐使用 Debian 变体。
+
+提供 PHP 8.2、8.3、8.4 和 8.5 的变体。
+
+标签遵循此模式：`dunglas/frankenphp:<frankenphp-version>-php<php-version>-<os>`
+
+- `<frankenphp-version>` 和 `<php-version>` 分别是 FrankenPHP 和 PHP 的版本号，范围从主版本（例如 `1`）、次版本（例如 `1.2`）到补丁版本（例如 `1.2.3`）。
+- `<os>` 要么是 `bookworm`（用于 Debian Bookworm）要么是 `alpine`（用于 Alpine 的最新稳定版本）。
+
+[浏览标签](https://hub.docker.com/r/dunglas/frankenphp/tags)。
+
+## 如何使用镜像
+
+在项目中创建 `Dockerfile`：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+COPY . /app/public
+```
+
+然后运行以下命令以构建并运行 Docker 镜像：
+
+```console
+docker build -t my-php-app .
+docker run -it --rm --name my-running-app my-php-app
+```
+
+## 如何安装更多 PHP 扩展
+
+[`docker-php-extension-installer`](https://github.com/mlocati/docker-php-extension-installer) 脚本在基础镜像中提供。
+添加额外的 PHP 扩展很简单：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# 在此处添加其他扩展：
+RUN install-php-extensions \
+	pdo_mysql \
+	gd \
+	intl \
+	zip \
+	opcache
+```
+
+## 如何安装更多 Caddy 模块
+
+FrankenPHP 建立在 Caddy 之上，所有 [Caddy 模块](https://caddyserver.com/docs/modules/) 都可以与 FrankenPHP 一起使用。
+
+安装自定义 Caddy 模块的最简单方法是使用 [xcaddy](https://github.com/caddyserver/xcaddy)：
+
+```dockerfile
+FROM dunglas/frankenphp:builder AS builder
+
+# 在构建器镜像中复制 xcaddy
+COPY --from=caddy:builder /usr/bin/xcaddy /usr/bin/xcaddy
+
+# 必须启用 CGO 才能构建 FrankenPHP
+RUN CGO_ENABLED=1 \
+    XCADDY_SETCAP=1 \
+    XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+    CGO_CFLAGS=$(php-config --includes) \
+    CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+    xcaddy build \
+        --output /usr/local/bin/frankenphp \
+        --with github.com/dunglas/frankenphp=./ \
+        --with github.com/dunglas/frankenphp/caddy=./caddy/ \
+        --with github.com/dunglas/caddy-cbrotli \
+        # Mercure 和 Vulcain 包含在官方版本中，如果不需要你可以删除它们
+        --with github.com/dunglas/mercure/caddy \
+        --with github.com/dunglas/vulcain/caddy
+        # 在此处添加额外的 Caddy 模块
+
+FROM dunglas/frankenphp AS runner
+
+# 将官方二进制文件替换为包含自定义模块的二进制文件
+COPY --from=builder /usr/local/bin/frankenphp /usr/local/bin/frankenphp
+```
+
+FrankenPHP 提供的 `builder` 镜像包含 `libphp` 的编译版本。
+[用于构建的镜像](https://hub.docker.com/r/dunglas/frankenphp/tags?name=builder) 适用于所有版本的 FrankenPHP 和 PHP，包括 Alpine 和 Debian。
+
+> [!TIP]
+>
+> 如果你的系统基于 musl libc（Alpine Linux 上默认使用）并搭配 Symfony 使用，
+> 你可能需要 [增加默认堆栈大小](compile.md#using-xcaddy)。
+
+## 默认启用 worker 模式
+
+设置 `FRANKENPHP_CONFIG` 环境变量以使用 worker 脚本启动 FrankenPHP：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# ...
+
+ENV FRANKENPHP_CONFIG="worker ./public/index.php"
+```
+
+## 开发挂载宿主机目录
+
+要使用 FrankenPHP 轻松开发，请从包含应用程序源代码的主机挂载目录作为 Docker 容器中的 volume：
+
+```console
+docker run -v $PWD:/app/public -p 80:80 -p 443:443 -p 443:443/udp --tty my-php-app
+```
+
+> [!TIP]
+>
+> `--tty` 选项允许使用清晰可读的日志，而不是 JSON 日志。
+
+使用 Docker Compose：
+
+```yaml
+# compose.yaml
+
+services:
+  php:
+    image: dunglas/frankenphp
+    # 如果要使用自定义 Dockerfile，请取消注释以下行
+    #build: .
+    # 如果要在生产环境中运行，请取消注释以下行
+    # restart: always
+    ports:
+      - "80:80" # HTTP
+      - "443:443" # HTTPS
+      - "443:443/udp" # HTTP/3
+    volumes:
+      - ./:/app/public
+      - caddy_data:/data
+      - caddy_config:/config
+    # 在生产环境中注释以下行，它允许在 dev 中使用清晰可读日志
+    tty: true
+
+# Caddy 证书和配置所需的挂载目录
+volumes:
+  caddy_data:
+  caddy_config:
+```
+
+## 以非 root 用户身份运行
+
+FrankenPHP 可以在 Docker 中以非 root 用户身份运行。
+
+下面是一个示例 `Dockerfile`：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+ARG USER=appuser
+
+RUN \
+	# 在基于 alpine 的发行版使用 "adduser -D ${USER}"
+	useradd ${USER}; \
+	# 需要开放80和443端口的权限
+	setcap CAP_NET_BIND_SERVICE=+eip /usr/local/bin/frankenphp; \
+	# 需要 /config/caddy 和 /data/caddy 目录的写入权限
+	chown -R ${USER}:${USER} /config/caddy /data/caddy
+
+USER ${USER}
+```
+
+### 无权限运行
+
+即使在无根运行时，FrankenPHP 也需要 `CAP_NET_BIND_SERVICE` 权限来将
+Web 服务器绑定到特权端口（80 和 443）。
+
+如果你在非特权端口（1024 及以上）上公开 FrankenPHP，则可以以非 root 用户身份运行
+Web 服务器，并且不需要任何权限：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+ARG USER=appuser
+
+RUN \
+	# 在基于 alpine 的发行版使用 "adduser -D ${USER}"
+	useradd ${USER}; \
+	# 移除默认权限
+	setcap -r /usr/local/bin/frankenphp; \
+	# 给予 /config/caddy 和 /data/caddy 写入权限
+	chown -R ${USER}:${USER} /config/caddy /data/caddy
+
+USER ${USER}
+```
+
+接下来，设置 `SERVER_NAME` 环境变量以使用非特权端口。
+示例：`:8000`
+
+## 更新
+
+Docker 镜像会按照以下条件更新：
+
+- 发布新的版本后
+- 每日 4:00（UTC 时间）检查新的 PHP 镜像
+
+## 开发版本
+
+可在此 [`dunglas/frankenphp-dev`](https://hub.docker.com/repository/docker/dunglas/frankenphp-dev) 仓库获取开发版本。
+每次在 GitHub 仓库的主分支有新的 commit 都会触发一次新的 build。

+# PHP 应用程序作为独立二进制文件
+
+FrankenPHP 能够将 PHP 应用程序的源代码和资源文件嵌入到静态的、独立的二进制文件中。
+
+由于这个特性，PHP 应用程序可以作为独立的二进制文件分发，包括应用程序本身、PHP 解释器和生产级 Web 服务器 Caddy。
+
+了解有关此功能的更多信息 [Kévin 在 SymfonyCon 上的演讲](https://dunglas.dev/2023/12/php-and-symfony-apps-as-standalone-binaries/)。
+
+有关嵌入 Laravel 应用程序，请[阅读此特定文档条目](laravel.md#laravel-apps-as-standalone-binaries)。
+
+## 准备你的应用
+
+在创建独立二进制文件之前，请确保应用已准备好进行打包。
+
+例如，你可能希望：
+
+- 给应用安装生产环境的依赖
+- 导出 autoloader
+- 如果可能，为应用启用生产模式
+- 丢弃不需要的文件，例如 `.git` 或测试文件，以减小最终二进制文件的大小
+
+例如，对于 Symfony 应用程序，你可以使用以下命令：
+
+```console
+# 导出项目以避免 .git/ 等目录
+mkdir $TMPDIR/my-prepared-app
+git archive HEAD | tar -x -C $TMPDIR/my-prepared-app
+cd $TMPDIR/my-prepared-app
+
+# 设置适当的环境变量
+echo APP_ENV=prod > .env.local
+echo APP_DEBUG=0 >> .env.local
+
+# 删除测试和其他不需要的文件以节省空间
+# 或者，将这些文件添加到您的 .gitattributes 文件中，并设置 export-ignore 属性
+rm -Rf tests/
+
+# 安装依赖项
+composer install --ignore-platform-reqs --no-dev -a
+
+# 优化 .env
+composer dump-env prod
+```
+
+### 自定义配置
+
+要自定义[配置](config.md)，您可以放置一个 `Caddyfile` 以及一个 `php.ini` 文件
+在应用程序的主目录中嵌入（在之前的示例中是`$TMPDIR/my-prepared-app`）。
+
+## 创建 Linux 二进制文件
+
+创建 Linux 二进制文件的最简单方法是使用我们提供的基于 Docker 的构建器。
+
+1. 在准备好的应用的存储库中创建一个名为 `static-build.Dockerfile` 的文件。

+```console
+./my-app php-server
+```
+
+如果你的应用包含 [worker 脚本](worker.md)，请使用如下命令启动 worker：
+
+```console
+./my-app php-server --worker public/index.php
+```
+
+要启用 HTTPS（自动创建 Let's Encrypt 证书）、HTTP/2 和 HTTP/3，请指定要使用的域名：

+
+你还可以运行二进制文件中嵌入的 PHP CLI 脚本：
+
+```console
+./my-app php-cli bin/console
+```
+
+## PHP Extensions
+
+默认情况下，脚本将构建您项目的 `composer.json` 文件中所需的扩展（如果有的话）。
+如果 `composer.json` 文件不存在，将构建默认扩展，如 [静态构建条目](static.md) 中所述。
+
+要自定义扩展，请使用 `PHP_EXTENSIONS` 环境变量。
+
+## 自定义构建
+
+[阅读静态构建文档](static.md) 查看如何自定义二进制文件（扩展、PHP 版本等）。
+
+## 分发二进制文件
+
+在Linux上，创建的二进制文件使用[UPX](https://upx.github.io)进行压缩。
+
+在Mac上，您可以在发送文件之前压缩它以减小文件大小。

+# 使用 Go 编写 PHP 扩展
+
+使用 FrankenPHP，你可以**使用 Go 编写 PHP 扩展**，这允许你创建**高性能的原生函数**，可以直接从 PHP 调用。你的应用程序可以利用任何现有或新的 Go 库，以及直接从你的 PHP 代码中使用**协程（goroutines）的并发模型**。
+
+编写 PHP 扩展通常使用 C 语言完成，但通过一些额外的工作，也可以使用其他语言编写。PHP 扩展允许你利用底层语言的强大功能来扩展 PHP 的功能，例如，通过添加原生函数或优化特定操作。
+
+借助 Caddy 模块，你可以使用 Go 编写 PHP 扩展，并将其快速集成到 FrankenPHP 中。
+
+## 两种方法
+
+FrankenPHP 提供两种方式来创建 Go 语言的 PHP 扩展：
+
+1. **使用扩展生成器** - 推荐的方法，为大多数用例生成所有必要的样板代码，让你专注于编写 Go 代码
+2. **手动实现** - 对于高级用例，完全控制扩展结构
+
+我们将从生成器方法开始，因为这是最简单的入门方式，然后为那些需要完全控制的人展示手动实现。
+
+## 使用扩展生成器
+
+FrankenPHP 捆绑了一个工具，允许你**仅使用 Go 创建 PHP 扩展**。**无需编写 C 代码**或直接使用 CGO：FrankenPHP 还包含一个**公共类型 API**，帮助你在 Go 中编写扩展，而无需担心**PHP/C 和 Go 之间的类型转换**。
+
+> [!TIP]
+> 如果你想了解如何从头开始在 Go 中编写扩展，可以阅读下面的手动实现部分，该部分演示了如何在不使用生成器的情况下在 Go 中编写 PHP 扩展。
+
+请记住，此工具**不是功能齐全的扩展生成器**。它旨在帮助你在 Go 中编写简单的扩展，但它不提供 PHP 扩展的最高级功能。如果你需要编写更**复杂和优化**的扩展，你可能需要编写一些 C 代码或直接使用 CGO。
+
+### 先决条件
+
+正如下面的手动实现部分所涵盖的，你需要[获取 PHP 源代码](https://www.php.net/downloads.php)并创建一个新的 Go 模块。
+
+#### 创建新模块并获取 PHP 源代码
+
+在 Go 中编写 PHP 扩展的第一步是创建一个新的 Go 模块。你可以使用以下命令：
+
+```console
+go mod init github.com/my-account/my-module
+```
+
+第二步是为后续步骤[获取 PHP 源代码](https://www.php.net/downloads.php)。获取后，将它们解压到你选择的目录中，不要放在你的 Go 模块内：
+
+```console
+tar xf php-*
+```
+
+### 编写扩展
+
+现在一切都设置好了，可以在 Go 中编写你的原生函数。创建一个名为 `stringext.go` 的新文件。我们的第一个函数将接受一个字符串作为参数，重复次数，一个布尔值来指示是否反转字符串，并返回结果字符串。这应该看起来像这样：
+
+```go
+import (
+    "C"
+    "github.com/dunglas/frankenphp"
+    "strings"
+)
+
+//export_php:function repeat_this(string $str, int $count, bool $reverse): string
+func repeat_this(s *C.zend_string, count int64, reverse bool) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    result := strings.Repeat(str, int(count))
+    if reverse {
+        runes := []rune(result)
+        for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
+            runes[i], runes[j] = runes[j], runes[i]
+        }
+        result = string(runes)
+    }
+
+    return frankenphp.PHPString(result, false)
+}
+```
+
+这里有两个重要的事情要注意：
+
+- 指令注释 `//export_php:function` 定义了 PHP 中的函数签名。这是生成器知道如何使用正确的参数和返回类型生成 PHP 函数的方式；
+- 函数必须返回 `unsafe.Pointer`。FrankenPHP 提供了一个 API 来帮助你在 C 和 Go 之间进行类型转换。
+
+虽然第一点不言自明，但第二点可能更难理解。让我们在下一节中深入了解类型转换。
+
+### 类型转换
+
+虽然一些变量类型在 C/PHP 和 Go 之间具有相同的内存表示，但某些类型需要更多逻辑才能直接使用。这可能是编写扩展时最困难的部分，因为它需要了解 Zend 引擎的内部结构以及变量在 PHP 中的内部存储方式。此表总结了你需要知道的内容：
+
+| PHP 类型           | Go 类型             | 直接转换 | C 到 Go 助手          | Go 到 C 助手           | 类方法支持 |
+| ------------------ | ------------------- | -------- | --------------------- | ---------------------- | ---------- |
+| `int`              | `int64`             | ✅       | -                     | -                      | ✅         |
+| `?int`             | `*int64`            | ✅       | -                     | -                      | ✅         |
+| `float`            | `float64`           | ✅       | -                     | -                      | ✅         |
+| `?float`           | `*float64`          | ✅       | -                     | -                      | ✅         |
+| `bool`             | `bool`              | ✅       | -                     | -                      | ✅         |
+| `?bool`            | `*bool`             | ✅       | -                     | -                      | ✅         |
+| `string`/`?string` | `*C.zend_string`    | ❌       | frankenphp.GoString() | frankenphp.PHPString() | ✅         |
+| `array`            | `*frankenphp.Array` | ❌       | frankenphp.GoArray()  | frankenphp.PHPArray()  | ✅         |
+| `mixed`            | `any`               | ❌       | `GoValue()`           | `PHPValue()`           | ❌         |
+| `object`           | `struct`            | ❌       | _尚未实现_            | _尚未实现_             | ❌         |
+
+> [!NOTE]
+> 此表尚不详尽，将随着 FrankenPHP 类型 API 变得更加完整而完善。
+>
+> 特别是对于类方法，目前支持原始类型和数组。对象尚不能用作方法参数或返回类型。
+
+如果你参考上一节的代码片段，你可以看到助手用于转换第一个参数和返回值。我们的 `repeat_this()` 函数的第二和第三个参数不需要转换，因为底层类型的内存表示对于 C 和 Go 都是相同的。
+
+#### 处理数组
+
+FrankenPHP 通过 `frankenphp.Array` 类型为 PHP 数组提供原生支持。此类型表示 PHP 索引数组（列表）和关联数组（哈希映射），具有有序的键值对。
+
+**在 Go 中创建和操作数组：**
+
+```go
+//export_php:function process_data(array $input): array
+func process_data(arr *C.zval) unsafe.Pointer {
+    // 将 PHP 数组转换为 Go
+    goArray := frankenphp.GoArray(unsafe.Pointer(arr))
+
+	result := &frankenphp.Array{}
+
+    result.SetInt(0, "first")
+    result.SetInt(1, "second")
+    result.Append("third") // 自动分配下一个整数键
+
+    result.SetString("name", "John")
+    result.SetString("age", int64(30))
+
+    for i := uint32(0); i < goArray.Len(); i++ {
+        key, value := goArray.At(i)
+        if key.Type == frankenphp.PHPStringKey {
+            result.SetString("processed_"+key.Str, value)
+        } else {
+            result.SetInt(key.Int+100, value)
+        }
+    }
+
+    // 转换回 PHP 数组
+    return frankenphp.PHPArray(result)
+}
+```
+
+**`frankenphp.Array` 的关键特性：**
+
+- **有序键值对** - 像 PHP 数组一样维护插入顺序
+- **混合键类型** - 在同一数组中支持整数和字符串键
+- **类型安全** - `PHPKey` 类型确保正确的键处理
+- **自动列表检测** - 转换为 PHP 时，自动检测数组应该是打包列表还是哈希映射
+- **不支持对象** - 目前，只有标量类型和数组可以用作值。提供对象将导致 PHP 数组中的 `null` 值。
+
+**可用方法：**
+
+- `SetInt(key int64, value any)` - 使用整数键设置值
+- `SetString(key string, value any)` - 使用字符串键设置值
+- `Append(value any)` - 使用下一个可用整数键添加值
+- `Len() uint32` - 获取元素数量
+- `At(index uint32) (PHPKey, any)` - 获取索引处的键值对
+- `frankenphp.PHPArray(arr *frankenphp.Array) unsafe.Pointer` - 转换为 PHP 数组
+
+### 声明原生 PHP 类
+
+生成器支持将 Go 结构体声明为**不透明类**，可用于创建 PHP 对象。你可以使用 `//export_php:class` 指令注释来定义 PHP 类。例如：
+
+```go
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+```
+
+#### 什么是不透明类？
+
+**不透明类**是内部结构（属性）对 PHP 代码隐藏的类。这意味着：
+
+- **无直接属性访问**：你不能直接从 PHP 读取或写入属性（`$user->name` 不起作用）
+- **仅方法接口** - 所有交互必须通过你定义的方法进行
+- **更好的封装** - 内部数据结构完全由 Go 代码控制
+- **类型安全** - 没有 PHP 代码使用错误类型破坏内部状态的风险
+- **更清晰的 API** - 强制设计适当的公共接口
+
+这种方法提供了更好的封装，并防止 PHP 代码意外破坏 Go 对象的内部状态。与对象的所有交互都必须通过你明确定义的方法进行。
+
+#### 为类添加方法
+
+由于属性不能直接访问，你**必须定义方法**来与不透明类交互。使用 `//export_php:method` 指令来定义行为：
+
+```go
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+
+//export_php:method User::getName(): string
+func (us *UserStruct) GetUserName() unsafe.Pointer {
+    return frankenphp.PHPString(us.Name, false)
+}
+
+//export_php:method User::setAge(int $age): void
+func (us *UserStruct) SetUserAge(age int64) {
+    us.Age = int(age)
+}
+
+//export_php:method User::getAge(): int
+func (us *UserStruct) GetUserAge() int64 {
+    return int64(us.Age)
+}
+
+//export_php:method User::setNamePrefix(string $prefix = "User"): void
+func (us *UserStruct) SetNamePrefix(prefix *C.zend_string) {
+    us.Name = frankenphp.GoString(unsafe.Pointer(prefix)) + ": " + us.Name
+}
+```
+
+#### 可空参数
+
+生成器支持在 PHP 签名中使用 `?` 前缀的可空参数。当参数可空时，它在你的 Go 函数中变成指针，允许你检查值在 PHP 中是否为 `null`：
+
+```go
+//export_php:method User::updateInfo(?string $name, ?int $age, ?bool $active): void
+func (us *UserStruct) UpdateInfo(name *C.zend_string, age *int64, active *bool) {
+    // 检查是否提供了 name（不为 null）
+    if name != nil {
+        us.Name = frankenphp.GoString(unsafe.Pointer(name))
+    }
+
+    // 检查是否提供了 age（不为 null）
+    if age != nil {
+        us.Age = int(*age)
+    }
+
+    // 检查是否提供了 active（不为 null）
+    if active != nil {
+        us.Active = *active
+    }
+}
+```
+
+**关于可空参数的要点：**
+
+- **可空原始类型**（`?int`、`?float`、`?bool`）在 Go 中变成指针（`*int64`、`*float64`、`*bool`）
+- **可空字符串**（`?string`）仍然是 `*C.zend_string`，但可以是 `nil`
+- **在解引用指针值之前检查 `nil`**
+- **PHP `null` 变成 Go `nil`** - 当 PHP 传递 `null` 时，你的 Go 函数接收 `nil` 指针
+
+> [!WARNING]
+> 目前，类方法有以下限制。**不支持对象**作为参数类型或返回类型。**完全支持数组**作为参数和返回类型。支持的类型：`string`、`int`、`float`、`bool`、`array` 和 `void`（用于返回类型）。**完全支持可空参数类型**，适用于所有标量类型（`?string`、`?int`、`?float`、`?bool`）。
+
+生成扩展后，你将被允许在 PHP 中使用类及其方法。请注意，你**不能直接访问属性**：
+
+```php
+<?php
+
+$user = new User();
+
+// ✅ 这可以工作 - 使用方法
+$user->setAge(25);
+echo $user->getName();           // 输出：（空，默认值）
+echo $user->getAge();            // 输出：25
+$user->setNamePrefix("Employee");
+
+// ✅ 这也可以工作 - 可空参数
+$user->updateInfo("John", 30, true);        // 提供所有参数
+$user->updateInfo("Jane", null, false);     // Age 为 null
+$user->updateInfo(null, 25, null);          // Name 和 active 为 null
+
+// ❌ 这不会工作 - 直接属性访问
+// echo $user->name;             // 错误：无法访问私有属性
+// $user->age = 30;              // 错误：无法访问私有属性
+```
+
+这种设计确保你的 Go 代码完全控制如何访问和修改对象的状态，提供更好的封装和类型安全。
+
+### 声明常量
+
+生成器支持使用两个指令将 Go 常量导出到 PHP：`//export_php:const` 用于全局常量，`//export_php:classconst` 用于类常量。这允许你在 Go 和 PHP 代码之间共享配置值、状态代码和其他常量。
+
+#### 全局常量
+
+使用 `//export_php:const` 指令创建全局 PHP 常量：
+
+```go
+//export_php:const
+const MAX_CONNECTIONS = 100
+
+//export_php:const
+const API_VERSION = "1.2.3"
+
+//export_php:const
+const STATUS_OK = iota
+
+//export_php:const
+const STATUS_ERROR = iota
+```
+
+#### 类常量
+
+使用 `//export_php:classconst ClassName` 指令创建属于特定 PHP 类的常量：
+
+```go
+//export_php:classconst User
+const STATUS_ACTIVE = 1
+
+//export_php:classconst User
+const STATUS_INACTIVE = 0
+
+//export_php:classconst User
+const ROLE_ADMIN = "admin"
+
+//export_php:classconst Order
+const STATE_PENDING = iota
+
+//export_php:classconst Order
+const STATE_PROCESSING = iota
+
+//export_php:classconst Order
+const STATE_COMPLETED = iota
+```
+
+类常量在 PHP 中使用类名作用域访问：
+
+```php
+<?php
+
+// 全局常量
+echo MAX_CONNECTIONS;    // 100
+echo API_VERSION;        // "1.2.3"
+
+// 类常量
+echo User::STATUS_ACTIVE;    // 1
+echo User::ROLE_ADMIN;       // "admin"
+echo Order::STATE_PENDING;   // 0
+```
+
+该指令支持各种值类型，包括字符串、整数、布尔值、浮点数和 iota 常量。使用 `iota` 时，生成器自动分配顺序值（0、1、2 等）。全局常量在你的 PHP 代码中作为全局常量可用，而类常量使用公共可见性限定在各自的类中。使用整数时，支持不同的可能记法（二进制、十六进制、八进制）并在 PHP 存根文件中按原样转储。
+
+你可以像在 Go 代码中习惯的那样使用常量。例如，让我们采用我们之前声明的 `repeat_this()` 函数，并将最后一个参数更改为整数：
+
+```go
+import (
+    "C"
+    "github.com/dunglas/frankenphp"
+    "strings"
+)
+
+//export_php:const
+const STR_REVERSE = iota
+
+//export_php:const
+const STR_NORMAL = iota
+
+//export_php:classconst StringProcessor
+const MODE_LOWERCASE = 1
+
+//export_php:classconst StringProcessor
+const MODE_UPPERCASE = 2
+
+//export_php:function repeat_this(string $str, int $count, int $mode): string
+func repeat_this(s *C.zend_string, count int64, mode int) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    result := strings.Repeat(str, int(count))
+    if mode == STR_REVERSE {
+        // 反转字符串
+    }
+
+    if mode == STR_NORMAL {
+        // 无操作，只是为了展示常量
+    }
+
+    return frankenphp.PHPString(result, false)
+}
+
+//export_php:class StringProcessor
+type StringProcessorStruct struct {
+    // 内部字段
+}
+
+//export_php:method StringProcessor::process(string $input, int $mode): string
+func (sp *StringProcessorStruct) Process(input *C.zend_string, mode int64) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(input))
+
+    switch mode {
+    case MODE_LOWERCASE:
+        str = strings.ToLower(str)
+    case MODE_UPPERCASE:
+        str = strings.ToUpper(str)
+    }
+
+    return frankenphp.PHPString(str, false)
+}
+```
+
+### 使用命名空间
+
+生成器支持使用 `//export_php:namespace` 指令将 PHP 扩展的函数、类和常量组织在命名空间下。这有助于避免命名冲突，并为扩展的 API 提供更好的组织。
+
+#### 声明命名空间
+
+在你的 Go 文件顶部使用 `//export_php:namespace` 指令，将所有导出的符号放在特定命名空间下：
+
+```go
+//export_php:namespace My\Extension
+package main
+
+import "C"
+
+//export_php:function hello(): string
+func hello() string {
+    return "Hello from My\\Extension namespace!"
+}
+
+//export_php:class User
+type UserStruct struct {
+    // 内部字段
+}
+
+//export_php:method User::getName(): string
+func (u *UserStruct) GetName() unsafe.Pointer {
+    return frankenphp.PHPString("John Doe", false)
+}
+
+//export_php:const
+const STATUS_ACTIVE = 1
+```
+
+#### 在 PHP 中使用命名空间扩展
+
+当声明命名空间时，所有函数、类和常量都放在 PHP 中的该命名空间下：
+
+```php
+<?php
+
+echo My\Extension\hello(); // "Hello from My\Extension namespace!"
+
+$user = new My\Extension\User();
+echo $user->getName(); // "John Doe"
+
+echo My\Extension\STATUS_ACTIVE; // 1
+```
+
+#### 重要说明
+
+- 每个文件只允许**一个**命名空间指令。如果找到多个命名空间指令，生成器将返回错误。
+- 命名空间适用于文件中的**所有**导出符号：函数、类、方法和常量。
+- 命名空间名称遵循 PHP 命名空间约定，使用反斜杠（`\`）作为分隔符。
+- 如果没有声明命名空间，符号将照常导出到全局命名空间。
+
+### 生成扩展
+
+这就是魔法发生的地方，现在可以生成你的扩展。你可以使用以下命令运行生成器：
+
+```console
+GEN_STUB_SCRIPT=php-src/build/gen_stub.php frankenphp extension-init my_extension.go
+```
+
+> [!NOTE]
+> 不要忘记将 `GEN_STUB_SCRIPT` 环境变量设置为你之前下载的 PHP 源代码中 `gen_stub.php` 文件的路径。这是在手动实现部分中提到的同一个 `gen_stub.php` 脚本。
+
+如果一切顺利，应该创建了一个名为 `build` 的新目录。此目录包含扩展的生成文件，包括带有生成的 PHP 函数存根的 `my_extension.go` 文件。
+
+### 将生成的扩展集成到 FrankenPHP 中
+
+我们的扩展现在已准备好编译并集成到 FrankenPHP 中。为此，请参阅 FrankenPHP [编译文档](compile.md)以了解如何编译 FrankenPHP。使用 `--with` 标志添加模块，指向你的模块路径：
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module/build
+```
+
+请注意，你指向在生成步骤中创建的 `/build` 子目录。但是，这不是强制性的：你也可以将生成的文件复制到你的模块目录并直接指向它。
+
+### 测试你的生成扩展
+
+你可以创建一个 PHP 文件来测试你创建的函数和类。例如，创建一个包含以下内容的 `index.php` 文件：
+
+```php
+<?php
+
+// 使用全局常量
+var_dump(repeat_this('Hello World', 5, STR_REVERSE));
+
+// 使用类常量
+$processor = new StringProcessor();
+echo $processor->process('Hello World', StringProcessor::MODE_LOWERCASE);  // "hello world"
+echo $processor->process('Hello World', StringProcessor::MODE_UPPERCASE);  // "HELLO WORLD"
+```
+
+一旦你按照上一节所示将扩展集成到 FrankenPHP 中，你就可以使用 `./frankenphp php-server` 运行此测试文件，你应该看到你的扩展正在工作。
+
+## 手动实现

+如果你想了解扩展的工作原理或需要完全控制你的扩展，你可以手动编写它们。这种方法给你完全的控制，但需要更多的样板代码。
+
+### 基本函数
+
+我们将看到如何在 Go 中编写一个简单的 PHP 扩展，定义一个新的原生函数。此函数将从 PHP 调用，并将触发一个在 Caddy 日志中记录消息的协程。此函数不接受任何参数并且不返回任何内容。
+
+#### 定义 Go 函数
+
+在你的模块中，你需要定义一个新的原生函数，该函数将从 PHP 调用。为此，创建一个你想要的名称的文件，例如 `extension.go`，并添加以下代码：
+
+```go
+package ext_go
+
+//#include "extension.h"
+import "C"
+import (
+    "unsafe"
+    "github.com/caddyserver/caddy/v2"
+    "github.com/dunglas/frankenphp"
+)
+
+func init() {
+    frankenphp.RegisterExtension(unsafe.Pointer(&C.ext_module_entry))
+}
+
+//export go_print_something
+func go_print_something() {
+    go func() {
+        caddy.Log().Info("Hello from a goroutine!")
+    }()
+}
+```
+
+`frankenphp.RegisterExtension()` 函数通过处理内部 PHP 注册逻辑简化了扩展注册过程。`go_print_something` 函数使用 `//export` 指令表示它将在我们将编写的 C 代码中可访问，这要归功于 CGO。
+
+在此示例中，我们的新函数将触发一个在 Caddy 日志中记录消息的协程。
+
+#### 定义 PHP 函数
+
+为了允许 PHP 调用我们的函数，我们需要定义相应的 PHP 函数。为此，我们将创建一个存根文件，例如 `extension.stub.php`，其中包含以下代码：
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+function go_print(): void {}
+```
+
+此文件定义了 `go_print()` 函数的签名，该函数将从 PHP 调用。`@generate-class-entries` 指令允许 PHP 自动为我们的扩展生成函数条目。
+
+这不是手动完成的，而是使用 PHP 源代码中提供的脚本（确保根据你的 PHP 源代码所在位置调整 `gen_stub.php` 脚本的路径）：
+
+```bash
+php ../php-src/build/gen_stub.php extension.stub.php
+```
+
+此脚本将生成一个名为 `extension_arginfo.h` 的文件，其中包含 PHP 知道如何定义和调用我们函数所需的信息。
+
+#### 编写 Go 和 C 之间的桥梁
+
+现在，我们需要编写 Go 和 C 之间的桥梁。在你的模块目录中创建一个名为 `extension.h` 的文件，内容如下：
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+接下来，创建一个名为 `extension.c` 的文件，该文件将执行以下步骤：
+
+- 包含 PHP 头文件；
+- 声明我们的新原生 PHP 函数 `go_print()`；
+- 声明扩展元数据。
+
+让我们首先包含所需的头文件：
+
+```c
+#include <php.h>
+#include "extension.h"
+#include "extension_arginfo.h"
+
+// 包含 Go 导出的符号
+#include "_cgo_export.h"
+```
+
+然后我们将 PHP 函数定义为原生语言函数：
+
+```c
+PHP_FUNCTION(go_print)
+{
+    ZEND_PARSE_PARAMETERS_NONE();
+
+    go_print_something();
+}
+
+zend_module_entry ext_module_entry = {
+    STANDARD_MODULE_HEADER,
+    "ext_go",
+    ext_functions, /* Functions */
+    NULL,          /* MINIT */
+    NULL,          /* MSHUTDOWN */
+    NULL,          /* RINIT */
+    NULL,          /* RSHUTDOWN */
+    NULL,          /* MINFO */
+    "0.1.1",
+    STANDARD_MODULE_PROPERTIES
+};
+```
+
+在这种情况下，我们的函数不接受参数并且不返回任何内容。它只是调用我们之前定义的 Go 函数，使用 `//export` 指令导出。
+
+最后，我们在 `zend_module_entry` 结构中定义扩展的元数据，例如其名称、版本和属性。这些信息对于 PHP 识别和加载我们的扩展是必需的。请注意，`ext_functions` 是指向我们定义的 PHP 函数的指针数组，它由 `gen_stub.php` 脚本在 `extension_arginfo.h` 文件中自动生成。
+
+扩展注册由我们在 Go 代码中调用的 FrankenPHP 的 `RegisterExtension()` 函数自动处理。
+
+### 高级用法
+
+现在我们知道了如何在 Go 中创建基本的 PHP 扩展，让我们复杂化我们的示例。我们现在将创建一个 PHP 函数，该函数接受一个字符串作为参数并返回其大写版本。
+
+#### 定义 PHP 函数存根
+
+为了定义新的 PHP 函数，我们将修改我们的 `extension.stub.php` 文件以包含新的函数签名：
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+/**
+ * 将字符串转换为大写。
+ *
+ * @param string $string 要转换的字符串。
+ * @return string 字符串的大写版本。
+ */
+function go_upper(string $string): string {}
+```
+
+> [!TIP]
+> 不要忽视函数的文档！你可能会与其他开发人员共享扩展存根，以记录如何使用你的扩展以及哪些功能可用。
+
+通过使用 `gen_stub.php` 脚本重新生成存根文件，`extension_arginfo.h` 文件应该如下所示：
+
+```c
+ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(arginfo_go_upper, 0, 1, IS_STRING, 0)
+    ZEND_ARG_TYPE_INFO(0, string, IS_STRING, 0)
+ZEND_END_ARG_INFO()
+
+ZEND_FUNCTION(go_upper);
+
+static const zend_function_entry ext_functions[] = {
+    ZEND_FE(go_upper, arginfo_go_upper)
+    ZEND_FE_END
+};
+```
+
+我们可以看到 `go_upper` 函数定义了一个 `string` 类型的参数和一个 `string` 的返回类型。
+
+#### Go 和 PHP/C 之间的类型转换
+
+你的 Go 函数不能直接接受 PHP 字符串作为参数。你需要将其转换为 Go 字符串。幸运的是，FrankenPHP 提供了助手函数来处理 PHP 字符串和 Go 字符串之间的转换，类似于我们在生成器方法中看到的。
+
+头文件保持简单：
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+我们现在可以在我们的 `extension.c` 文件中编写 Go 和 C 之间的桥梁。我们将 PHP 字符串直接传递给我们的 Go 函数：
+
+```c
+PHP_FUNCTION(go_upper)
+{
+    zend_string *str;
+
+    ZEND_PARSE_PARAMETERS_START(1, 1)
+        Z_PARAM_STR(str)
+    ZEND_PARSE_PARAMETERS_END();
+
+    zend_string *result = go_upper(str);
+    RETVAL_STR(result);
+}
+```
+
+你可以在 [PHP 内部手册](https://www.phpinternalsbook.com/php7/extensions_design/php_functions.html#parsing-parameters-zend-parse-parameters) 的专门页面中了解更多关于 `ZEND_PARSE_PARAMETERS_START` 和参数解析的信息。在这里，我们告诉 PHP 我们的函数接受一个 `string` 类型的强制参数作为 `zend_string`。然后我们将此字符串直接传递给我们的 Go 函数，并使用 `RETVAL_STR` 返回结果。
+
+只剩下一件事要做：在 Go 中实现 `go_upper` 函数。
+
+#### 实现 Go 函数
+
+我们的 Go 函数将接受 `*C.zend_string` 作为参数，使用 FrankenPHP 的助手函数将其转换为 Go 字符串，处理它，并将结果作为新的 `*C.zend_string` 返回。助手函数为我们处理所有内存管理和转换复杂性。
+
+```go
+import "strings"
+
+//export go_upper
+func go_upper(s *C.zend_string) *C.zend_string {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    upper := strings.ToUpper(str)
+
+    return (*C.zend_string)(frankenphp.PHPString(upper, false))
+}
+```
+
+这种方法比手动内存管理更清洁、更安全。FrankenPHP 的助手函数自动处理 PHP 的 `zend_string` 格式和 Go 字符串之间的转换。`PHPString()` 中的 `false` 参数表示我们想要创建一个新的非持久字符串（在请求结束时释放）。
+
+> [!TIP]
+> 在此示例中，我们不执行任何错误处理，但你应该始终检查指针不是 `nil` 并且数据在 Go 函数中使用之前是有效的。
+
+### 将扩展集成到 FrankenPHP 中
+
+我们的扩展现在已准备好编译并集成到 FrankenPHP 中。为此，请参阅 FrankenPHP [编译文档](compile.md)以了解如何编译 FrankenPHP。使用 `--with` 标志添加模块，指向你的模块路径：
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module
+```
+
+就是这样！你的扩展现在集成到 FrankenPHP 中，可以在你的 PHP 代码中使用。
+
+### 测试你的扩展
+
+将扩展集成到 FrankenPHP 后，你可以为你实现的函数创建一个包含示例的 `index.php` 文件：
+
+```php
+<?php
+
+// 测试基本函数
+go_print();
+
+// 测试高级函数
+echo go_upper("hello world") . "\n";
+```
+
+你现在可以使用 `./frankenphp php-server` 运行带有此文件的 FrankenPHP，你应该看到你的扩展正在工作。

+
+## 独立的二进制和基于 Alpine 的 Docker 镜像
+
+独立的二进制文件和基于 Alpine 的 Docker 镜像 (`dunglas/frankenphp:*-alpine`) 使用的是 [musl libc](https://musl.libc.org/) 而不是 [glibc and friends](https://www.etalabs.net/compare_libcs.html)，为的是保持较小的二进制大小。这可能会导致一些兼容性问题。特别是，glob 标志 `GLOB_BRACE` [不可用](https://www.php.net/manual/en/function.glob.php)。
+
+## 在 Docker 中使用 `https://127.0.0.1`
+
+默认情况下，FrankenPHP 会为 `localhost` 生成一个 TLS 证书。
+这是本地开发最简单且推荐的选项。
+
+如果确实想使用 `127.0.0.1` 作为主机，可以通过将服务器名称设置为 `127.0.0.1` 来配置它以为其生成证书。
+
+如果你使用 Docker，因为 [Docker 网络](https://docs.docker.com/network/) 问题，只做这些是不够的。
+你将收到类似于以下内容的 TLS 错误 `curl: (35) LibreSSL/3.3.6: error:1404B438:SSL routines:ST_CONNECT:tlsv1 alert internal error`。
+
+如果你使用的是 Linux，解决方案是使用 [使用宿主机网络](https://docs.docker.com/network/network-tutorial-host/)：
+
+```console
+docker run \
+    -e SERVER_NAME="127.0.0.1" \
+    -v $PWD:/app/public \
+    --network host \
+    dunglas/frankenphp
+```
+
+Mac 和 Windows 不支持 Docker 使用宿主机网络。在这些平台上，你必须猜测容器的 IP 地址并将其包含在服务器名称中。
+
+运行 `docker network inspect bridge` 并查看 `Containers`，找到 `IPv4Address` 当前分配的最后一个 IP 地址，并增加 1。如果没有容器正在运行，则第一个分配的 IP 地址通常为 `172.17.0.2`。
+
+然后将其包含在 `SERVER_NAME` 环境变量中：
+
+```console
+docker run \
+    -e SERVER_NAME="127.0.0.1, 172.17.0.3" \
+    -v $PWD:/app/public \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+> [!CAUTION]
+>
+> 请务必将 `172.17.0.3` 替换为将分配给容器的 IP。
+
+你现在应该能够从主机访问 `https://127.0.0.1`。
+
+如果不是这种情况，请在调试模式下启动 FrankenPHP 以尝试找出问题：
+
+```console
+docker run \
+    -e CADDY_GLOBAL_OPTIONS="debug" \
+    -e SERVER_NAME="127.0.0.1" \
+    -v $PWD:/app/public \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+## Composer 脚本引用 `@php`
+
+[Composer 脚本](https://getcomposer.org/doc/articles/scripts.md) 可能想要执行一个 PHP 二进制文件来完成一些任务，例如在 [Laravel 项目](laravel.md) 中运行 `@php artisan package:discover --ansi`。这 [目前失败](https://github.com/php/frankenphp/issues/483#issuecomment-1899890915) 的原因有两个：
+
+- Composer 不知道如何调用 FrankenPHP 二进制文件；
+- Composer 可以在命令中使用 `-d` 标志添加 PHP 设置，而 FrankenPHP 目前尚不支持。
+
+作为一种变通方法，我们可以在 `/usr/local/bin/php` 中创建一个 Shell 脚本，该脚本会去掉不支持的参数，然后调用 FrankenPHP:
+
+```bash
+#!/usr/bin/env bash
+args=("$@")
+index=0
+for i in "$@"
+do
+    if [ "$i" == "-d" ]; then
+        unset 'args[$index]'
+        unset 'args[$index+1]'
+    fi
+    index=$((index+1))
+done
+
+/usr/local/bin/frankenphp php-cli ${args[@]}
+```
+
+然后将环境变量 `PHP_BINARY` 设置为我们 `php` 脚本的路径，并运行 Composer：
+
+```console
+export PHP_BINARY=/usr/local/bin/php
+composer install
+```
+
+## 使用静态二进制文件排查 TLS/SSL 问题
+
+在使用静态二进制文件时，您可能会遇到以下与TLS相关的错误，例如在使用STARTTLS发送电子邮件时：
+
+```text
+Unable to connect with STARTTLS: stream_socket_enable_crypto(): SSL operation failed with code 5. OpenSSL Error messages:
+error:80000002:system library::No such file or directory
+error:80000002:system library::No such file or directory
+error:80000002:system library::No such file or directory
+error:0A000086:SSL routines::certificate verify failed
+```
+
+由于静态二进制不捆绑 TLS 证书，因此您需要将 OpenSSL 指向本地 CA 证书安装。
+
+检查 [`openssl_get_cert_locations()`](https://www.php.net/manual/en/function.openssl-get-cert-locations.php) 的输出，
+以找到 CA 证书必须安装的位置，并将它们存储在该位置。
+
+> [!WARNING]
+>
+> Web 和命令行界面可能有不同的设置。
+> 确保在适当的上下文中运行 `openssl_get_cert_locations()`。
+
+[从Mozilla提取的CA证书可以在curl网站上下载](https://curl.se/docs/caextract.html)。
+
+或者，许多发行版，包括 Debian、Ubuntu 和 Alpine，提供名为 `ca-certificates` 的软件包，其中包含这些证书。
+
+还可以使用 `SSL_CERT_FILE` 和 `SSL_CERT_DIR` 来提示 OpenSSL 在哪里查找 CA 证书：
+
+```console
+# Set TLS certificates environment variables
+export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
+export SSL_CERT_DIR=/etc/ssl/certs
+```

+```
+
+尽情享受吧！
+
+## 本地安装
+
+或者，你可以从本地机器上使用 FrankenPHP 运行 Laravel 项目：
+
+1. [下载与你的系统相对应的二进制文件](https://github.com/php/frankenphp/releases)
+2. 将以下配置添加到 Laravel 项目根目录中名为 `Caddyfile` 的文件中：
+
+   ```caddyfile
+   {
+   	frankenphp
+   }
+
+   # 服务器的域名
+   localhost {
+   	# 将 webroot 设置为 public/ 目录
+   	root public/

+   	# 执行当前目录中的 PHP 文件并提供资源
+   	php_server {
+   	    try_files {path} index.php
+       }
+   }
+   ```
+
+3. 从 Laravel 项目的根目录启动 FrankenPHP：`frankenphp run`
+
+## Laravel Octane
+
+Octane 可以通过 Composer 包管理器安装：
+
+```console
+composer require laravel/octane
+```
+
+安装 Octane 后，你可以执行 `octane:install` Artisan 命令，该命令会将 Octane 的配置文件安装到你的应用程序中：
+
+```console
+php artisan octane:install --server=frankenphp
+```
+
+Octane 服务可以通过 `octane:frankenphp` Artisan 命令启动。
+
+```console
+php artisan octane:frankenphp
+```
+
+`octane:frankenphp` 命令可以采用以下选项：
+
+- `--host`: 服务器应绑定到的 IP 地址（默认值: `127.0.0.1`）
+- `--port`: 服务器应可用的端口（默认值: `8000`）
+- `--admin-port`: 管理服务器应可用的端口（默认值: `2019`）
+- `--workers`: 应可用于处理请求的 worker 数（默认值: `auto`）
+- `--max-requests`: 在 worker 重启之前要处理的请求数（默认值: `500`）
+- `--caddyfile`：FrankenPHP `Caddyfile` 文件的路径（默认： [Laravel Octane 中的存根 `Caddyfile`](https://github.com/laravel/octane/blob/2.x/src/Commands/stubs/Caddyfile)）
+- `--https`: 开启 HTTPS、HTTP/2 和 HTTP/3，自动生成和延长证书
+- `--http-redirect`: 启用 HTTP 到 HTTPS 重定向（仅在使用 `--https` 时启用）
+- `--watch`: 修改应用程序时自动重新加载服务器
+- `--poll`: 在监视时使用文件系统轮询，以便通过网络监视文件
+- `--log-level`: 在指定日志级别或高于指定日志级别的日志消息
+
+> [!TIP]
+> 要获取结构化的 JSON 日志（在使用日志分析解决方案时非常有用），请明确传递 `--log-level` 选项。
+
+你可以了解更多关于 [Laravel Octane 官方文档](https://laravel.com/docs/octane)。
+
+## Laravel 应用程序作为独立的可执行文件
+
+使用[FrankenPHP 的应用嵌入功能](embed.md)，可以将 Laravel 应用程序作为
+独立的二进制文件分发。
+
+按照以下步骤将您的Laravel应用程序打包为Linux的独立二进制文件：
+
+1. 在您的应用程序的存储库中创建一个名为 `static-build.Dockerfile` 的文件:
+
+   ```dockerfile
+   FROM --platform=linux/amd64 dunglas/frankenphp:static-builder-gnu
+   # 如果你打算在 musl-libc 系统上运行该二进制文件，请使用 static-builder-musl
+
+   # 复制你的应用
+   WORKDIR /go/src/app/dist/app
+   COPY . .
+
+   # 删除测试和其他不必要的文件以节省空间
+   # 或者，将这些文件添加到 .dockerignore 文件中
+   RUN rm -Rf tests/
+
+   # 复制 .env 文件
+   RUN cp .env.example .env
+   # 将 APP_ENV 和 APP_DEBUG 更改为适合生产环境
+   RUN sed -i'' -e 's/^APP_ENV=.*/APP_ENV=production/' -e 's/^APP_DEBUG=.*/APP_DEBUG=false/' .env
+
+   # 根据需要对您的 .env 文件进行其他更改
+
+   # 安装依赖项
+   RUN composer install --ignore-platform-reqs --no-dev -a
+
+   # 构建静态二进制文件
+   WORKDIR /go/src/app/
+   RUN EMBED=dist/app/ ./build-static.sh
+   ```
+
+   > [!CAUTION]
+   >
+   > 一些 `.dockerignore` 文件
+   > 将忽略 `vendor/` 目录和 `.env` 文件。在构建之前，请确保调整或删除 `.dockerignore` 文件。
+
+2. 构建:
+
+   ```console
+   docker build -t static-laravel-app -f static-build.Dockerfile .
+   ```
+
+3. 提取二进制:
+
+   ```console
+   docker cp $(docker create --name static-laravel-app-tmp static-laravel-app):/go/src/app/dist/frankenphp-linux-x86_64 frankenphp ; docker rm static-laravel-app-tmp
+   ```
+
+4. 填充缓存：
+
+   ```console
+   frankenphp php-cli artisan optimize
+   ```
+
+5. 运行数据库迁移（如果有的话）：
+
+   ```console
+   frankenphp php-cli artisan migrate
+   ```
+
+6. 生成应用程序的密钥：
+
+   ```console

+
+### 更改存储路径
+
+默认情况下，Laravel 将上传的文件、缓存、日志等存储在应用程序的 `storage/` 目录中。
+这不适合嵌入式应用，因为每个新版本将被提取到不同的临时目录中。
+
+设置 `LARAVEL_STORAGE_PATH` 环境变量（例如，在 `.env` 文件中）或调用 `Illuminate\Foundation\Application::useStoragePath()` 方法以使用临时目录之外的目录。
+
+### 使用独立二进制文件运行 Octane
+
+甚至可以将 Laravel Octane 应用打包为独立的二进制文件！
+
+为此，[正确安装 Octane](#laravel-octane) 并遵循 [前一部分](#laravel-应用程序作为独立的可执行文件) 中描述的步骤。
+
+然后，通过 Octane 在工作模式下启动 FrankenPHP，运行：
+
+```console
+PATH="$PWD:$PATH" frankenphp php-cli artisan octane:frankenphp
+```
+
+> [!CAUTION]
+>
+> 为了使命令有效，独立二进制文件**必须**命名为 `frankenphp`
+> 因为 Octane 需要一个名为 `frankenphp` 的程序在路径中可用。

+# 性能
+
+默认情况下，FrankenPHP 尝试在性能和易用性之间提供良好的折衷。
+但是，通过使用适当的配置，可以大幅提高性能。
+
+## 线程和 Worker 数量
+
+默认情况下，FrankenPHP 启动的线程和 worker（在 worker 模式下）数量是可用 CPU 数量的 2 倍。
+
+适当的值很大程度上取决于你的应用程序是如何编写的、它做什么以及你的硬件。
+我们强烈建议更改这些值。为了获得最佳的系统稳定性，建议 `num_threads` x `memory_limit` < `available_memory`。
+
+要找到正确的值，最好运行模拟真实流量的负载测试。
+[k6](https://k6.io) 和 [Gatling](https://gatling.io) 是很好的工具。
+
+要配置线程数，请使用 `php_server` 和 `php` 指令的 `num_threads` 选项。
+要更改 worker 数量，请使用 `frankenphp` 指令的 `worker` 部分的 `num` 选项。
+
+### `max_threads`
+
+虽然准确了解你的流量情况总是更好，但现实应用往往更加
+不可预测。`max_threads` [配置](config.md#caddyfile-config) 允许 FrankenPHP 在运行时自动生成额外线程，直到指定的限制。
+`max_threads` 可以帮助你确定需要多少线程来处理你的流量，并可以使服务器对延迟峰值更具弹性。
+如果设置为 `auto`，限制将基于你的 `php.ini` 中的 `memory_limit` 进行估算。如果无法这样做，
+`auto` 将默认为 2x `num_threads`。请记住，`auto` 可能会严重低估所需的线程数。
+`max_threads` 类似于 PHP FPM 的 [pm.max_children](https://www.php.net/manual/en/install.fpm.configuration.php#pm.max-children)。主要区别是 FrankenPHP 使用线程而不是
+进程，并根据需要自动在不同的 worker 脚本和"经典模式"之间委派它们。
+
+## Worker 模式
+
+启用 [worker 模式](worker.md) 大大提高了性能，
+但你的应用必须适配以兼容此模式：
+你需要创建一个 worker 脚本并确保应用不会泄漏内存。
+
+## 不要使用 musl
+
+官方 Docker 镜像的 Alpine Linux 变体和我们提供的默认二进制文件使用 [musl libc](https://musl.libc.org)。
+
+众所周知，当使用这个替代 C 库而不是传统的 GNU 库时，PHP [更慢](https://gitlab.alpinelinux.org/alpine/aports/-/issues/14381)，
+特别是在以 ZTS 模式（线程安全）编译时，这是 FrankenPHP 所必需的。在大量线程环境中，差异可能很显著。
+
+另外，[一些错误只在使用 musl 时发生](https://github.com/php/php-src/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen+label%3ABug+musl)。
+
+在生产环境中，我们建议使用链接到 glibc 的 FrankenPHP。
+
+这可以通过使用 Debian Docker 镜像（默认）、从我们的 [Releases](https://github.com/php/frankenphp/releases) 下载 -gnu 后缀二进制文件，或通过[从源代码编译 FrankenPHP](compile.md) 来实现。
+
+或者，我们提供使用 [mimalloc 分配器](https://github.com/microsoft/mimalloc) 编译的静态 musl 二进制文件，这缓解了线程场景中的问题。
+
+## Go 运行时配置
+
+FrankenPHP 是用 Go 编写的。
+
+一般来说，Go 运行时不需要任何特殊配置，但在某些情况下，
+特定的配置可以提高性能。
+
+你可能想要将 `GODEBUG` 环境变量设置为 `cgocheck=0`（FrankenPHP Docker 镜像中的默认值）。
+
+如果你在容器（Docker、Kubernetes、LXC...）中运行 FrankenPHP 并限制容器的可用内存，
+请将 `GOMEMLIMIT` 环境变量设置为可用内存量。
+
+有关更多详细信息，[专门针对此主题的 Go 文档页面](https://pkg.go.dev/runtime#hdr-Environment_Variables) 是充分利用运行时的必读内容。
+
+## `file_server`
+
+默认情况下，`php_server` 指令自动设置文件服务器来
+提供存储在根目录中的静态文件（资产）。
+
+此功能很方便，但有成本。
+要禁用它，请使用以下配置：
+
+```caddyfile
+php_server {
+    file_server off
+}
+```
+
+## `try_files`
+
+除了静态文件和 PHP 文件外，`php_server` 还会尝试提供你应用程序的索引
+和目录索引文件（`/path/` -> `/path/index.php`）。如果你不需要目录索引，
+你可以通过明确定义 `try_files` 来禁用它们，如下所示：
+
+```caddyfile
+php_server {
+    try_files {path} index.php
+    root /root/to/your/app # 在这里明确添加根目录允许更好的缓存
+}
+```
+
+这可以显著减少不必要的文件操作数量。
+
+另一种具有 0 个不必要文件系统操作的方法是改用 `php` 指令并按路径将
+文件与 PHP 分开。如果你的整个应用程序由一个入口文件提供服务，这种方法效果很好。
+一个在 `/assets` 文件夹后面提供静态文件的示例[配置](config.md#caddyfile-config)可能如下所示：
+
+```caddyfile
+route {
+    @assets {
+        path /assets/*
+    }
+
+    # /assets 后面的所有内容都由文件服务器处理
+    file_server @assets {
+        root /root/to/your/app
+    }
+
+    # 不在 /assets 中的所有内容都由你的索引或 worker PHP 文件处理
+    rewrite index.php
+    php {
+        root /root/to/your/app # 在这里明确添加根目录允许更好的缓存
+    }
+}
+```
+
+## 占位符
+
+你可以在 `root` 和 `env` 指令中使用[占位符](https://caddyserver.com/docs/conventions#placeholders)。
+但是，这会阻止缓存这些值，并带来显著的性能成本。
+
+如果可能，请避免在这些指令中使用占位符。
+
+## `resolve_root_symlink`
+
+默认情况下，如果文档根目录是符号链接，FrankenPHP 会自动解析它（这对于 PHP 正常工作是必要的）。
+如果文档根目录不是符号链接，你可以禁用此功能。
+
+```caddyfile
+php_server {
+    resolve_root_symlink false
+}
+```
+
+如果 `root` 指令包含[占位符](https://caddyserver.com/docs/conventions#placeholders)，这将提高性能。
+在其他情况下，收益将可以忽略不计。
+
+## 日志
+
+日志显然非常有用，但根据定义，
+它需要 I/O 操作和内存分配，这会大大降低性能。
+确保你[正确设置日志级别](https://caddyserver.com/docs/caddyfile/options#log)，
+并且只记录必要的内容。
+
+## PHP 性能
+
+FrankenPHP 使用官方 PHP 解释器。
+所有常见的 PHP 相关性能优化都适用于 FrankenPHP。
+
+特别是：
+
+- 检查 [OPcache](https://www.php.net/manual/zh/book.opcache.php) 是否已安装、启用并正确配置
+- 启用 [Composer 自动加载器优化](https://getcomposer.org/doc/articles/autoloader-optimization.md)
+- 确保 `realpath` 缓存对于你的应用程序需求足够大
+- 使用[预加载](https://www.php.net/manual/zh/opcache.preloading.php)

+# 在生产环境中部署
+
+在本教程中，我们将学习如何使用 Docker Compose 在单个服务器上部署 PHP 应用程序。
+
+如果你使用的是 Symfony，请阅读 Symfony Docker 项目（使用 FrankenPHP）的 [在生产环境中部署](https://github.com/dunglas/symfony-docker/blob/main/docs/production.md) 文档条目。
+
+如果你使用的是 API Platform（同样使用 FrankenPHP），请参阅 [框架的部署文档](https://api-platform.com/docs/deployment/)。
+
+## 准备应用
+
+首先，在 PHP 项目的根目录中创建一个 `Dockerfile`：
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# 请将 "your-domain-name.example.com" 替换为你的域名
+ENV SERVER_NAME=your-domain-name.example.com
+# 如果要禁用 HTTPS，请改用以下值：
+#ENV SERVER_NAME=:80
+
+# 如果你的项目不使用 "public" 目录作为 web 根目录，你可以在这里设置：
+# ENV SERVER_ROOT=web/
+
+# 启用 PHP 生产配置
+RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"
+
+# 将项目的 PHP 文件复制到 public 目录中
+COPY . /app/public
+# 如果你使用 Symfony 或 Laravel，你需要复制整个项目：
+#COPY . /app
+```
+
+有关更多详细信息和选项，请参阅 [构建自定义 Docker 镜像](docker.md)。
+要了解如何自定义配置，请安装 PHP 扩展和 Caddy 模块。
+
+如果你的项目使用 Composer，
+请务必将其包含在 Docker 镜像中并安装你的依赖。
+
+然后，添加一个 `compose.yaml` 文件：
+
+```yaml
+services:
+  php:
+    image: dunglas/frankenphp
+    restart: always
+    ports:
+      - "80:80" # HTTP
+      - "443:443" # HTTPS
+      - "443:443/udp" # HTTP/3
+    volumes:
+      - caddy_data:/data
+      - caddy_config:/config
+
+# Caddy 证书和配置所需的挂载目录
+volumes:
+  caddy_data:
+  caddy_config:
+```
+
+> [!NOTE]
+>
+> 前面的示例适用于生产用途。
+> 在开发中，你可能希望使用挂载目录，不同的 PHP 配置和不同的 `SERVER_NAME` 环境变量值。
+>
+> 见 [Symfony Docker](https://github.com/dunglas/symfony-docker) 项目
+> （使用 FrankenPHP）作为使用多阶段镜像的更高级示例，
+> Composer、额外的 PHP 扩展等。
+
+最后，如果你使用 Git，请提交这些文件并推送。
+
+## 准备服务器
+
+若要在生产环境中部署应用程序，需要一台服务器。
+在本教程中，我们将使用 DigitalOcean 提供的虚拟机，但任何 Linux 服务器都可以工作。
+如果你已经有安装了 Docker 的 Linux 服务器，你可以直接跳到 [下一节](#配置域名)。
+
+否则，请使用 [此会员链接](https://m.do.co/c/5d8aabe3ab80) 获得 200 美元的免费信用额度，创建一个帐户，然后单击“Create a Droplet”。
+然后，单击“Choose an image”部分下的“Marketplace”选项卡，然后搜索名为“Docker”的应用程序。
+这将配置已安装最新版本的 Docker 和 Docker Compose 的 Ubuntu 服务器！
+
+出于测试目的，最便宜的就足够了。
+对于实际的生产用途，你可能需要在“general purpose”部分中选择一个计划来满足你的需求。
+
+![使用 Docker 在 DigitalOcean 上部署 FrankenPHP](../digitalocean-droplet.png)
+
+你可以保留其他设置的默认值，也可以根据需要进行调整。
+不要忘记添加你的 SSH 密钥或创建密码，然后点击“完成并创建”按钮。
+
+然后，在 Droplet 预配时等待几秒钟。
+Droplet 准备就绪后，使用 SSH 进行连接：
+
+```console
+ssh root@<droplet-ip>
+```
+
+## 配置域名
+
+在大多数情况下，你需要将域名与你的网站相关联。
+如果你还没有域名，则必须通过注册商购买。
+
+然后为你的域名创建类型为 `A` 的 DNS 记录，指向服务器的 IP 地址：
+
+```dns
+your-domain-name.example.com.  IN  A     207.154.233.113
+```
+
+DigitalOcean 域服务示例（“Networking” > “Domains”）：
+
+![在 DigitalOcean 上配置 DNS](../digitalocean-dns.png)
+
+> [!NOTE]
+>
+> Let's Encrypt 是 FrankenPHP 默认用于自动生成 TLS 证书的服务，不支持使用裸 IP 地址。使用域名是使用 Let's Encrypt 的必要条件。
+
+## 部署
+
+使用 `git clone`、`scp` 或任何其他可能适合你需要的工具在服务器上复制你的项目。
+如果使用 GitHub，则可能需要使用 [部署密钥](https://docs.github.com/en/free-pro-team@latest/developers/overview/managing-deploy-keys#deploy-keys)。
+部署密钥也 [由 GitLab 支持](https://docs.gitlab.com/ee/user/project/deploy_keys/)。
+
+Git 示例：
+
+```console
+git clone git@github.com:<username>/<project-name>.git
+```
+
+进入包含项目 (`<project-name>`) 的目录，并在生产模式下启动应用：
+
+```console
+docker compose up --wait
+```
+
+你的服务器已启动并运行，并且已自动为你生成 HTTPS 证书。
+去 `https://your-domain-name.example.com` 享受吧！
+
+> [!CAUTION]
+>
+> Docker 有一个缓存层，请确保每个部署都有正确的构建，或者使用 `--no-cache` 选项重新构建项目以避免缓存问题。
+
+## 在多个节点上部署
+
+如果要在计算机集群上部署应用程序，可以使用 [Docker Swarm](https://docs.docker.com/engine/swarm/stack-deploy/)，
+它与提供的 Compose 文件兼容。
+要在 Kubernetes 上部署，请查看 [API 平台提供的 Helm 图表](https://api-platform.com/docs/deployment/kubernetes/)，同样也使用 FrankenPHP。

+# 创建静态构建
+
+与其使用本地安装的PHP库，
+由于伟大的 [static-php-cli 项目](https://github.com/crazywhalecc/static-php-cli)，创建一个静态或基本静态的 FrankenPHP 构建是可能的（尽管它的名字，这个项目支持所有的 SAPI，而不仅仅是 CLI）。
+
+使用这种方法，我们可构建一个包含 PHP 解释器、Caddy Web 服务器和 FrankenPHP 的可移植二进制文件！
+
+完全静态的本地可执行文件不需要任何依赖，并且可以在 [`scratch` Docker 镜像](https://docs.docker.com/build/building/base-images/#create-a-minimal-base-image-using-scratch) 上运行。
+然而，它们无法加载动态 PHP 扩展（例如 Xdebug），并且由于使用了 musl libc，有一些限制。
+
+大多数静态二进制文件只需要 `glibc` 并且可以加载动态扩展。
+
+在可能的情况下，我们建议使用基于glibc的、主要是静态构建的版本。
+
+FrankenPHP 还支持 [将 PHP 应用程序嵌入到静态二进制文件中](embed.md)。
+
+## Linux
+
+我们提供了一个 Docker 镜像来构建 Linux 静态二进制文件：
+
+### 基于musl的完全静态构建
+
+对于一个在任何Linux发行版上运行且不需要依赖项的完全静态二进制文件，但不支持动态加载扩展：
+
+```console
+docker buildx bake --load static-builder-musl
+docker cp $(docker create --name static-builder-musl dunglas/frankenphp:static-builder-musl):/go/src/app/dist/frankenphp-linux-$(uname -m) frankenphp ; docker rm static-builder-musl
+```
+
+为了在高度并发的场景中获得更好的性能，请考虑使用 [mimalloc](https://github.com/microsoft/mimalloc) 分配器。
+
+```console
+docker buildx bake --load --set static-builder-musl.args.MIMALLOC=1 static-builder-musl
+```
+
+### 基于glibc的，主要静态构建（支持动态扩展）
+
+对于一个支持动态加载 PHP 扩展的二进制文件，同时又将所选扩展静态编译：
+
+```console
+docker buildx bake --load static-builder-gnu
+docker cp $(docker create --name static-builder-gnu dunglas/frankenphp:static-builder-gnu):/go/src/app/dist/frankenphp-linux-$(uname -m) frankenphp ; docker rm static-builder-gnu
+```
+
+该二进制文件支持所有glibc版本2.17及以上，但不支持基于musl的系统（如Alpine Linux）。
+
+生成的主要是静态的（除了 `glibc`）二进制文件名为 `frankenphp`，并且可以在当前目录中找到。
+
+如果你想在没有 Docker 的情况下构建静态二进制文件，请查看 macOS 说明，它也适用于 Linux。
+
+### 自定义扩展
+
+默认情况下，大多数流行的 PHP 扩展都会被编译。
+
+为了减少二进制文件的大小和减少攻击面，您可以选择使用 `PHP_EXTENSIONS` Docker ARG 构建的扩展列表。
+
+例如，运行以下命令仅构建 `opcache` 扩展：
+
+```console
+docker buildx bake --load --set static-builder-musl.args.PHP_EXTENSIONS=opcache,pdo_sqlite static-builder-musl
+# ...
+```
+
+若要将启用其他功能的库添加到已启用的扩展中，可以使用 `PHP_EXTENSION_LIBS` Docker 参数：
+
+```console
+docker buildx bake \
+  --load \
+  --set static-builder-musl.args.PHP_EXTENSIONS=gd \
+  --set static-builder-musl.args.PHP_EXTENSION_LIBS=libjpeg,libwebp \
+  static-builder-musl
+```
+
+### 额外的 Caddy 模块
+
+要向 [xcaddy](https://github.com/caddyserver/xcaddy) 添加额外的 Caddy 模块或传递其他参数，请使用 `XCADDY_ARGS` Docker 参数：
+
+```console
+docker buildx bake \
+  --load \
+  --set static-builder-musl.args.XCADDY_ARGS="--with github.com/darkweak/souin/plugins/caddy --with github.com/dunglas/caddy-cbrotli --with github.com/dunglas/mercure/caddy --with github.com/dunglas/vulcain/caddy" \
+  static-builder-musl
+```
+
+在本例中，我们为 Caddy 添加了 [Souin](https://souin.io) HTTP 缓存模块，以及 [cbrotli](https://github.com/dunglas/caddy-cbrotli)、[Mercure](https://mercure.rocks) 和 [Vulcain](https://vulcain.rocks) 模块。
+
+> [!TIP]
+>
+> 如果 `XCADDY_ARGS` 为空或未设置，则默认包含 cbrotli、Mercure 和 Vulcain 模块。
+> 如果自定义了 `XCADDY_ARGS` 的值，则必须显式地包含它们。
+
+参见：[自定义构建](#自定义构建)
+
+### GitHub Token
+
+如果遇到了 GitHub API 速率限制，请在 `GITHUB_TOKEN` 的环境变量中设置 GitHub Personal Access Token：
+
+```console
+GITHUB_TOKEN="xxx" docker --load buildx bake static-builder-musl
+# ...
+```
+
+## macOS
+
+运行以下脚本以创建适用于 macOS 的静态二进制文件（需要先安装 [Homebrew](https://brew.sh/)）：
+
+```console
+git clone https://github.com/php/frankenphp
+cd frankenphp
+./build-static.sh
+```
+
+注意：此脚本也适用于 Linux（可能也适用于其他 Unix 系统），我们提供的用于构建静态二进制的 Docker 镜像也在内部使用这个脚本。
+
+## 自定义构建
+
+以下环境变量可以传递给 `docker build` 和 `build-static.sh`
+脚本来自定义静态构建：
+
+- `FRANKENPHP_VERSION`: 要使用的 FrankenPHP 版本
+- `PHP_VERSION`: 要使用的 PHP 版本
+- `PHP_EXTENSIONS`: 要构建的 PHP 扩展（[支持的扩展列表](https://static-php.dev/zh/guide/extensions.html)）
+- `PHP_EXTENSION_LIBS`: 要构建的额外库，为扩展添加额外的功能
+- `XCADDY_ARGS`：传递给 [xcaddy](https://github.com/caddyserver/xcaddy) 的参数，例如用于添加额外的 Caddy 模块
+- `EMBED`: 要嵌入二进制文件的 PHP 应用程序的路径
+- `CLEAN`: 设置后，libphp 及其所有依赖项都是重新构建的（不使用缓存）
+- `NO_COMPRESS`: 不要使用UPX压缩生成的二进制文件
+- `DEBUG_SYMBOLS`: 设置后，调试符号将被保留在二进制文件内
+- `MIMALLOC`: (实验性，仅限Linux) 用[mimalloc](https://github.com/microsoft/mimalloc)替换musl的mallocng，以提高性能。我们仅建议在musl目标构建中使用此选项，对于glibc，建议禁用此选项，并在运行二进制文件时使用[`LD_PRELOAD`](https://microsoft.github.io/mimalloc/overrides.html)。
+- `RELEASE`: （仅限维护者）设置后，生成的二进制文件将上传到 GitHub 上
+
+## 扩展
+
+使用glibc或基于macOS的二进制文件，您可以动态加载PHP扩展。然而，这些扩展必须使用ZTS支持进行编译。
+由于大多数软件包管理器目前不提供其扩展的 ZTS 版本，因此您必须自己编译它们。
+
+为此，您可以构建并运行 `static-builder-gnu` Docker 容器，远程进入它，并使用 `./configure --with-php-config=/go/src/app/dist/static-php-cli/buildroot/bin/php-config` 编译扩展。
+
+关于 [Xdebug 扩展](https://xdebug.org) 的示例步骤：
+
+```console
+docker build -t gnu-ext -f static-builder-gnu.Dockerfile --build-arg FRANKENPHP_VERSION=1.0 .
+docker create --name static-builder-gnu -it gnu-ext /bin/sh
+docker start static-builder-gnu
+docker exec -it static-builder-gnu /bin/sh
+cd /go/src/app/dist/static-php-cli/buildroot/bin
+git clone https://github.com/xdebug/xdebug.git && cd xdebug
+source scl_source enable devtoolset-10
+../phpize
+./configure --with-php-config=/go/src/app/dist/static-php-cli/buildroot/bin/php-config
+make
+exit
+docker cp static-builder-gnu:/go/src/app/dist/static-php-cli/buildroot/bin/xdebug/modules/xdebug.so xdebug-zts.so
+docker cp static-builder-gnu:/go/src/app/dist/frankenphp-linux-$(uname -m) ./frankenphp
+docker stop static-builder-gnu
+docker rm static-builder-gnu
+docker rmi gnu-ext
+```
+
+这将在当前目录中创建 `frankenphp` 和 `xdebug-zts.so`。
+如果你将 `xdebug-zts.so` 移动到你的扩展目录中，添加 `zend_extension=xdebug-zts.so` 到你的 php.ini 并运行 FrankenPHP，它将加载 Xdebug。

+
+## 自定义应用程序
+
+以下示例展示了如何创建自己的 worker 脚本而不依赖第三方库：
+
+```php
+<?php
+// public/index.php
+
+// 防止客户端连接中断时 worker 脚本终止
+ignore_user_abort(true);
+
+// 启动你的应用程序
+require __DIR__.'/vendor/autoload.php';
+
+$myApp = new \App\Kernel();
+$myApp->boot();
+
+// 在循环外的处理器以获得更好的性能（减少工作量）
+$handler = static function () use ($myApp) {
+    // 当收到请求时调用，
+    // 超全局变量、php://input 等都会被重置
+    echo $myApp->handle($_GET, $_POST, $_COOKIE, $_FILES, $_SERVER);
+};
+
+$maxRequests = (int)($_SERVER['MAX_REQUESTS'] ?? 0);
+for ($nbRequests = 0; !$maxRequests || $nbRequests < $maxRequests; ++$nbRequests) {
+    $keepRunning = \frankenphp_handle_request($handler);
+
+    // 在发送 HTTP 响应后做一些事情
+    $myApp->terminate();
+
+    // 调用垃圾收集器以减少在页面生成过程中触发垃圾收集的可能性
+    gc_collect_cycles();
+
+    if (!$keepRunning) break;
+}
+
+// 清理
+$myApp->shutdown();
+```
+
+然后，启动你的应用程序并使用 `FRANKENPHP_CONFIG` 环境变量配置你的 worker：
+
+```console
+docker run \
+    -e FRANKENPHP_CONFIG="worker ./public/index.php" \
+    -v $PWD:/app \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+默认情况下，每个 CPU 启动 2 个 worker。
+你也可以配置要启动的 worker 数量：
+
+```console
+docker run \
+    -e FRANKENPHP_CONFIG="worker ./public/index.php 42" \
+    -v $PWD:/app \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+### 在处理一定数量的请求后重启 Worker
+
+由于 PHP 最初不是为长时间运行的进程而设计的，仍有许多库和传统代码会泄漏内存。
+在 worker 模式下使用此类代码的一个解决方法是在处理一定数量的请求后重启 worker 脚本：
+
+前面的 worker 代码片段允许通过设置名为 `MAX_REQUESTS` 的环境变量来配置要处理的最大请求数。
+
+### 手动重启 Workers
+
+虽然可以在[文件更改时重启 workers](config.md#watching-for-file-changes)，但也可以通过 [Caddy admin API](https://caddyserver.com/docs/api) 优雅地重启所有 workers。如果在你的 [Caddyfile](config.md#caddyfile-config) 中启用了 admin，你可以通过简单的 POST 请求 ping 重启端点，如下所示：
+
+```console
+curl -X POST http://localhost:2019/frankenphp/workers/restart
+```
+
+### Worker 故障
+
+如果 worker 脚本因非零退出代码而崩溃，FrankenPHP 将使用指数退避策略重启它。
+如果 worker 脚本保持运行的时间超过上次退避 × 2，
+它将不会惩罚 worker 脚本并再次重启它。
+但是，如果 worker 脚本在短时间内继续以非零退出代码失败
+（例如，脚本中有拼写错误），FrankenPHP 将崩溃并出现错误：`too many consecutive failures`。
+
+可以在你的 [Caddyfile](config.md#caddyfile-配置) 中使用 `max_consecutive_failures` 选项配置连续失败的次数：
+
+```caddyfile
+frankenphp {
+    worker {
+        # ...
+        max_consecutive_failures 10
+    }
+}
+```
+
+## 超全局变量行为
+
+[PHP 超全局变量](https://www.php.net/manual/zh/language.variables.superglobals.php)（`$_SERVER`、`$_ENV`、`$_GET`...）
+行为如下：
+
+- 在第一次调用 `frankenphp_handle_request()` 之前，超全局变量包含绑定到 worker 脚本本身的值
+- 在调用 `frankenphp_handle_request()` 期间和之后，超全局变量包含从处理的 HTTP 请求生成的值，每次调用 `frankenphp_handle_request()` 都会更改超全局变量的值
+
+要在回调内访问 worker 脚本的超全局变量，必须复制它们并将副本导入到回调的作用域中：
+
+```php
+<?php
+// 在第一次调用 frankenphp_handle_request() 之前复制 worker 的 $_SERVER 超全局变量
+$workerServer = $_SERVER;
+
+$handler = static function () use ($workerServer) {
+    var_dump($_SERVER); // 与请求绑定的 $_SERVER
+    var_dump($workerServer); // worker 脚本的 $_SERVER
+};
+
+// ...
+```

+# 高效服务大型静态文件 (`X-Sendfile`/`X-Accel-Redirect`)
+
+通常，静态文件可以直接由 Web 服务器提供服务，
+但有时在发送它们之前需要执行一些 PHP 代码：
+访问控制、统计、自定义 HTTP 头...
+
+不幸的是，与直接使用 Web 服务器相比，使用 PHP 服务大型静态文件效率低下
+（内存过载、性能降低...）。
+
+FrankenPHP 让你在执行自定义 PHP 代码**之后**将静态文件的发送委托给 Web 服务器。
+
+为此，你的 PHP 应用程序只需定义一个包含要服务的文件路径的自定义 HTTP 头。FrankenPHP 处理其余部分。
+
+此功能在 Apache 中称为 **`X-Sendfile`**，在 NGINX 中称为 **`X-Accel-Redirect`**。
+
+在以下示例中，我们假设项目的文档根目录是 `public/` 目录，
+并且我们想要使用 PHP 来服务存储在 `public/` 目录外的文件，
+来自名为 `private-files/` 的目录。
+
+## 配置
+
+首先，将以下配置添加到你的 `Caddyfile` 以启用此功能：
+
+```patch
+	root public/
+	# ...
+
++	# Symfony、Laravel 和其他使用 Symfony HttpFoundation 组件的项目需要
++	request_header X-Sendfile-Type x-accel-redirect
++	request_header X-Accel-Mapping ../private-files=/private-files
++
++	intercept {
++		@accel header X-Accel-Redirect *
++		handle_response @accel {
++			root private-files/
++			rewrite * {resp.header.X-Accel-Redirect}
++			method * GET
++
++			# 删除 PHP 设置的 X-Accel-Redirect 头以提高安全性
++			header -X-Accel-Redirect
++
++			file_server
++		}
++	}
+
+	php_server
+```
+
+## 纯 PHP
+
+将相对文件路径（从 `private-files/`）设置为 `X-Accel-Redirect` 头的值：
+
+```php
+header('X-Accel-Redirect: file.txt');
+```
+
+## 使用 Symfony HttpFoundation 组件的项目（Symfony、Laravel、Drupal...）
+
+Symfony HttpFoundation [原生支持此功能](https://symfony.com/doc/current/components/http_foundation.html#serving-files)。
+它将自动确定 `X-Accel-Redirect` 头的正确值并将其添加到响应中。
+
+```php
+use Symfony\Component\HttpFoundation\BinaryFileResponse;

+BinaryFileResponse::trustXSendfileTypeHeader();
+$response = new BinaryFileResponse(__DIR__.'/../private-files/file.txt');

 # Configuration
 
-FrankenPHP, Caddy as well as the Mercure and Vulcain modules can be configured using [the formats supported by Caddy](https://caddyserver.com/docs/getting-started#your-first-config).
+FrankenPHP, Caddy as well as the [Mercure](mercure.md) and [Vulcain](https://vulcain.rocks) modules can be configured using [the formats supported by Caddy](https://caddyserver.com/docs/getting-started#your-first-config).
 
-In the Docker image, the `Caddyfile` is located at `/etc/caddy/Caddyfile`.
+The most common format is the `Caddyfile`, which is a simple, human-readable text format.
+By default, FrankenPHP will look for a `Caddyfile` in the current directory.
+You can specify a custom path with the `-c` or `--config` option.
 
-You can also configure PHP using `php.ini` as usual.
+A minimal `Caddyfile` to serve a PHP application is shown below:
 
-In the Docker image, the `php.ini` file is not present, you can create it or `COPY` manually.
+```caddyfile
+# The hostname to respond to
+localhost
 
-If you copy `php.ini` from `$PHP_INI_DIR/php.ini-production` or `$PHP_INI_DIR/php.ini-development`, you also must set the variable `variables_order = "EGPCS"`, because the default value for `variables_order` is `"EGPCS"`, but in `php.ini-production` and `php.ini-development` we have `"GPCS"`. And in this case, `worker` does not work properly.
+# Optionaly, the directory to serve files from, otherwise defaults to the current directory
+#root public/
+php_server
+```
+
+A more advanced `Caddyfile` enabling more features and providing convenient environment variables is provided [in the FrankenPHP repository](https://github.com/php/frankenphp/blob/main/caddy/frankenphp/Caddyfile),
+and with Docker images.
+
+PHP itself can be configured [using a `php.ini` file](https://www.php.net/manual/en/configuration.file.php).
+
+Depending on your installation method, FrankenPHP and the PHP interpreter will look for configuration files in locations described below.
+
+## Docker

+### Watching for File Changes
+
+Since workers only boot your application once and keep it in memory, any changes
+to your PHP files will not be reflected immediately.
+
+Workers can instead be restarted on file changes via the `watch` directive.
+This is useful for development environments.

+	frankenphp {
+		worker {
+			file  /path/to/app/public/worker.php
+			watch
+		}
+	}

+
+If the `watch` directory is not specified, it will fall back to `./**/*.{php,yaml,yml,twig,env}`,
+which watches all `.php`, `.yaml`, `.yml`, `.twig` and `.env` files in the directory and subdirectories
+where the FrankenPHP process was started. You can instead also specify one or more directories via a
+[shell filename pattern](https://pkg.go.dev/path/filepath#Match):

+	frankenphp {
+		worker {

+- The `**` pattern signifies recursive watching
+- Directories can also be relative (to where the FrankenPHP process is started from)
+- If you have multiple workers defined, all of them will be restarted when a file changes
+- Be wary about watching files that are created at runtime (like logs) since they might cause unwanted worker restarts.
+
+The file watcher is based on [e-dant/watcher](https://github.com/e-dant/watcher).
+
+## Matching the worker to a path
+
+In traditional PHP applications, scripts are always placed in the public directory.
+This is also true for worker scripts, which are treated like any other PHP script.
+If you want to instead put the worker script outside the public directory, you can do so via the `match` directive.
+
+The `match` directive is an optimized alternative to `try_files` only available inside `php_server` and `php`.
+The following example will always serve a file in the public directory if present
+and otherwise forward the request to the worker matching the path pattern.
+
+```caddyfile
+{
+	frankenphp {
+		php_server {
+			worker {
+				file /path/to/worker.php # file can be outside of public path
+				match /api/* # all requests starting with /api/ will be handled by this worker
+			}
+		}
+	}
 }

+As for FPM and CLI SAPIs, environment variables are exposed by default in the `$_SERVER` superglobal.
 
-To propagate environment variables to `$_SERVER` and `$_ENV`, set the `php.ini` `variables_order` directive to `EGPCS`.

+
+To load [additional PHP configuration files](https://www.php.net/manual/en/configuration.file.php#configuration.file.scan),

+
+### Disabling HTTPS
+
+By default, FrankenPHP will automatically enable HTTPS using for all the hostnames, including `localhost`.
+If you want to disable HTTPS (for example in a development environment), you can set the `SERVER_NAME` environment variable to `http://` or `:80`:
+
+Alternatively, you can use all other methods described in the [Caddy documentation](https://caddyserver.com/docs/automatic-https#activation).

+
+### Full Duplex (HTTP/1)
+

+  }
+}

+
+> [!CAUTION]
+>
+> Enabling this option may cause old HTTP/1.x clients that don't support full-duplex to deadlock.
+> This can also be configured using the `CADDY_GLOBAL_OPTIONS` environment config:
+
+```sh
+CADDY_GLOBAL_OPTIONS="servers {

+# Writing PHP Extensions in Go
+
+With FrankenPHP, you can **write PHP extensions in Go**, which allows you to create **high-performance native functions** that can be called directly from PHP. Your applications can leverage any existing or new Go library, as well as the infamous concurrency model of **goroutines right from your PHP code**.
+
+Writing PHP extensions is typically done in C, but it's also possible to write them in other languages with a bit of extra work. PHP extensions allow you to leverage the power of low-level languages to extend PHP's functionalities, for example, by adding native functions or optimizing specific operations.
+
+Thanks to Caddy modules, you can write PHP extensions in Go and integrate them very quickly into FrankenPHP.
+
+## Two Approaches
+
+FrankenPHP provides two ways to create PHP extensions in Go:
+
+1. **Using the Extension Generator** - The recommended approach that generates all necessary boilerplate for most use cases, allowing you to focus on writing your Go code
+2. **Manual Implementation** - Full control over the extension structure for advanced use cases
+
+We'll start with the generator approach as it's the easiest way to get started, then show the manual implementation for those who need complete control.
+
+## Using the Extension Generator
+
+FrankenPHP is bundled with a tool that allows you **to create a PHP extension** only using Go. **No need to write C code** or use CGO directly: FrankenPHP also includes a **public types API** to help you write your extensions in Go without having to worry about **the type juggling between PHP/C and Go**.
+
+> [!TIP]
+> If you want to understand how extensions can be written in Go from scratch, you can read the manual implementation section below demonstrating how to write a PHP extension in Go without using the generator.
+
+Keep in mind that this tool is **not a full-fledged extension generator**. It is meant to help you write simple extensions in Go, but it does not provide the most advanced features of PHP extensions. If you need to write a more **complex and optimized** extension, you may need to write some C code or use CGO directly.
+
+### Prerequisites
+
+As covered in the manual implementation section below as well, you need to [get the PHP sources](https://www.php.net/downloads.php) and create a new Go module.
+
+#### Create a New Module and Get PHP Sources
+
+The first step to writing a PHP extension in Go is to create a new Go module. You can use the following command for this:
+
+```console
+go mod init example.com/example
+```
+
+The second step is to [get the PHP sources](https://www.php.net/downloads.php) for the next steps. Once you have them, decompress them into the directory of your choice, not inside your Go module:
+
+```console
+tar xf php-*
+```
+
+### Writing the Extension
+
+Everything is now setup to write your native function in Go. Create a new file named `stringext.go`. Our first function will take a string as an argument, the number of times to repeat it, a boolean to indicate whether to reverse the string, and return the resulting string. This should look like this:
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "strings"
+	"unsafe"
+
+	"github.com/dunglas/frankenphp"
+)
+
+//export_php:function repeat_this(string $str, int $count, bool $reverse): string
+func repeat_this(s *C.zend_string, count int64, reverse bool) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    result := strings.Repeat(str, int(count))
+    if reverse {
+        runes := []rune(result)
+        for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
+            runes[i], runes[j] = runes[j], runes[i]
+        }
+        result = string(runes)
+    }
+
+    return frankenphp.PHPString(result, false)
+}
+```
+
+There are two important things to note here:
+
+- A directive comment `//export_php:function` defines the function signature in PHP. This is how the generator knows how to generate the PHP function with the right parameters and return type;
+- The function must return an `unsafe.Pointer`. FrankenPHP provides an API to help you with type juggling between C and Go.
+
+While the first point speaks for itself, the second may be harder to apprehend. Let's take a deeper dive to type juggling in the next section.
+
+### Type Juggling
+
+While some variable types have the same memory representation between C/PHP and Go, some types require more logic to be directly used. This is maybe the hardest part when it comes to writing extensions because it requires understanding internals of the Zend Engine and how variables are stored internally in PHP.
+This table summarizes what you need to know:
+

+
+> [!NOTE]
+>
+> This table is not exhaustive yet and will be completed as the FrankenPHP types API gets more complete.
+>
+> For class methods specifically, primitive types and arrays are currently supported. Objects cannot be used as method parameters or return types yet.
+
+If you refer to the code snippet of the previous section, you can see that helpers are used to convert the first parameter and the return value. The second and third parameter of our `repeat_this()` function don't need to be converted as memory representation of the underlying types are the same for both C and Go.
+
+#### Working with Arrays
+
+FrankenPHP provides native support for PHP arrays through `frankenphp.AssociativeArray` or direct conversion to a map or slice.
+
+`AssociativeArray` represents a [hash map](https://en.wikipedia.org/wiki/Hash_table) composed of a `Map: map[string]any`field and an optional `Order: []string` field (unlike PHP "associative arrays", Go maps aren't ordered).
+
+If order or association are not needed, it's also possible to directly convert to a slice `[]any` or unordered map `map[string]any`.
+
+**Creating and manipulating arrays in Go:**
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+// export_php:function process_data_ordered(array $input): array
+func process_data_ordered_map(arr *C.zend_array) unsafe.Pointer {
+	// Convert PHP associative array to Go while keeping the order
+	associativeArray, err := frankenphp.GoAssociativeArray[any](unsafe.Pointer(arr))
+    if err != nil {
+        // handle error
+    }
+
+	// loop over the entries in order
+	for _, key := range associativeArray.Order {
+		value, _ = associativeArray.Map[key]
+		// do something with key and value
+	}
+
+	// return an ordered array
+	// if 'Order' is not empty, only the key-value pairs in 'Order' will be respected
+	return frankenphp.PHPAssociativeArray[string](frankenphp.AssociativeArray[string]{
+		Map: map[string]string{
+			"key1": "value1",
+			"key2": "value2",
+		},
+		Order: []string{"key1", "key2"},
+	})
+}
+
+// export_php:function process_data_unordered(array $input): array
+func process_data_unordered_map(arr *C.zend_array) unsafe.Pointer {
+	// Convert PHP associative array to a Go map without keeping the order
+	// ignoring the order will be more performant
+	goMap, err := frankenphp.GoMap[any](unsafe.Pointer(arr))
+    if err != nil {
+        // handle error
+    }
+
+	// loop over the entries in no specific order
+	for key, value := range goMap {
+		// do something with key and value
+	}
+
+	// return an unordered array
+	return frankenphp.PHPMap(map[string]string {
+		"key1": "value1",
+		"key2": "value2",
+	})
+}
+
+// export_php:function process_data_packed(array $input): array
+func process_data_packed(arr *C.zend_array) unsafe.Pointer {
+	// Convert PHP packed array to Go
+	goSlice, err := frankenphp.GoPackedArray(unsafe.Pointer(arr))
+    if err != nil {
+        // handle error
+    }
+
+	// loop over the slice in order
+	for index, value := range goSlice {
+		// do something with index and value
+	}
+
+	// return a packed array
+	return frankenphp.PHPPackedArray([]string{"value1", "value2", "value3"})
+}
+```
+
+**Key features of array conversion:**
+
+- **Ordered key-value pairs** - Option to keep the order of the associative array
+- **Optimized for multiple cases** - Option to ditch the order for better performance or convert straight to a slice
+- **Automatic list detection** - When converting to PHP, automatically detects if array should be a packed list or hashmap
+- **Nested Arrays** - Arrays can be nested and will convert all support types automatically (`int64`,`float64`,`string`,`bool`,`nil`,`AssociativeArray`,`map[string]any`,`[]any`)
+- **Objects are not supported** - Currently, only scalar types and arrays can be used as values. Providing an object will result in a `null` value in the PHP array.
+
+##### Available methods: Packed and Associative
+
+- `frankenphp.PHPAssociativeArray(arr frankenphp.AssociativeArray) unsafe.Pointer` - Convert to an ordered PHP array with key-value pairs
+- `frankenphp.PHPMap(arr map[string]any) unsafe.Pointer` - Convert a map to an unordered PHP array with key-value pairs
+- `frankenphp.PHPPackedArray(slice []any) unsafe.Pointer` - Convert a slice to a PHP packed array with indexed values only
+- `frankenphp.GoAssociativeArray(arr unsafe.Pointer, ordered bool) frankenphp.AssociativeArray` - Convert a PHP array to an ordered Go `AssociativeArray` (map with order)
+- `frankenphp.GoMap(arr unsafe.Pointer) map[string]any` - Convert a PHP array to an unordered Go map
+- `frankenphp.GoPackedArray(arr unsafe.Pointer) []any` - Convert a PHP array to a Go slice
+- `frankenphp.IsPacked(zval *C.zend_array) bool` - Check if a PHP array is packed (indexed only) or associative (key-value pairs)
+
+### Working with Callables
+
+FrankenPHP provides a way to work with PHP callables using the `frankenphp.CallPHPCallable` helper. This allows you to call PHP functions or methods from Go code.
+
+To showcase this, let's create our own `array_map()` function that takes a callable and an array, applies the callable to each element of the array, and returns a new array with the results:
+
+```go
+// export_php:function my_array_map(array $data, callable $callback): array
+func my_array_map(arr *C.zend_array, callback *C.zval) unsafe.Pointer {
+	goSlice, err := frankenphp.GoPackedArray[any](unsafe.Pointer(arr))
+	if err != nil {
+		panic(err)
+	}
+
+	result := make([]any, len(goSlice))
+
+	for index, value := range goSlice {
+		result[index] = frankenphp.CallPHPCallable(unsafe.Pointer(callback), []interface{}{value})
+	}
+
+	return frankenphp.PHPPackedArray(result)
+}
+```
+
+Notice how we use `frankenphp.CallPHPCallable()` to call the PHP callable passed as a parameter. This function takes a pointer to the callable and an array of arguments, and it returns the result of the callable execution. You can use the callable syntax you're used to:
+
+```php
+<?php
+
+$result = my_array_map([1, 2, 3], function($x) { return $x * 2; });
+// $result will be [2, 4, 6]
+
+$result = my_array_map(['hello', 'world'], 'strtoupper');
+// $result will be ['HELLO', 'WORLD']
+```
+
+### Declaring a Native PHP Class
+
+The generator supports declaring **opaque classes** as Go structs, which can be used to create PHP objects. You can use the `//export_php:class` directive comment to define a PHP class. For example:
+
+```go
+package example
+
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+```
+
+#### What are Opaque Classes?
+
+**Opaque classes** are classes where the internal structure (properties) is hidden from PHP code. This means:
+
+- **No direct property access**: You cannot read or write properties directly from PHP (`$user->name` won't work)
+- **Method-only interface** - All interactions must go through methods you define
+- **Better encapsulation** - Internal data structure is completely controlled by Go code
+- **Type safety** - No risk of PHP code corrupting internal state with wrong types
+- **Cleaner API** - Forces to design a proper public interface
+
+This approach provides better encapsulation and prevents PHP code from accidentally corrupting the internal state of your Go objects. All interactions with the object must go through the methods you explicitly define.
+
+#### Adding Methods to Classes
+
+Since properties are not directly accessible, you **must define methods** to interact with your opaque classes. Use the `//export_php:method` directive to define behavior:
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+
+//export_php:method User::getName(): string
+func (us *UserStruct) GetUserName() unsafe.Pointer {
+    return frankenphp.PHPString(us.Name, false)
+}
+
+//export_php:method User::setAge(int $age): void
+func (us *UserStruct) SetUserAge(age int64) {
+    us.Age = int(age)
+}
+
+//export_php:method User::getAge(): int
+func (us *UserStruct) GetUserAge() int64 {
+    return int64(us.Age)
+}
+
+//export_php:method User::setNamePrefix(string $prefix = "User"): void
+func (us *UserStruct) SetNamePrefix(prefix *C.zend_string) {
+    us.Name = frankenphp.GoString(unsafe.Pointer(prefix)) + ": " + us.Name
+}
+```
+
+#### Nullable Parameters
+
+The generator supports nullable parameters using the `?` prefix in PHP signatures. When a parameter is nullable, it becomes a pointer in your Go function, allowing you to check if the value was `null` in PHP:
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+	"unsafe"
+
+	"github.com/dunglas/frankenphp"
+)
+
+//export_php:method User::updateInfo(?string $name, ?int $age, ?bool $active): void
+func (us *UserStruct) UpdateInfo(name *C.zend_string, age *int64, active *bool) {
+    // Check if name was provided (not null)
+    if name != nil {
+        us.Name = frankenphp.GoString(unsafe.Pointer(name))
+    }
+
+    // Check if age was provided (not null)
+    if age != nil {
+        us.Age = int(*age)
+    }
+
+    // Check if active was provided (not null)
+    if active != nil {
+        us.Active = *active
+    }
+}
+```
+
+**Key points about nullable parameters:**
+
+- **Nullable primitive types** (`?int`, `?float`, `?bool`) become pointers (`*int64`, `*float64`, `*bool`) in Go
+- **Nullable strings** (`?string`) remain as `*C.zend_string` but can be `nil`
+- **Check for `nil`** before dereferencing pointer values
+- **PHP `null` becomes Go `nil`** - when PHP passes `null`, your Go function receives a `nil` pointer
+
+> [!WARNING]
+>
+> Currently, class methods have the following limitations. **Objects are not supported** as parameter types or return types. **Arrays are fully supported** for both parameters and return types. Supported types: `string`, `int`, `float`, `bool`, `array`, and `void` (for return type). **Nullable parameter types are fully supported** for all scalar types (`?string`, `?int`, `?float`, `?bool`).
+
+After generating the extension, you will be allowed to use the class and its methods in PHP. Note that you **cannot access properties directly**:
+
+```php
+<?php
+
+$user = new User();
+
+// ✅ This works - using methods
+$user->setAge(25);
+echo $user->getName();           // Output: (empty, default value)
+echo $user->getAge();            // Output: 25
+$user->setNamePrefix("Employee");
+
+// ✅ This also works - nullable parameters
+$user->updateInfo("John", 30, true);        // All parameters provided
+$user->updateInfo("Jane", null, false);     // Age is null
+$user->updateInfo(null, 25, null);          // Name and active are null
+
+// ❌ This will NOT work - direct property access
+// echo $user->name;             // Error: Cannot access private property
+// $user->age = 30;              // Error: Cannot access private property
+```
+
+This design ensures that your Go code has complete control over how the object's state is accessed and modified, providing better encapsulation and type safety.
+
+### Declaring Constants
+
+The generator supports exporting Go constants to PHP using two directives: `//export_php:const` for global constants and `//export_php:classconst` for class constants. This allows you to share configuration values, status codes, and other constants between Go and PHP code.
+
+#### Global Constants
+
+Use the `//export_php:const` directive to create global PHP constants:
+
+```go
+package example
+
+//export_php:const
+const MAX_CONNECTIONS = 100
+
+//export_php:const
+const API_VERSION = "1.2.3"
+
+//export_php:const
+const STATUS_OK = iota
+
+//export_php:const
+const STATUS_ERROR = iota
+```
+
+#### Class Constants
+
+Use the `//export_php:classconst ClassName` directive to create constants that belong to a specific PHP class:
+
+```go
+package example
+
+//export_php:classconst User
+const STATUS_ACTIVE = 1
+
+//export_php:classconst User
+const STATUS_INACTIVE = 0
+
+//export_php:classconst User
+const ROLE_ADMIN = "admin"
+
+//export_php:classconst Order
+const STATE_PENDING = iota
+
+//export_php:classconst Order
+const STATE_PROCESSING = iota
+
+//export_php:classconst Order
+const STATE_COMPLETED = iota
+```
+
+Class constants are accessible using the class name scope in PHP:
+
+```php
+<?php
+
+// Global constants
+echo MAX_CONNECTIONS;    // 100
+echo API_VERSION;        // "1.2.3"
+
+// Class constants
+echo User::STATUS_ACTIVE;    // 1
+echo User::ROLE_ADMIN;       // "admin"
+echo Order::STATE_PENDING;   // 0
+```
+
+The directive supports various value types including strings, integers, booleans, floats, and iota constants. When using `iota`, the generator automatically assigns sequential values (0, 1, 2, etc.). Global constants become available in your PHP code as global constants, while class constants are scoped to their respective classes using the public visibility. When using integers, different possible notation (binary, hex, octal) are supported and dumped as is in the PHP stub file.
+
+You can use constants just like you are used to in the Go code. For example, let's take the `repeat_this()` function we declared earlier and change the last argument to an integer:
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+	"strings"
+	"unsafe"
+
+	"github.com/dunglas/frankenphp"
+)
+
+//export_php:const
+const STR_REVERSE = iota
+
+//export_php:const
+const STR_NORMAL = iota
+
+//export_php:classconst StringProcessor
+const MODE_LOWERCASE = 1
+
+//export_php:classconst StringProcessor
+const MODE_UPPERCASE = 2
+
+//export_php:function repeat_this(string $str, int $count, int $mode): string
+func repeat_this(s *C.zend_string, count int64, mode int) unsafe.Pointer {
+	str := frankenphp.GoString(unsafe.Pointer(s))
+
+	result := strings.Repeat(str, int(count))
+	if mode == STR_REVERSE {
+		// reverse the string
+	}
+
+	if mode == STR_NORMAL {
+		// no-op, just to showcase the constant
+	}
+
+	return frankenphp.PHPString(result, false)
+}
+
+//export_php:class StringProcessor
+type StringProcessorStruct struct {
+	// internal fields
+}
+
+//export_php:method StringProcessor::process(string $input, int $mode): string
+func (sp *StringProcessorStruct) Process(input *C.zend_string, mode int64) unsafe.Pointer {
+	str := frankenphp.GoString(unsafe.Pointer(input))
+
+	switch mode {
+	case MODE_LOWERCASE:
+		str = strings.ToLower(str)
+	case MODE_UPPERCASE:
+		str = strings.ToUpper(str)
+	}
+
+	return frankenphp.PHPString(str, false)
+}
+```
+
+### Using Namespaces
+
+The generator supports organizing your PHP extension's functions, classes, and constants under a namespace using the `//export_php:namespace` directive. This helps avoid naming conflicts and provides better organization for your extension's API.
+
+#### Declaring a Namespace
+
+Use the `//export_php:namespace` directive at the top of your Go file to place all exported symbols under a specific namespace:
+
+```go
+//export_php:namespace My\Extension
+package example
+
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:function hello(): string
+func hello() string {
+    return "Hello from My\\Extension namespace!"
+}
+
+//export_php:class User
+type UserStruct struct {
+    // internal fields
+}
+
+//export_php:method User::getName(): string
+func (u *UserStruct) GetName() unsafe.Pointer {
+    return frankenphp.PHPString("John Doe", false)
+}
+
+//export_php:const
+const STATUS_ACTIVE = 1
+```
+
+#### Using Namespaced Extension in PHP
+
+When a namespace is declared, all functions, classes, and constants are placed under that namespace in PHP:
+
+```php
+<?php
+
+echo My\Extension\hello(); // "Hello from My\Extension namespace!"
+
+$user = new My\Extension\User();
+echo $user->getName(); // "John Doe"
+
+echo My\Extension\STATUS_ACTIVE; // 1
+```
+
+#### Important Notes
+
+- Only **one** namespace directive is allowed per file. If multiple namespace directives are found, the generator will return an error.
+- The namespace applies to **all** exported symbols in the file: functions, classes, methods, and constants.
+- Namespace names follow PHP namespace conventions using backslashes (`\`) as separators.
+- If no namespace is declared, symbols are exported to the global namespace as usual.
+
+### Generating the Extension
+
+This is where the magic happens, and your extension can now be generated. You can run the generator with the following command:
+
+```console
+GEN_STUB_SCRIPT=php-src/build/gen_stub.php frankenphp extension-init my_extension.go
+```
+
+> [!NOTE]
+> Don't forget to set the `GEN_STUB_SCRIPT` environment variable to the path of the `gen_stub.php` file in the PHP sources you downloaded earlier. This is the same `gen_stub.php` script mentioned in the manual implementation section.
+
+If everything went well, a new directory named `build` should have been created. This directory contains the generated files for your extension, including the `my_extension.go` file with the generated PHP function stubs.
+
+### Integrating the Generated Extension into FrankenPHP
+
+Our extension is now ready to be compiled and integrated into FrankenPHP. To do this, refer to the FrankenPHP [compilation documentation](compile.md) to learn how to compile FrankenPHP. Add the module using the `--with` flag, pointing to the path of your module:
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module/build
+```
+
+Note that you point to the `/build` subdirectory that was created during the generation step. However, this is not mandatory: you can also copy the generated files to your module directory and point to it directly.
+
+### Testing Your Generated Extension
+
+You can create a PHP file to test the functions and classes you've created. For example, create an `index.php` file with the following content:
+
+```php
+<?php
+
+// Using global constants
+var_dump(repeat_this('Hello World', 5, STR_REVERSE));
+
+// Using class constants
+$processor = new StringProcessor();
+echo $processor->process('Hello World', StringProcessor::MODE_LOWERCASE);  // "hello world"
+echo $processor->process('Hello World', StringProcessor::MODE_UPPERCASE);  // "HELLO WORLD"
+```
+
+Once you've integrated your extension into FrankenPHP as demonstrated in the previous section, you can run this test file using `./frankenphp php-server`, and you should see your extension working.
+
+## Manual Implementation
+
+If you want to understand how extensions work or need full control over your extension, you can write them manually. This approach gives you complete control but requires more boilerplate code.
+
+### Basic Function
+
+We'll see how to write a simple PHP extension in Go that defines a new native function. This function will be called from PHP and will trigger a goroutine that logs a message in Caddy's logs. This function doesn't take any parameters and returns nothing.
+
+#### Define the Go Function
+
+In your module, you need to define a new native function that will be called from PHP. To do this, create a file with the name you want, for example, `extension.go`, and add the following code:
+
+```go
+package example
+
+// #include "extension.h"
+import "C"
+import (
+	"log/slog"
+	"unsafe"
+
+	"github.com/dunglas/frankenphp"
+)
+
+func init() {
+	frankenphp.RegisterExtension(unsafe.Pointer(&C.ext_module_entry))
+}
+
+//export go_print_something
+func go_print_something() {
+	go func() {
+		slog.Info("Hello from a goroutine!")
+	}()
+}
+```
+
+The `frankenphp.RegisterExtension()` function simplifies the extension registration process by handling the internal PHP registration logic. The `go_print_something` function uses the `//export` directive to indicate that it will be accessible in the C code we will write, thanks to CGO.
+
+In this example, our new function will trigger a goroutine that logs a message in Caddy's logs.
+
+#### Define the PHP Function
+
+To allow PHP to call our function, we need to define a corresponding PHP function. For this, we will create a stub file, for example, `extension.stub.php`, which will contain the following code:
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+function go_print(): void {}
+```
+
+This file defines the signature of the `go_print()` function, which will be called from PHP. The `@generate-class-entries` directive allows PHP to automatically generate function entries for our extension.
+
+This is not done manually but using a script provided in the PHP sources (make sure to adjust the path to the `gen_stub.php` script based on where your PHP sources are located):
+
+```bash
+php ../php-src/build/gen_stub.php extension.stub.php
+```
+
+This script will generate a file named `extension_arginfo.h` that contains the necessary information for PHP to know how to define and call our function.
+
+#### Write the Bridge Between Go and C
+
+Now, we need to write the bridge between Go and C. Create a file named `extension.h` in your module directory with the following content:
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+Next, create a file named `extension.c` that will perform the following steps:
+
+- Include PHP headers;
+- Declare our new native PHP function `go_print()`;
+- Declare the extension metadata.
+
+Let's start by including the required headers:
+
+```c
+#include <php.h>
+#include "extension.h"
+#include "extension_arginfo.h"
+
+// Contains symbols exported by Go
+#include "_cgo_export.h"
+```
+
+We then define our PHP function as a native language function:
+
+```c
+PHP_FUNCTION(go_print)
+{
+    ZEND_PARSE_PARAMETERS_NONE();
+
+    go_print_something();
+}
+
+zend_module_entry ext_module_entry = {
+    STANDARD_MODULE_HEADER,
+    "ext_go",
+    ext_functions, /* Functions */
+    NULL,          /* MINIT */
+    NULL,          /* MSHUTDOWN */
+    NULL,          /* RINIT */
+    NULL,          /* RSHUTDOWN */
+    NULL,          /* MINFO */
+    "0.1.1",
+    STANDARD_MODULE_PROPERTIES
+};
+```
+
+In this case, our function takes no parameters and returns nothing. It simply calls the Go function we defined earlier, exported using the `//export` directive.
+
+Finally, we define the extension's metadata in a `zend_module_entry` structure, such as its name, version, and properties. This information is necessary for PHP to recognize and load our extension. Note that `ext_functions` is an array of pointers to the PHP functions we defined, and it was automatically generated by the `gen_stub.php` script in the `extension_arginfo.h` file.
+
+The extension registration is automatically handled by FrankenPHP's `RegisterExtension()` function that we call in our Go code.
+
+### Advanced Usage
+
+Now that we know how to create a basic PHP extension in Go, let's complexify our example. We will now create a PHP function that takes a string as a parameter and returns its uppercase version.
+
+#### Define the PHP Function Stub
+
+To define the new PHP function, we will modify our `extension.stub.php` file to include the new function signature:
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+/**
+ * Converts a string to uppercase.
+ *
+ * @param string $string The string to convert.
+ * @return string The uppercase version of the string.
+ */
+function go_upper(string $string): string {}
+```
+
+> [!TIP]
+> Don't neglect the documentation of your functions! You are likely to share your extension stubs with other developers to document how to use your extension and which features are available.
+
+By regenerating the stub file with the `gen_stub.php` script, the `extension_arginfo.h` file should look like this:
+
+```c
+ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(arginfo_go_upper, 0, 1, IS_STRING, 0)
+    ZEND_ARG_TYPE_INFO(0, string, IS_STRING, 0)
+ZEND_END_ARG_INFO()
+
+ZEND_FUNCTION(go_upper);
+
+static const zend_function_entry ext_functions[] = {
+    ZEND_FE(go_upper, arginfo_go_upper)
+    ZEND_FE_END
+};
+```
+
+We can see that the `go_upper` function is defined with a parameter of type `string` and a return type of `string`.
+
+#### Type Juggling Between Go and PHP/C
+
+Your Go function cannot directly accept a PHP string as a parameter. You need to convert it to a Go string. Fortunately, FrankenPHP provides helper functions to handle the conversion between PHP strings and Go strings, similar to what we saw in the generator approach.
+
+The header file remains simple:
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+We can now write the bridge between Go and C in our `extension.c` file. We will pass the PHP string directly to our Go function:
+
+```c
+PHP_FUNCTION(go_upper)
+{
+    zend_string *str;
+
+    ZEND_PARSE_PARAMETERS_START(1, 1)
+        Z_PARAM_STR(str)
+    ZEND_PARSE_PARAMETERS_END();
+
+    zend_string *result = go_upper(str);
+    RETVAL_STR(result);
+}
+```
+
+You can learn more about the `ZEND_PARSE_PARAMETERS_START` and parameters parsing in the dedicated page of [the PHP Internals Book](https://www.phpinternalsbook.com/php7/extensions_design/php_functions.html#parsing-parameters-zend-parse-parameters). Here, we tell PHP that our function takes one mandatory parameter of type `string` as a `zend_string`. We then pass this string directly to our Go function and return the result using `RETVAL_STR`.
+
+There's only one thing left to do: implement the `go_upper` function in Go.
+
+#### Implement the Go Function
+
+Our Go function will take a `*C.zend_string` as a parameter, convert it to a Go string using FrankenPHP's helper function, process it, and return the result as a new `*C.zend_string`. The helper functions handle all the memory management and conversion complexity for us.
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+    "strings"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export go_upper
+func go_upper(s *C.zend_string) *C.zend_string {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    upper := strings.ToUpper(str)
+
+    return (*C.zend_string)(frankenphp.PHPString(upper, false))
+}
+```
+
+This approach is much cleaner and safer than manual memory management.
+FrankenPHP's helper functions handle the conversion between PHP's `zend_string` format and Go strings automatically.
+The `false` parameter in `PHPString()` indicates that we want to create a new non-persistent string (freed at the end of the request).
+
+> [!TIP]
+>
+> In this example, we don't perform any error handling, but you should always check that pointers are not `nil` and that the data is valid before using it in your Go functions.
+
+### Integrating the Extension into FrankenPHP
+
+Our extension is now ready to be compiled and integrated into FrankenPHP. To do this, refer to the FrankenPHP [compilation documentation](compile.md) to learn how to compile FrankenPHP. Add the module using the `--with` flag, pointing to the path of your module:
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module
+```
+
+That's it! Your extension is now integrated into FrankenPHP and can be used in your PHP code.
+
+### Testing Your Extension
+
+After integrating your extension into FrankenPHP, you can create an `index.php` file with examples for the functions you've implemented:
+
+```php
+<?php
+
+// Test basic function
+go_print();
+
+// Test advanced function
+echo go_upper("hello world") . "\n";
+```
+
+You can now run FrankenPHP with this file using `./frankenphp php-server`, and you should see your extension working.

+# Utilisation du mode classique
+
+Sans aucune configuration additionnelle, FrankenPHP fonctionne en mode classique. Dans ce mode, FrankenPHP fonctionne comme un serveur PHP traditionnel, en servant directement les fichiers PHP. Cela en fait un remplaçant parfait à PHP-FPM ou Apache avec mod_php.
+
+Comme Caddy, FrankenPHP accepte un nombre illimité de connexions et utilise un [nombre fixe de threads](config.md#configuration-du-caddyfile) pour les servir. Le nombre de connexions acceptées et en attente n'est limité que par les ressources système disponibles.
+Le pool de threads PHP fonctionne avec un nombre fixe de threads initialisés au démarrage, comparable au mode statique de PHP-FPM. Il est également possible de laisser les threads [s'adapter automatiquement à l'exécution](performance.md#max_threads), comme dans le mode dynamique de PHP-FPM.
+
+Les connexions en file d'attente attendront indéfiniment jusqu'à ce qu'un thread PHP soit disponible pour les servir. Pour éviter cela, vous pouvez utiliser la [configuration](config.md#configuration-du-caddyfile) `max_wait_time` dans la configuration globale de FrankenPHP pour limiter la durée pendant laquelle une requête peut attendre un thread PHP libre avant d'être rejetée.
+En outre, vous pouvez définir un [délai d'écriture dans Caddy](https://caddyserver.com/docs/caddyfile/options#timeouts) raisonnable.
+
+Chaque instance de Caddy n'utilisera qu'un seul pool de threads FrankenPHP, qui sera partagé par tous les blocs `php_server`.

+# Compiler depuis les sources
+
+Ce document explique comment créer un build FrankenPHP qui chargera PHP en tant que bibliothèque dynamique.
+C'est la méthode recommandée.
+
+Alternativement, il est aussi possible de [créer des builds statiques](static.md).
+
+## Installer PHP
+
+FrankenPHP est compatible avec PHP 8.2 et versions ultérieures.
+
+### Avec Homebrew (Linux et Mac)
+
+La manière la plus simple d'installer une version de libphp compatible avec FrankenPHP est d'utiliser les paquets ZTS fournis par [Homebrew PHP](https://github.com/shivammathur/homebrew-php).
+
+Tout d'abord, si ce n'est déjà fait, installez [Homebrew](https://brew.sh).
+
+Ensuite, installez la variante ZTS de PHP, Brotli (facultatif, pour la prise en charge de la compression) et watcher (facultatif, pour la détection des modifications de fichiers) :
+
+```console
+brew install shivammathur/php/php-zts brotli watcher
+brew link --overwrite --force shivammathur/php/php-zts
+```
+
+### En compilant PHP
+
+Vous pouvez également compiler PHP à partir des sources avec les options requises par FrankenPHP en suivant ces étapes.
+
+Tout d'abord, [téléchargez les sources de PHP](https://www.php.net/downloads.php) et extrayez-les :
+
+```console
+tar xf php-*
+cd php-*/
+```
+
+Ensuite, configurez PHP pour votre système d'exploitation.
+
+Les options de configuration suivantes sont nécessaires pour la compilation, mais vous pouvez également inclure d'autres options selon vos besoins, par exemple pour ajouter des extensions et fonctionnalités supplémentaires.
+
+### Linux
+
+```console
+./configure \
+    --enable-embed \
+    --enable-zts \
+    --disable-zend-signals \
+    --enable-zend-max-execution-timers
+```
+
+### Mac
+
+Utilisez le gestionnaire de paquets [Homebrew](https://brew.sh/) pour installer les dépendances obligatoires et optionnelles :
+
+```console
+brew install libiconv bison brotli re2c pkg-config watcher
+echo 'export PATH="/opt/homebrew/opt/bison/bin:$PATH"' >> ~/.zshrc
+```
+
+Puis exécutez le script de configuration :
+
+```console
+./configure \
+    --enable-embed \
+    --enable-zts \
+    --disable-zend-signals \
+    --disable-opcache-jit \
+    --with-iconv=/opt/homebrew/opt/libiconv/
+```
+
+### Compilez PHP
+
+Finalement, compilez et installez PHP :
+
+```console
+make -j"$(getconf _NPROCESSORS_ONLN)"
+sudo make install
+```
+
+## Installez les dépendances optionnelles
+
+Certaines fonctionnalités de FrankenPHP nécessitent des dépendances optionnelles qui doivent être installées.
+Ces fonctionnalités peuvent également être désactivées en passant des tags de compilation au compilateur Go.
+
+| Fonctionnalité                                          | Dépendance                                                            | Tag de compilation pour la désactiver |
+| ------------------------------------------------------- | --------------------------------------------------------------------- | ------------------------------------- |
+| Compression Brotli                                      | [Brotli](https://github.com/google/brotli)                            | nobrotli                              |
+| Redémarrage des workers en cas de changement de fichier | [Watcher C](https://github.com/e-dant/watcher/tree/release/watcher-c) | nowatcher                             |
+
+## Compiler l'application Go
+
+### Utiliser xcaddy
+
+La méthode recommandée consiste à utiliser [xcaddy](https://github.com/caddyserver/xcaddy) pour compiler FrankenPHP.
+`xcaddy` permet également d'ajouter facilement des [modules Caddy personnalisés](https://caddyserver.com/docs/modules/) et des extensions FrankenPHP :
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/dunglas/frankenphp/caddy \
+    --with github.com/dunglas/caddy-cbrotli \
+    --with github.com/dunglas/mercure/caddy \
+    --with github.com/dunglas/vulcain/caddy
+    # Ajoutez les modules Caddy supplémentaires et les extensions FrankenPHP ici
+```
+
+> [!TIP]
+>
+> Si vous utilisez musl libc (la bibliothèque par défaut sur Alpine Linux) et Symfony,
+> vous pourriez avoir besoin d'augmenter la taille par défaut de la pile.
+> Sinon, vous pourriez rencontrer des erreurs telles que `PHP Fatal error: Maximum call stack size of 83360 bytes reached during compilation. Try splitting expression`
+>
+> Pour ce faire, modifiez la variable d'environnement `XCADDY_GO_BUILD_FLAGS` en quelque chose comme
+> `XCADDY_GO_BUILD_FLAGS=$'-ldflags "-w -s -extldflags \'-Wl,-z,stack-size=0x80000\'"'`
+> (modifiez la valeur de la taille de la pile selon les besoins de votre application).
+
+### Sans xcaddy
+
+Il est également possible de compiler FrankenPHP sans `xcaddy` en utilisant directement la commande `go` :
+
+```console
+curl -L https://github.com/php/frankenphp/archive/refs/heads/main.tar.gz | tar xz
+cd frankenphp-main/caddy/frankenphp
+CGO_CFLAGS=$(php-config --includes) CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" go build -tags=nobadger,nomysql,nopgx

+# Configuration
+
+FrankenPHP, Caddy ainsi que les modules Mercure et Vulcain peuvent être configurés en utilisant [les formats pris en charge par Caddy](https://caddyserver.com/docs/getting-started#your-first-config).
+
+Dans [les images Docker](docker.md), le `Caddyfile` est situé dans `/etc/frankenphp/Caddyfile`.
+Le binaire statique cherchera le `Caddyfile` dans le répertoire dans lequel il est démarré.
+
+PHP lui-même peut être configuré [en utilisant un fichier `php.ini`](https://www.php.net/manual/fr/configuration.file.php).
+
+L'interpréteur PHP cherchera dans les emplacements suivants :
+
+Docker :
+
+- php.ini : `/usr/local/etc/php/php.ini` Aucun php.ini n'est fourni par défaut.
+- fichiers de configuration supplémentaires : `/usr/local/etc/php/conf.d/*.ini`
+- extensions php : `/usr/local/lib/php/extensions/no-debug-zts-<YYYYMMDD>/`
+- Vous devriez copier un modèle officiel fourni par le projet PHP :
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# Production :
+RUN cp $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini
+
+# Ou développement :
+RUN cp $PHP_INI_DIR/php.ini-development $PHP_INI_DIR/php.ini
+```
+
+Installation de FrankenPHP (.rpm ou .deb) :
+
+- php.ini : `/etc/frankenphp/php.ini` Un fichier php.ini avec des préréglages de production est fourni par défaut.
+- fichiers de configuration supplémentaires : `/etc/frankenphp/php.d/*.ini`
+- extensions php : `/usr/lib/frankenphp/modules/`
+
+Binaire statique :
+
+- php.ini : Le répertoire dans lequel `frankenphp run` ou `frankenphp php-server` est exécuté, puis `/etc/frankenphp/php.ini`
+- fichiers de configuration supplémentaires : `/etc/frankenphp/php.d/*.ini`
+- extensions php : ne peuvent pas être chargées
+- copiez l'un des fichiers `php.ini-production` ou `php.ini-development` fournis [dans les sources de PHP](https://github.com/php/php-src/).
+
+## Configuration du Caddyfile
+
+Les [directives HTTP](https://caddyserver.com/docs/caddyfile/concepts#directives) `php_server` ou `php` peuvent être utilisées dans les blocs de site pour servir votre application PHP.
+
+Exemple minimal :
+
+```caddyfile
+localhost {
+    # Activer la compression (optionnel)
+    encode zstd br gzip
+    # Exécuter les fichiers PHP dans le répertoire courant et servir les assets
+    php_server
+}
+```
+
+Vous pouvez également configurer explicitement FrankenPHP en utilisant l'option globale :
+L'[option globale](https://caddyserver.com/docs/caddyfile/concepts#global-options) `frankenphp` peut être utilisée pour configurer FrankenPHP.
+
+```caddyfile
+{
+    frankenphp {
+        num_threads <num_threads> # Définit le nombre de threads PHP à démarrer. Par défaut : 2x le nombre de CPUs disponibles.
+        max_threads <num_threads> # Limite le nombre de threads PHP supplémentaires qui peuvent être démarrés au moment de l'exécution. Valeur par défaut : num_threads. Peut être mis à 'auto'.
+        max_wait_time <duration> # Définit le temps maximum pendant lequel une requête peut attendre un thread PHP libre avant d'être interrompue. Valeur par défaut : désactivé.
+        php_ini <key> <value> Définit une directive php.ini. Peut être utilisé plusieurs fois pour définir plusieurs directives.
+        worker {
+            file <path> # Définit le chemin vers le script worker.
+            num <num> # Définit le nombre de threads PHP à démarrer, par défaut 2x le nombre de CPUs disponibles.
+            env <key> <value> # Définit une variable d'environnement supplémentaire avec la valeur donnée. Peut être spécifié plusieurs fois pour régler plusieurs variables d'environnement.
+            watch <path> # Définit le chemin d'accès à surveiller pour les modifications de fichiers. Peut être spécifié plusieurs fois pour plusieurs chemins.
+            name <name> # Définit le nom du worker, utilisé dans les journaux et les métriques. Défaut : chemin absolu du fichier du worker
+            max_consecutive_failures <num> # Définit le nombre maximum d'échecs consécutifs avant que le worker ne soit considéré comme défaillant, -1 signifie que le worker redémarre toujours. Par défaut : 6.
+        }
+    }
+}
+
+# ...
+```
+
+Vous pouvez également utiliser la forme courte de l'option worker en une seule ligne :
+
+```caddyfile
+{
+    frankenphp {
+        worker <file> <num>
+    }
+}
+
+# ...
+```
+
+Vous pouvez aussi définir plusieurs workers si vous servez plusieurs applications sur le même serveur :
+
+```caddyfile
+app.example.com {
+    root /path/to/app/public
+    php_server {
+        root /path/to/app/public # permet une meilleure mise en cache
+        worker index.php <num>
+    }
+}
+
+other.example.com {
+    root /path/to/other/public
+    php_server {
+        root /path/to/other/public
+        worker index.php <num>
+    }
+}
+
+# ...
+```
+
+L'utilisation de la directive `php_server` est généralement suffisante,
+mais si vous avez besoin d'un contrôle total, vous pouvez utiliser la directive `php`, qui permet un plus grand niveau de finesse dans la configuration.
+La directive `php` transmet toutes les entrées à PHP, au lieu de vérifier d'abord si
+c'est un fichier PHP ou pas. En savoir plus à ce sujet dans la [page performances](performance.md#try_files).
+
+Utiliser la directive `php_server` est équivalent à cette configuration :
+
+```caddyfile
+route {
+    # Ajoute un slash final pour les requêtes de répertoire
+    @canonicalPath {
+        file {path}/index.php
+        not path */
+    }
+    redir @canonicalPath {path}/ 308
+    # Si le fichier demandé n'existe pas, essayer les fichiers index
+    @indexFiles file {
+        try_files {path} {path}/index.php index.php
+        split_path .php
+    }
+    rewrite @indexFiles {http.matchers.file.relative}
+    # FrankenPHP!
+    @phpFiles path *.php
+    php @phpFiles
+    file_server
+}
+```
+
+Les directives `php_server` et `php` disposent des options suivantes :
+
+```caddyfile
+php_server [<matcher>] {
+    root <directory> # Définit le dossier racine du le site. Par défaut : valeur de la directive `root` parente.
+    split_path <delim...> # Définit les sous-chaînes pour diviser l'URI en deux parties. La première sous-chaîne correspondante sera utilisée pour séparer le "path info" du chemin. La première partie est suffixée avec la sous-chaîne correspondante et sera considérée comme le nom réel de la ressource (script CGI). La seconde partie sera définie comme PATH_INFO pour utilisation par le script. Par défaut : `.php`
+    resolve_root_symlink false # Désactive la résolution du répertoire `root` vers sa valeur réelle en évaluant un lien symbolique, s'il existe (activé par défaut).
+    env <key> <value> # Définit une variable d'environnement supplémentaire avec la valeur donnée. Peut être spécifié plusieurs fois pour plusieurs variables d'environnement.
+    file_server off # Désactive la directive file_server intégrée.
+    worker { # Crée un worker spécifique à ce serveur. Peut être spécifié plusieurs fois pour plusieurs workers.
+        file <path> # Définit le chemin vers le script worker, peut être relatif à la racine du php_server
+        num <num> # Définit le nombre de threads PHP à démarrer, par défaut 2x le nombre de CPUs disponibles
+        name <name> # Définit le nom du worker, utilisé dans les journaux et les métriques. Défaut : chemin absolu du fichier du worker. Commence toujours par m# lorsqu'il est défini dans un bloc php_server.
+        watch <path> # Définit le chemin d'accès à surveiller pour les modifications de fichiers. Peut être spécifié plusieurs fois pour plusieurs chemins.
+        env <key> <value> # Définit une variable d'environnement supplémentaire avec la valeur donnée. Peut être spécifié plusieurs fois pour plusieurs variables d'environnement. Les variables d'environnement pour ce worker sont également héritées du parent php_server, mais peuvent être écrasées ici.
+    }
+    worker <other_file> <num> # Peut également utiliser la forme courte comme dans le bloc frankenphp global.
+}
+```
+
+### Surveillance des modifications de fichier
+
+Vu que les workers ne démarrent votre application qu'une seule fois et la gardent en mémoire, toute modification
+apportée à vos fichiers PHP ne sera pas répercutée immédiatement.
+
+Les workers peuvent être redémarrés en cas de changement de fichier via la directive `watch`.
+Ceci est utile pour les environnements de développement.
+
+```caddyfile
+{
+	frankenphp {
+		worker {
+			file  /path/to/app/public/worker.php
+			watch
+		}
+	}
+}
+```
+
+Si le répertoire `watch` n'est pas précisé, il se rabattra sur `./**/*.{php,yaml,yml,twig,env}`,
+qui surveille tous les fichiers `.php`, `.yaml`, `.yml`, `.twig` et `.env` dans le répertoire et les sous-répertoires
+où le processus FrankenPHP a été lancé. Vous pouvez également spécifier un ou plusieurs répertoires via une commande
+[motif de nom de fichier shell](https://pkg.go.dev/path/filepath#Match) :
+
+```caddyfile
+{
+	frankenphp {
+		worker {
+			file  /path/to/app/public/worker.php
+			watch /path/to/app # surveille tous les fichiers dans tous les sous-répertoires de /path/to/app
+			watch /path/to/app/*.php # surveille les fichiers se terminant par .php dans /path/to/app
+			watch /path/to/app/**/*.php # surveille les fichiers PHP dans /path/to/app et les sous-répertoires
+			watch /path/to/app/**/*.{php,twig} # surveille les fichiers PHP et Twig dans /path/to/app et les sous-répertoires
+		}
+	}
+}
+```
+
+- Le motif `**` signifie une surveillance récursive.
+- Les répertoires peuvent également être relatifs (depuis l'endroit où le processus FrankenPHP est démarré).
+- Si vous avez défini plusieurs workers, ils seront tous redémarrés lorsqu'un fichier est modifié.
+- Méfiez-vous des fichiers créés au moment de l'exécution (comme les logs) car ils peuvent provoquer des redémarrages intempestifs du worker.
+
+La surveillance des fichiers est basé sur [e-dant/watcher](https://github.com/e-dant/watcher).
+
+### Full Duplex (HTTP/1)
+
+Lors de l'utilisation de HTTP/1.x, il peut être souhaitable d'activer le mode full-duplex pour permettre l'écriture d'une réponse avant que le corps entier
+n'ait été lu. (par exemple : WebSocket, événements envoyés par le serveur, etc.)
+
+Il s'agit d'une configuration optionnelle qui doit être ajoutée aux options globales dans le fichier `Caddyfile` :
+
+```caddyfile
+{
+    servers {
+        enable_full_duplex
+    }
+}
+```
+
+> [!CAUTION]
+>
+> L'activation de cette option peut entraîner un blocage (deadlock) des anciens clients HTTP/1.x qui ne supportent pas le full-duplex.
+> Cela peut aussi être configuré en utilisant la variable d'environnement `CADDY_GLOBAL_OPTIONS` :
+
+```sh
+CADDY_GLOBAL_OPTIONS="servers {
+  enable_full_duplex
+}"
+```
+
+Vous trouverez plus d'informations sur ce paramètre dans la [documentation Caddy](https://caddyserver.com/docs/caddyfile/options#enable-full-duplex).
+
+## Variables d'environnement
+
+Les variables d'environnement suivantes peuvent être utilisées pour insérer des directives Caddy dans le `Caddyfile` sans le modifier :
+
+- `SERVER_NAME` : change [les adresses sur lesquelles écouter](https://caddyserver.com/docs/caddyfile/concepts#addresses), les noms d'hôte fournis seront également utilisés pour le certificat TLS généré
+- `SERVER_ROOT` : change le répertoire racine du site, par défaut `public/`
+- `CADDY_GLOBAL_OPTIONS` : injecte [des options globales](https://caddyserver.com/docs/caddyfile/options)
+- `FRANKENPHP_CONFIG` : insère la configuration sous la directive `frankenphp`
+
+Comme pour les SAPI FPM et CLI, les variables d'environnement ne sont exposées par défaut dans la superglobale `$_SERVER`.
+
+La valeur `S` de [la directive `variables_order` de PHP](https://www.php.net/manual/fr/ini.core.php#ini.variables-order) est toujours équivalente à `ES`, que `E` soit défini ailleurs dans cette directive ou non.
+
+## Configuration PHP
+
+Pour charger [des fichiers de configuration PHP supplémentaires](https://www.php.net/manual/fr/configuration.file.php#configuration.file.scan),
+la variable d'environnement `PHP_INI_SCAN_DIR` peut être utilisée.
+Lorsqu'elle est définie, PHP chargera tous les fichiers avec l'extension `.ini` présents dans les répertoires donnés.
+
+Vous pouvez également modifier la configuration de PHP en utilisant la directive `php_ini` dans le fichier `Caddyfile` :
+
+```caddyfile
+{
+    frankenphp {
+        php_ini memory_limit 256M
+
+        # or
+
+        php_ini {
+            memory_limit 256M
+            max_execution_time 15
+        }
+    }
+}
+```
+
+## Activer le mode debug
+
+Lors de l'utilisation de l'image Docker, définissez la variable d'environnement `CADDY_GLOBAL_OPTIONS` sur `debug` pour activer le mode debug :
+
+```console
+docker run -v $PWD:/app/public \
+    -e CADDY_GLOBAL_OPTIONS=debug \
+    -p 80:80 -p 443:443 -p 443:443/udp \

+# Création d'une image Docker personnalisée
+
+Les images Docker de [FrankenPHP](https://hub.docker.com/r/dunglas/frankenphp) sont basées sur les [images PHP officielles](https://hub.docker.com/_/php/). Des variantes Debian et Alpine Linux sont fournies pour les architectures populaires. Les variantes Debian sont recommandées.
+
+Des variantes pour PHP 8.2, 8.3, 8.4 et 8.5 sont disponibles. [Parcourir les tags](https://hub.docker.com/r/dunglas/frankenphp/tags).
+
+Les tags suivent le pattern suivant: `dunglas/frankenphp:<frankenphp-version>-php<php-version>-<os>`
+
+- `<frankenphp-version>` et `<php-version>` sont repsectivement les numéros de version de FrankenPHP et PHP, allant de majeur (e.g. `1`), mineur (e.g. `1.2`) à des versions correctives (e.g. `1.2.3`).
+- `<os>` est soit `trixie` (pour Debian Trixie), `bookworm` (pour Debian Bookworm) ou `alpine` (pour la dernière version stable d'Alpine).
+
+[Parcourir les tags](https://hub.docker.com/r/dunglas/frankenphp/tags).
+
+## Comment utiliser les images
+
+Créez un `Dockerfile` dans votre projet :
+
+```dockerfile
+FROM dunglas/frankenphp
+
+COPY . /app/public
+```
+
+Ensuite, exécutez ces commandes pour construire et exécuter l'image Docker :
+
+```console
+docker build -t my-php-app .
+docker run -it --rm --name my-running-app my-php-app
+```
+
+## Comment installer plus d'extensions PHP
+
+Le script [`docker-php-extension-installer`](https://github.com/mlocati/docker-php-extension-installer) est fourni dans l'image de base.
+Il est facile d'ajouter des extensions PHP supplémentaires :
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# ajoutez des extensions supplémentaires ici :
+RUN install-php-extensions \
+	pdo_mysql \
+	gd \
+	intl \
+	zip \
+	opcache
+```
+
+## Comment installer plus de modules Caddy
+
+FrankenPHP est construit sur Caddy, et tous les [modules Caddy](https://caddyserver.com/docs/modules/) peuvent être utilisés avec FrankenPHP.
+
+La manière la plus simple d'installer des modules Caddy personnalisés est d'utiliser [xcaddy](https://github.com/caddyserver/xcaddy) :
+
+```dockerfile
+FROM dunglas/frankenphp:builder AS builder
+
+# Copier xcaddy dans l'image du constructeur
+COPY --from=caddy:builder /usr/bin/xcaddy /usr/bin/xcaddy
+
+# CGO doit être activé pour construire FrankenPHP
+RUN CGO_ENABLED=1 \
+    XCADDY_SETCAP=1 \
+    XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+    CGO_CFLAGS=$(php-config --includes) \
+    CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+    xcaddy build \
+        --output /usr/local/bin/frankenphp \
+        --with github.com/dunglas/frankenphp=./ \
+        --with github.com/dunglas/frankenphp/caddy=./caddy/ \
+        --with github.com/dunglas/caddy-cbrotli \
+        # Mercure et Vulcain sont inclus dans la construction officielle, mais n'hésitez pas à les retirer
+        --with github.com/dunglas/mercure/caddy \
+        --with github.com/dunglas/vulcain/caddy
+        # Ajoutez des modules Caddy supplémentaires ici
+
+FROM dunglas/frankenphp AS runner
+
+# Remplacer le binaire officiel par celui contenant vos modules personnalisés
+COPY --from=builder /usr/local/bin/frankenphp /usr/local/bin/frankenphp
+```
+
+L'image builder fournie par FrankenPHP contient une version compilée de `libphp`.
+[Les images builder](https://hub.docker.com/r/dunglas/frankenphp/tags?name=builder) sont fournies pour toutes les versions de FrankenPHP et PHP, à la fois pour Debian et Alpine.
+
+> [!TIP]
+>
+> Si vous utilisez Alpine Linux et Symfony,
+> vous devrez peut-être [augmenter la taille de pile par défaut](compile.md#utiliser-xcaddy).
+
+## Activer le mode Worker par défaut
+
+Définissez la variable d'environnement `FRANKENPHP_CONFIG` pour démarrer FrankenPHP avec un script worker :
+
+```dockerfile
+FROM dunglas/frankenphp
+
+# ...
+
+ENV FRANKENPHP_CONFIG="worker ./public/index.php"
+```
+
+## Utiliser un volume en développement
+
+Pour développer facilement avec FrankenPHP, montez le répertoire de l'hôte contenant le code source de l'application comme un volume dans le conteneur Docker :
+
+```console
+docker run -v $PWD:/app/public -p 80:80 -p 443:443 -p 443:443/udp --tty my-php-app
+```
+
+> [!TIP]
+>
+> L'option --tty permet d'avoir des logs lisibles par un humain au lieu de logs JSON.
+
+Avec Docker Compose :
+
+```yaml
+# compose.yaml
+
+services:
+  php:
+    image: dunglas/frankenphp
+    # décommentez la ligne suivante si vous souhaitez utiliser un Dockerfile personnalisé
+    #build: .
+    # décommentez la ligne suivante si vous souhaitez exécuter ceci dans un environnement de production
+    # restart: always
+    ports:
+      - "80:80" # HTTP
+      - "443:443" # HTTPS
+      - "443:443/udp" # HTTP/3
+    volumes:
+      - ./:/app/public
+      - caddy_data:/data
+      - caddy_config:/config
+    # commentez la ligne suivante en production, elle permet d'avoir de beaux logs lisibles en dev
+    tty: true
+
+# Volumes nécessaires pour les certificats et la configuration de Caddy
+volumes:
+  caddy_data:
+  caddy_config:
+```
+
+## Exécution en tant qu'utilisateur non-root
+
+FrankenPHP peut s'exécuter en tant qu'utilisateur non-root dans Docker.
+
+Voici un exemple de `Dockerfile` le permettant :
+
+```dockerfile
+FROM dunglas/frankenphp
+
+ARG USER=appuser
+
+RUN \
+	# Utilisez "adduser -D ${USER}" pour les distributions basées sur Alpine
+	useradd ${USER}; \
+	# Ajouter la capacité supplémentaire de se lier aux ports 80 et 443
+	setcap CAP_NET_BIND_SERVICE=+eip /usr/local/bin/frankenphp; \
+	# Donner l'accès en écriture à /data/caddy et /config/caddy
+	chown -R ${USER}:${USER} /data/caddy && chown -R ${USER}:${USER} /config/caddy
+
+USER ${USER}
+```
+
+### Exécution sans capacité
+
+Même lorsqu'il s'exécute en tant qu'utilisateur autre que root, FrankenPHP a besoin de la capacité `CAP_NET_BIND_SERVICE`
+pour que son serveur utilise les ports privilégiés (80 et 443).
+
+Si vous exposez FrankenPHP sur un port non privilégié (à partir de 1024), il est possible de faire fonctionner le serveur web avec un utilisateur qui n'est pas root, et sans avoir besoin d'aucune capacité.
+
+```dockerfile
+FROM dunglas/frankenphp
+
+ARG USER=appuser
+
+RUN \
+	# Utiliser "adduser -D ${USER}" pour les distros basées sur Alpine
+	useradd ${USER}; \
+	# Supprimer la capacité par défaut \
+	setcap -r /usr/local/bin/frankenphp; \
+	# Donner un accès en écriture à /data/caddy et /config/caddy \
+	chown -R ${USER}:${USER} /data/caddy && chown -R ${USER}:${USER} /config/caddy
+
+USER ${USER}
+```
+
+Ensuite, définissez la variable d'environnement `SERVER_NAME` pour utiliser un port non privilégié.
+Exemple `:8000`
+
+## Mises à jour
+
+Les images Docker sont construites :
+
+- lorsqu'une nouvelle version est taguée
+- tous les jours à 4h UTC, si de nouvelles versions des images officielles PHP sont disponibles
+
+## Versions de développement
+
+Les versions de développement sont disponibles dans le dépôt Docker [`dunglas/frankenphp-dev`](https://hub.docker.com/repository/docker/dunglas/frankenphp-dev). Un nouveau build est déclenché chaque fois qu'un commit est poussé sur la branche principale du dépôt GitHub.
+
+Les tags `latest*` pointent vers la tête de la branche `main`.
+Les tags sous la forme `sha-<hash-du-commit-git>` sont également disponibles.

+# Applications PHP en tant que binaires autonomes
+
+FrankenPHP a la capacité d'incorporer le code source et les assets des applications PHP dans un binaire statique et autonome.
+
+Grâce à cette fonctionnalité, les applications PHP peuvent être distribuées en tant que binaires autonomes qui incluent l'application elle-même, l'interpréteur PHP et Caddy, un serveur web de qualité production.
+
+Pour en savoir plus sur cette fonctionnalité, consultez [la présentation faite par Kévin à la SymfonyCon 2023](https://dunglas.dev/2023/12/php-and-symfony-apps-as-standalone-binaries/).
+
+Pour embarquer des applications Laravel, [lisez ce point spécifique de la documentation](laravel.md#les-applications-laravel-en-tant-que-binaires-autonomes).
+
+## Préparer votre application
+
+Avant de créer le binaire autonome, assurez-vous que votre application est prête à être intégrée.
+
+Vous devrez probablement :
+
+- Installer les dépendances de production de l'application
+- Dumper l'autoloader
+- Activer le mode production de votre application (si disponible)
+- Supprimer les fichiers inutiles tels que `.git` ou les tests pour réduire la taille de votre binaire final
+
+Par exemple, pour une application Symfony, lancez les commandes suivantes :
+
+```console
+# Exporter le projet pour se débarrasser de .git/, etc.
+mkdir $TMPDIR/my-prepared-app
+git archive HEAD | tar -x -C $TMPDIR/my-prepared-app
+cd $TMPDIR/my-prepared-app
+
+# Définir les variables d'environnement appropriées
+echo APP_ENV=prod > .env.local
+echo APP_DEBUG=0 >> .env.local
+
+# Supprimer les tests et autres fichiers inutiles pour économiser de l'espace
+# Alternativement, ajoutez ces fichiers avec l'attribut export-ignore dans votre fichier .gitattributes
+rm -Rf tests/
+
+# Installer les dépendances
+composer install --ignore-platform-reqs --no-dev -a
+
+# Optimiser le .env
+composer dump-env prod
+```
+
+### Personnaliser la configuration
+
+Pour personnaliser [la configuration](config.md),
+vous pouvez mettre un fichier `Caddyfile` ainsi qu'un fichier `php.ini`
+dans le répertoire principal de l'application à intégrer
+(`$TMPDIR/my-prepared-app` dans l'exemple précédent).
+
+## Créer un binaire Linux
+
+La manière la plus simple de créer un binaire Linux est d'utiliser le builder basé sur Docker que nous fournissons.
+
+1. Créez un fichier nommé `static-build.Dockerfile` dans le répertoire de votre application préparée :
+
+   ```dockerfile
+   FROM --platform=linux/amd64 dunglas/frankenphp:static-builder-gnu
+   # Si vous envisagez d'exécuter le binaire sur des systèmes musl-libc, utilisez plutôt static-builder-musl
+
+   # Copy your app
+   WORKDIR /go/src/app/dist/app
+   COPY . .
+
+   WORKDIR /go/src/app/
+   RUN EMBED=dist/app/ ./build-static.sh
+   ```
+
+   > [!CAUTION]
+   >
+   > Certains fichiers `.dockerignore` (par exemple celui fourni par défaut par [Symfony Docker](https://github.com/dunglas/symfony-docker/blob/main/.dockerignore))
+   > empêchent la copie du dossier `vendor/` et des fichiers `.env`. Assurez-vous d'ajuster ou de supprimer le fichier `.dockerignore` avant le build.
+
+2. Construisez:
+
+   ```console
+   docker build -t static-app -f static-build.Dockerfile .
+   ```
+
+3. Extrayez le binaire :
+
+   ```console
+   docker cp $(docker create --name static-app-tmp static-app):/go/src/app/dist/frankenphp-linux-x86_64 my-app ; docker rm static-app-tmp
+   ```
+
+Le binaire généré sera nommé `my-app` dans le répertoire courant.
+
+## Créer un binaire pour d'autres systèmes d'exploitation
+
+Si vous ne souhaitez pas utiliser Docker, ou souhaitez construire un binaire macOS, utilisez le script shell que nous fournissons :
+
+```console
+git clone https://github.com/php/frankenphp
+cd frankenphp
+EMBED=/path/to/your/app ./build-static.sh
+```
+
+Le binaire obtenu est le fichier nommé `frankenphp-<os>-<arch>` dans le répertoire `dist/`.
+
+## Utiliser le binaire
+
+C'est tout ! Le fichier `my-app` (ou `dist/frankenphp-<os>-<arch>` sur d'autres systèmes d'exploitation) contient votre application autonome !
+
+Pour démarrer l'application web, exécutez :
+
+```console
+./my-app php-server
+```
+
+Si votre application contient un [script worker](worker.md), démarrez le worker avec quelque chose comme :
+
+```console
+./my-app php-server --worker public/index.php
+```
+
+Pour activer HTTPS (un certificat Let's Encrypt est automatiquement créé), HTTP/2 et HTTP/3, spécifiez le nom de domaine à utiliser :
+
+```console
+./my-app php-server --domain localhost
+```
+
+Vous pouvez également exécuter les scripts CLI PHP incorporés dans votre binaire :
+
+```console
+./my-app php-cli bin/console
+```
+
+## Extensions PHP
+
+Par défaut, le script construira les extensions requises par le fichier `composer.json` de votre projet, s'il y en a.
+Si le fichier `composer.json` n'existe pas, les extensions par défaut sont construites, comme documenté dans [Créer un binaire statique](static.md).
+
+Pour personnaliser les extensions, utilisez la variable d'environnement `PHP_EXTENSIONS`.
+
+```console
+EMBED=/path/to/your/app \
+PHP_EXTENSIONS=ctype,iconv,pdo_sqlite \
+./build-static.sh
+```
+
+## Personnaliser la compilation
+
+[Consultez la documentation sur la compilation statique](static.md) pour voir comment personnaliser le binaire (extensions, version PHP...).
+
+## Distribuer le binaire
+
+Sous Linux, le binaire est compressé par défaut à l'aide de [UPX](https://upx.github.io).
+
+Sous Mac, pour réduire la taille du fichier avant de l'envoyer, vous pouvez le compresser.
+Nous recommandons `xz`.

+# Écrire des extensions PHP en Go
+
+Avec FrankenPHP, vous pouvez **écrire des extensions PHP en Go**, ce qui vous permet de créer des **fonctions natives haute performance** qui peuvent être appelées directement depuis PHP. Vos applications peuvent tirer parti de toute bibliothèque Go existante ou nouvelle, ainsi que du célèbre modèle de concurrence des **goroutines directement depuis votre code PHP**.
+
+L'écriture d'extensions PHP se fait généralement en C, mais il est également possible de les écrire dans d'autres langages avec un peu de travail supplémentaire. Les extensions PHP permettent de tirer parti de la puissance des langages de bas niveau pour étendre les fonctionnalités de PHP, par exemple, en ajoutant des fonctions natives ou en optimisant des opérations spécifiques.
+
+Grâce aux modules Caddy, vous pouvez écrire des extensions PHP en Go et les intégrer très rapidement dans FrankenPHP.
+
+## Deux Approches
+
+FrankenPHP offre deux façons de créer des extensions PHP en Go :
+
+1. **Utilisation du Générateur d'Extensions** - L'approche recommandée qui génère tout le code standard nécessaire pour la plupart des cas d'usage, vous permettant de vous concentrer sur l'écriture de votre code Go
+2. **Implémentation Manuelle** - Contrôle total sur la structure de l'extension pour les cas d'usage avancés
+
+Nous commencerons par l'approche du générateur, car c'est le moyen le plus facile de commencer, puis nous montrerons l'implémentation manuelle pour ceux qui ont besoin d'un contrôle complet.
+
+## Utilisation du Générateur d'Extensions
+
+FrankenPHP est livré avec un outil qui vous permet de **créer une extension PHP** en utilisant uniquement Go. **Pas besoin d'écrire du code C** ou d'utiliser CGO directement : FrankenPHP inclut également une **API de types publique** pour vous aider à écrire vos extensions en Go sans avoir à vous soucier du **jonglage de types entre PHP/C et Go**.
+
+> [!TIP]
+> Si vous voulez comprendre comment les extensions peuvent être écrites en Go à partir de zéro, vous pouvez lire la section d'implémentation manuelle ci-dessous démontrant comment écrire une extension PHP en Go sans utiliser le générateur.
+
+Gardez à l'esprit que cet outil n'est **pas un générateur d'extensions complet**. Il est destiné à vous aider à écrire des extensions simples en Go, mais il ne fournit pas les fonctionnalités les plus avancées des extensions PHP. Si vous devez écrire une extension plus **complexe et optimisée**, vous devrez peut-être écrire du code C ou utiliser CGO directement.
+
+### Prérequis
+
+Comme aussi couvert dans la section d'implémentation manuelle ci-dessous, vous devez [obtenir les sources PHP](https://www.php.net/downloads.php) et créer un nouveau module Go.
+
+#### Créer un Nouveau Module et Obtenir les Sources PHP
+
+La première étape pour écrire une extension PHP en Go est de créer un nouveau module Go. Vous pouvez utiliser la commande suivante pour cela :
+
+```console
+go mod init github.com/my-account/my-module
+```
+
+La seconde étape est [l'obtention des sources PHP](https://www.php.net/downloads.php) pour les étapes suivantes. Une fois que vous les avez, décompressez-les dans le répertoire de votre choix, mais pas à l'intérieur de votre module Go :
+
+```console
+tar xf php-*
+```
+
+### Écrire l'Extension
+
+Tout est maintenant configuré pour écrire votre fonction native en Go. Créez un nouveau fichier nommé `stringext.go`. Notre première fonction prendra une chaîne comme argument, le nombre de fois à la répéter, un booléen pour indiquer s'il faut inverser la chaîne, et retournera la chaîne résultante. Cela devrait ressembler à ceci :
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "strings"
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:function repeat_this(string $str, int $count, bool $reverse): string
+func repeat_this(s *C.zend_string, count int64, reverse bool) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    result := strings.Repeat(str, int(count))
+    if reverse {
+        runes := []rune(result)
+        for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
+            runes[i], runes[j] = runes[j], runes[i]
+        }
+        result = string(runes)
+    }
+
+    return frankenphp.PHPString(result, false)
+}
+```
+
+Il y a deux choses importantes à noter ici :
+
+- Une directive `//export_php:function` définit la signature de la fonction en PHP. C'est ainsi que le générateur sait comment générer la fonction PHP avec les bons paramètres et le bon type de retour ;
+- La fonction doit retourner un `unsafe.Pointer`. FrankenPHP fournit une API pour vous aider avec le jonglage de types entre C et Go.
+
+Alors que le premier point parle de lui-même, le second peut être plus difficile à appréhender. Plongeons plus profondément dans le jonglage de types dans la section suivante.
+
+### Jonglage de Types
+
+Bien que certains types de variables aient la même représentation mémoire entre C/PHP et Go, certains types nécessitent plus de logique pour être directement utilisés. C'est peut-être la partie la plus difficile quand il s'agit d'écrire des extensions car cela nécessite de comprendre les fonctionnements internes du moteur Zend et comment les variables sont stockées dans le moteur de PHP. Ce tableau résume ce que vous devez savoir :
+
+| Type PHP           | Type Go                       | Conversion directe | Assistant C vers Go               | Assistant Go vers C                | Support des Méthodes de Classe |

+
+> [!NOTE]
+> Ce tableau n'est pas encore exhaustif et sera complété au fur et à mesure que l'API de types FrankenPHP deviendra plus complète.
+>
+> Pour les méthodes de classe spécifiquement, les types primitifs et les tableaux sont supportés. Les objets ne peuvent pas encore être utilisés comme paramètres de méthode ou types de retour.
+
+Si vous vous référez à l'extrait de code de la section précédente, vous pouvez voir que des assistants sont utilisés pour convertir le premier paramètre et la valeur de retour. Les deuxième et troisième paramètres de notre fonction `repeat_this()` n'ont pas besoin d'être convertis car la représentation mémoire des types sous-jacents est la même pour C et Go.
+
+#### Travailler avec les Tableaux
+
+FrankenPHP fournit un support natif pour les tableaux PHP à travers `frankenphp.AssociativeArray` ou une conversion directe vers une map ou un slice.
+
+`AssociativeArray` représente une [hash map](https://fr.wikipedia.org/wiki/Table_de_hachage) composée d'un champ `Map: map[string]any` et d'un champ optionnel `Order: []string` (contrairement aux "tableaux associatifs" PHP, les maps Go ne sont pas ordonnées).
+
+Si l'ordre ou l'association ne sont pas nécessaires, il est également possible de convertir directement vers un slice `[]any` ou une map non ordonnée `map[string]any`.
+
+**Créer et manipuler des tableaux en Go :**
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+// export_php:function process_data_ordered(array $input): array
+func process_data_ordered_map(arr *C.zval) unsafe.Pointer {
+    // Convertir le tableau associatif PHP vers Go en conservant l'ordre
+    associativeArray, err := frankenphp.GoAssociativeArray[any](unsafe.Pointer(arr))
+    if err != nil {
+        // gérer l'erreur
+    }
+
+    // parcourir les entrées dans l'ordre
+    for _, key := range associativeArray.Order {
+        value, _ = associativeArray.Map[key]
+        // faire quelque chose avec key et value
+    }
+
+    // retourner un tableau ordonné
+    // si 'Order' n'est pas vide, seules les paires clé-valeur dans 'Order' seront respectées
+    return frankenphp.PHPAssociativeArray[string](frankenphp.AssociativeArray[string]{
+        Map: map[string]string{
+            "key1": "value1",
+            "key2": "value2",
+        },
+        Order: []string{"key1", "key2"},
+    })
+}
+
+// export_php:function process_data_unordered(array $input): array
+func process_data_unordered_map(arr *C.zval) unsafe.Pointer {
+    // Convertir le tableau associatif PHP vers une map Go sans conserver l'ordre
+    // ignorer l'ordre sera plus performant
+    goMap, err := frankenphp.GoMap[any](unsafe.Pointer(arr))
+    if err != nil {
+        // gérer l'erreur
+    }
+
+    // parcourir les entrées sans ordre spécifique
+    for key, value := range goMap {
+        // faire quelque chose avec key et value
+    }
+
+    // retourner un tableau non ordonné
+    return frankenphp.PHPMap(map[string]string {
+        "key1": "value1",
+        "key2": "value2",
+    })
+}
+
+// export_php:function process_data_packed(array $input): array
+func process_data_packed(arr *C.zval) unsafe.Pointer {
+    // Convertir le tableau packed PHP vers Go
+    goSlice, err := frankenphp.GoPackedArray(unsafe.Pointer(arr))
+    if err != nil {
+        // gérer l'erreur
+    }
+
+    // parcourir le slice dans l'ordre
+    for index, value := range goSlice {
+        // faire quelque chose avec index et value
+    }
+
+    // retourner un tableau packed
+    return frankenphp.PHPPackedArray([]string{"value1", "value2", "value3"})
+}
+```
+
+**Fonctionnalités clés de la conversion de tableaux :**
+
+- **Paires clé-valeur ordonnées** - Option pour conserver l'ordre du tableau associatif
+- **Optimisé pour plusieurs cas** - Option de ne pas conserver l'ordre pour de meilleures performances ou conversion directe vers un slice
+- **Détection automatique de liste** - Lors de la conversion vers PHP, détecte automatiquement si le tableau doit être une liste packed ou un hashmap
+- **Tableaux imbriqués** - Les tableaux peuvent être imbriqués et convertiront automatiquement tous les types supportés (`int64`, `float64`, `string`, `bool`, `nil`, `AssociativeArray`, `map[string]any`, `[]any`)
+- **Les objets ne sont pas supportés** - Actuellement, seuls les types scalaires et les tableaux peuvent être utilisés comme valeurs. Fournir un objet résultera en une valeur `null` dans le tableau PHP.
+
+##### Méthodes disponibles : Packed et Associatif
+
+- `frankenphp.PHPAssociativeArray(arr frankenphp.AssociativeArray) unsafe.Pointer` - Convertir vers un tableau PHP ordonné avec des paires clé-valeur
+- `frankenphp.PHPMap(arr map[string]any) unsafe.Pointer` - Convertir une map vers un tableau PHP non ordonné avec des paires clé-valeur
+- `frankenphp.PHPPackedArray(slice []any) unsafe.Pointer` - Convertir un slice vers un tableau PHP packed avec uniquement des valeurs indexées
+- `frankenphp.GoAssociativeArray(arr unsafe.Pointer, ordered bool) frankenphp.AssociativeArray` - Convertir un tableau PHP vers un `AssociativeArray` Go ordonné (map avec ordre)
+- `frankenphp.GoMap(arr unsafe.Pointer) map[string]any` - Convertir un tableau PHP vers une map Go non ordonnée
+- `frankenphp.GoPackedArray(arr unsafe.Pointer) []any` - Convertir un tableau PHP vers un slice Go
+- `frankenphp.IsPacked(zval *C.zend_array) bool` - Vérifie si le tableau PHP est une liste ou un tableau associatif
+
+### Travailler avec des Callables
+
+FrankenPHP propose un moyen de travailler avec les _callables_ PHP grâce au helper `frankenphp.CallPHPCallable()`. Cela permet d'appeler des fonctions ou des méthodes PHP depuis du code Go.
+
+Pour illustrer cela, créons notre propre fonction `array_map()` qui prend un _callable_ et un tableau, applique le _callable_ à chaque élément du tableau, et retourne un nouveau tableau avec les résultats :
+
+```go
+// export_php:function my_array_map(array $data, callable $callback): array
+func my_array_map(arr *C.zend_array, callback *C.zval) unsafe.Pointer {
+	goSlice, err := frankenphp.GoPackedArray[any](unsafe.Pointer(arr))
+	if err != nil {
+		panic(err)
+	}
+
+	result := make([]any, len(goSlice))
+
+	for index, value := range goSlice {
+		result[index] = frankenphp.CallPHPCallable(unsafe.Pointer(callback), []interface{}{value})
+	}
+
+	return frankenphp.PHPPackedArray(result)
+}
+```
+
+Remarquez comment nous utilisons `frankenphp.CallPHPCallable()` pour appeler le _callable_ PHP passé en paramètre. Cette fonction prend un pointeur vers le _callable_ et un tableau d'arguments, et elle retourne le résultat de l'exécution du _callable_. Vous pouvez utiliser la syntaxe habituelle des _callables_ :
+
+```php
+<?php
+
+$result = my_array_map([1, 2, 3], function($x) { return $x * 2; });
+// $result vaudra [2, 4, 6]
+
+$result = my_array_map(['hello', 'world'], 'strtoupper');
+// $result vaudra ['HELLO', 'WORLD']
+```
+
+### Déclarer une Classe PHP Native
+
+Le générateur prend en charge la déclaration de **classes opaques** comme structures Go, qui peuvent être utilisées pour créer des objets PHP. Vous pouvez utiliser la directive `//export_php:class` pour définir une classe PHP. Par exemple :
+
+```go
+package example
+
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+```
+
+#### Que sont les Classes Opaques ?
+
+Les **classes opaques** sont des classes avec lesquelles la structure interne (comprendre : les propriétés) est cachée du code PHP. Cela signifie :
+
+- **Pas d'accès direct aux propriétés** : Vous ne pouvez pas lire ou écrire des propriétés directement depuis PHP (`$user->name` ne fonctionnera pas)
+- **Interface uniquement par méthodes** - Toutes les interactions doivent passer par les méthodes que vous définissez
+- **Meilleure encapsulation** - La structure de données interne est complètement contrôlée par le code Go
+- **Sécurité de type** - Aucun risque que le code PHP corrompe l'état interne avec de mauvais types
+- **API plus propre** - Force à concevoir une interface publique appropriée
+
+Cette approche fournit une meilleure encapsulation et empêche le code PHP de corrompre accidentellement l'état interne de vos objets Go. Toutes les interactions avec l'objet doivent passer par les méthodes que vous définissez explicitement.
+
+#### Ajouter des Méthodes aux Classes
+
+Puisque les propriétés ne sont pas directement accessibles, vous **devez définir des méthodes** pour interagir avec vos classes opaques. Utilisez la directive `//export_php:method` pour définir cela :
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:class User
+type UserStruct struct {
+    Name string
+    Age  int
+}
+
+//export_php:method User::getName(): string
+func (us *UserStruct) GetUserName() unsafe.Pointer {
+    return frankenphp.PHPString(us.Name, false)
+}
+
+//export_php:method User::setAge(int $age): void
+func (us *UserStruct) SetUserAge(age int64) {
+    us.Age = int(age)
+}
+
+//export_php:method User::getAge(): int
+func (us *UserStruct) GetUserAge() int64 {
+    return int64(us.Age)
+}
+
+//export_php:method User::setNamePrefix(string $prefix = "User"): void
+func (us *UserStruct) SetNamePrefix(prefix *C.zend_string) {
+    us.Name = frankenphp.GoString(unsafe.Pointer(prefix)) + ": " + us.Name
+}
+```
+
+#### Paramètres Nullables
+
+Le générateur prend en charge les paramètres nullables en utilisant le préfixe `?` dans les signatures PHP. Quand un paramètre est nullable, il devient un pointeur dans votre fonction Go, vous permettant de vérifier si la valeur était `null` en PHP :
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:method User::updateInfo(?string $name, ?int $age, ?bool $active): void
+func (us *UserStruct) UpdateInfo(name *C.zend_string, age *int64, active *bool) {
+    // Vérifier si name a été fourni (pas null)
+    if name != nil {
+        us.Name = frankenphp.GoString(unsafe.Pointer(name))
+    }
+
+    // Vérifier si age a été fourni (pas null)
+    if age != nil {
+        us.Age = int(*age)
+    }
+
+    // Vérifier si active a été fourni (pas null)
+    if active != nil {
+        us.Active = *active
+    }
+}
+```
+
+**Points clés sur les paramètres nullables :**
+
+- **Types primitifs nullables** (`?int`, `?float`, `?bool`) deviennent des pointeurs (`*int64`, `*float64`, `*bool`) en Go
+- **Chaînes nullables** (`?string`) restent comme `*C.zend_string` mais peuvent être `nil`
+- **Vérifiez `nil`** avant de déréférencer les valeurs de pointeur
+- **PHP `null` devient Go `nil`** - quand PHP passe `null`, votre fonction Go reçoit un pointeur `nil`
+
+> [!WARNING]
+> Actuellement, les méthodes de classe ont les limitations suivantes. **Les objets ne sont pas supportés** comme types de paramètres ou types de retour. **Les tableaux sont entièrement supportés** pour les paramètres et types de retour. Types supportés : `string`, `int`, `float`, `bool`, `array`, et `void` (pour le type de retour). **Les types de paramètres nullables sont entièrement supportés** pour tous les types scalaires (`?string`, `?int`, `?float`, `?bool`).
+
+Après avoir généré l'extension, vous serez autorisé à utiliser la classe et ses méthodes en PHP. Notez que vous **ne pouvez pas accéder aux propriétés directement** :
+
+```php
+<?php
+
+$user = new User();
+
+// ✅ Fonctionne - utilisation des méthodes
+$user->setAge(25);
+echo $user->getName();           // Output : (vide, valeur par défaut)
+echo $user->getAge();            // Output : 25
+$user->setNamePrefix("Employee");
+
+// ✅ Fonctionne aussi - paramètres nullables
+$user->updateInfo("John", 30, true);        // Tous les paramètres fournis
+$user->updateInfo("Jane", null, false);     // L'âge est null
+$user->updateInfo(null, 25, null);          // Le nom et actif sont null
+
+// ❌ Ne fonctionnera PAS - accès direct aux propriétés
+// echo $user->name;             // Erreur : Impossible d'accéder à la propriété privée
+// $user->age = 30;              // Erreur : Impossible d'accéder à la propriété privée
+```
+
+Cette conception garantit que votre code Go a un contrôle complet sur la façon dont l'état de l'objet est accédé et modifié, fournissant une meilleure encapsulation et sécurité de type.
+
+### Déclarer des Constantes
+
+Le générateur prend en charge l'exportation de constantes Go vers PHP en utilisant deux directives : `//export_php:const` pour les constantes globales et `//export_php:classconst` pour les constantes de classe. Cela vous permet de partager des valeurs de configuration, des codes de statut et d'autres constantes entre le code Go et PHP.
+
+#### Constantes Globales
+
+Utilisez la directive `//export_php:const` pour créer des constantes PHP globales :
+
+```go
+package example
+
+//export_php:const
+const MAX_CONNECTIONS = 100
+
+//export_php:const
+const API_VERSION = "1.2.3"
+
+//export_php:const
+const STATUS_OK = iota
+
+//export_php:const
+const STATUS_ERROR = iota
+```
+
+#### Constantes de Classe
+
+Utilisez la directive `//export_php:classconst ClassName` pour créer des constantes qui appartiennent à une classe PHP spécifique :
+
+```go
+package example
+
+//export_php:classconst User
+const STATUS_ACTIVE = 1
+
+//export_php:classconst User
+const STATUS_INACTIVE = 0
+
+//export_php:classconst User
+const ROLE_ADMIN = "admin"
+
+//export_php:classconst Order
+const STATE_PENDING = iota
+
+//export_php:classconst Order
+const STATE_PROCESSING = iota
+
+//export_php:classconst Order
+const STATE_COMPLETED = iota
+```
+
+Les constantes de classe sont accessibles en utilisant la portée du nom de classe en PHP :
+
+```php
+<?php
+
+// Constantes globales
+echo MAX_CONNECTIONS;    // 100
+echo API_VERSION;        // "1.2.3"
+
+// Constantes de classe
+echo User::STATUS_ACTIVE;    // 1
+echo User::ROLE_ADMIN;       // "admin"
+echo Order::STATE_PENDING;   // 0
+```
+
+La directive prend en charge divers types de valeurs incluant les chaînes, entiers, booléens, flottants et constantes iota. Lors de l'utilisation de `iota`, le générateur assigne automatiquement des valeurs séquentielles (0, 1, 2, etc.). Les constantes globales deviennent disponibles dans votre code PHP comme constantes globales, tandis que les constantes de classe sont déclarées dans leurs classes respectives avec la visibilité publique. Lors de l'utilisation d'entiers, différentes notations possibles (binaire, hex, octale) sont supportées et dumpées telles quelles dans le fichier stub PHP.
+
+Vous pouvez utiliser les constantes comme vous êtes habitué dans le code Go. Par exemple, prenons la fonction `repeat_this()` que nous avons déclarée plus tôt et changeons le dernier argument en entier :
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "strings"
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:const
+const STR_REVERSE = iota
+
+//export_php:const
+const STR_NORMAL = iota
+
+//export_php:classconst StringProcessor
+const MODE_LOWERCASE = 1
+
+//export_php:classconst StringProcessor
+const MODE_UPPERCASE = 2
+
+//export_php:function repeat_this(string $str, int $count, int $mode): string
+func repeat_this(s *C.zend_string, count int64, mode int) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    result := strings.Repeat(str, int(count))
+    if mode == STR_REVERSE {
+        // inverser la chaîne
+    }
+
+    if mode == STR_NORMAL {
+        // no-op, juste pour montrer la constante
+    }
+
+    return frankenphp.PHPString(result, false)
+}
+
+//export_php:class StringProcessor
+type StringProcessorStruct struct {
+    // champs internes
+}
+
+//export_php:method StringProcessor::process(string $input, int $mode): string
+func (sp *StringProcessorStruct) Process(input *C.zend_string, mode int64) unsafe.Pointer {
+    str := frankenphp.GoString(unsafe.Pointer(input))
+
+    switch mode {
+    case MODE_LOWERCASE:
+        str = strings.ToLower(str)
+    case MODE_UPPERCASE:
+        str = strings.ToUpper(str)
+    }
+
+    return frankenphp.PHPString(str, false)
+}
+```
+
+### Utilisation des Espaces de Noms
+
+Le générateur prend en charge l'organisation des fonctions, classes et constantes de votre extension PHP sous un espace de noms (namespace) en utilisant la directive `//export_php:namespace`. Cela aide à éviter les conflits de noms et fournit une meilleure organisation pour l'API de votre extension.
+
+#### Déclarer un Espace de Noms
+
+Utilisez la directive `//export_php:namespace` en haut de votre fichier Go pour placer tous les symboles exportés sous un espace de noms spécifique :
+
+```go
+//export_php:namespace My\Extension
+package example
+
+import (
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export_php:function hello(): string
+func hello() string {
+    return "Bonjour depuis l'espace de noms My\\Extension !"
+}
+
+//export_php:class User
+type UserStruct struct {
+    // champs internes
+}
+
+//export_php:method User::getName(): string
+func (u *UserStruct) GetName() unsafe.Pointer {
+    return frankenphp.PHPString("Jean Dupont", false)
+}
+
+//export_php:const
+const STATUS_ACTIVE = 1
+```
+
+#### Utilisation de l'Extension avec Espace de Noms en PHP
+
+Quand un espace de noms est déclaré, toutes les fonctions, classes et constantes sont placées sous cet espace de noms en PHP :
+
+```php
+<?php
+
+echo My\Extension\hello(); // "Bonjour depuis l'espace de noms My\Extension !"
+
+$user = new My\Extension\User();
+echo $user->getName(); // "Jean Dupont"
+
+echo My\Extension\STATUS_ACTIVE; // 1
+```
+
+#### Notes Importantes
+
+- Seule **une** directive d'espace de noms est autorisée par fichier. Si plusieurs directives d'espace de noms sont trouvées, le générateur retournera une erreur.
+- L'espace de noms s'applique à **tous** les symboles exportés dans le fichier : fonctions, classes, méthodes et constantes.
+- Les noms d'espaces de noms suivent les conventions des espaces de noms PHP en utilisant les barres obliques inverses (`\`) comme séparateurs.
+- Si aucun espace de noms n'est déclaré, les symboles sont exportés vers l'espace de noms global comme d'habitude.
+
+### Générer l'Extension
+
+C'est là que la magie opère, et votre extension peut maintenant être générée. Vous pouvez exécuter le générateur avec la commande suivante :
+
+```console
+GEN_STUB_SCRIPT=php-src/build/gen_stub.php frankenphp extension-init my_extension.go
+```
+
+> [!NOTE]
+> N'oubliez pas de définir la variable d'environnement `GEN_STUB_SCRIPT` sur le chemin du fichier `gen_stub.php` dans les sources PHP que vous avez téléchargées plus tôt. C'est le même script `gen_stub.php` mentionné dans la section d'implémentation manuelle.
+
+Si tout s'est bien passé, un nouveau répertoire nommé `build` devrait avoir été créé. Ce répertoire contient les fichiers générés pour votre extension, incluant le fichier `my_extension.go` avec les stubs de fonction PHP générés.
+
+### Intégrer l'Extension Générée dans FrankenPHP
+
+Notre extension est maintenant prête à être compilée et intégrée dans FrankenPHP. Pour ce faire, référez-vous à la [documentation de compilation](compile.md) de FrankenPHP pour apprendre comment compiler FrankenPHP. Ajoutez le module en utilisant le flag `--with`, pointant vers le chemin de votre module :
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module/build
+```
+
+Notez que vous pointez vers le sous-répertoire `/build` qui a été créé pendant l'étape de génération. Cependant, ce n'est pas obligatoire : vous pouvez aussi copier les fichiers générés dans le répertoire de votre module et pointer directement vers lui.
+
+### Tester Votre Extension Générée
+
+Vous pouvez créer un fichier PHP pour tester les fonctions et classes que vous avez créées. Par exemple, créez un fichier `index.php` avec le contenu suivant :
+
+```php
+<?php
+
+// Utilisation des constantes globales
+var_dump(repeat_this('Hello World', 5, STR_REVERSE));
+
+// Utilisation des constantes de classe
+$processor = new StringProcessor();
+echo $processor->process('Hello World', StringProcessor::MODE_LOWERCASE);  // "hello world"
+echo $processor->process('Hello World', StringProcessor::MODE_UPPERCASE);  // "HELLO WORLD"
+```
+
+Une fois que vous avez intégré votre extension dans FrankenPHP comme indiqué dans la section précédente, vous pouvez exécuter ce fichier de test en utilisant `./frankenphp php-server`, et vous devriez voir votre extension fonctionner.
+
+## Implémentation Manuelle
+
+Si vous voulez comprendre comment les extensions fonctionnent ou avez besoin d'un contrôle total sur votre extension, vous pouvez les écrire manuellement. Cette approche vous donne un contrôle complet mais nécessite plus de code intermédiaire.
+
+### Fonction de Base
+
+Nous allons voir comment écrire une extension PHP simple en Go qui définit une nouvelle fonction native. Cette fonction sera appelée depuis PHP et déclenchera une goroutine qui enregistrera un message dans les logs de Caddy. Cette fonction ne prend aucun paramètre et ne retourne rien.
+
+#### Définir la Fonction Go
+
+Dans votre module, vous devez définir une nouvelle fonction native qui sera appelée depuis PHP. Pour ce faire, créez un fichier avec le nom que vous voulez, par exemple, `extension.go`, et ajoutez le code suivant :
+
+```go
+package example
+
+// #include "extension.h"
+import "C"
+import (
+    "log/slog"
+    "unsafe"
+
+    "github.com/dunglas/frankenphp"
+)
+
+func init() {
+    frankenphp.RegisterExtension(unsafe.Pointer(&C.ext_module_entry))
+}
+
+//export go_print_something
+func go_print_something() {
+    go func() {
+        slog.Info("Hello from a goroutine!")
+    }()
+}
+```
+
+La fonction `frankenphp.RegisterExtension()` simplifie le processus d'enregistrement d'extension en gérant la logique interne de PHP. La fonction `go_print_something` utilise la directive `//export` pour indiquer qu'elle sera accessible dans le code C que nous écrirons, grâce à CGO.
+
+Dans cet exemple, notre nouvelle fonction déclenchera une goroutine qui enregistrera un message dans les logs de Caddy.
+
+#### Définir la Fonction PHP
+
+Pour permettre à PHP d'appeler notre fonction, nous devons définir une fonction PHP correspondante. Pour cela, nous créerons un fichier stub, par exemple, `extension.stub.php`, qui contiendra le code suivant :
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+function go_print(): void {}
+```
+
+Ce fichier définit la signature de la fonction `go_print()`, qui sera appelée depuis PHP. La directive `@generate-class-entries` permet à PHP de générer automatiquement les entrées de fonction pour notre extension.
+
+Ceci n'est pas fait manuellement mais en utilisant un script fourni dans les sources PHP (assurez-vous d'ajuster le chemin vers le script `gen_stub.php` selon l'emplacement de vos sources PHP) :
+
+```bash
+php ../php-src/build/gen_stub.php extension.stub.php
+```
+
+Ce script générera un fichier nommé `extension_arginfo.h` qui contient les informations nécessaires pour que PHP sache comment définir et appeler notre fonction.
+
+#### Écrire le Pont entre Go et C
+
+Maintenant, nous devons écrire le pont entre Go et C. Créez un fichier nommé `extension.h` dans le répertoire de votre module avec le contenu suivant :
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+Ensuite, créez un fichier nommé `extension.c` qui effectuera les étapes suivantes :
+
+- Inclure les en-têtes PHP ;
+- Déclarer notre nouvelle fonction PHP native `go_print()` ;
+- Déclarer les métadonnées de l'extension.
+
+Commençons par inclure les en-têtes requis :
+
+```c
+#include <php.h>
+#include "extension.h"
+#include "extension_arginfo.h"
+
+// Contient les symboles exportés par Go
+#include "_cgo_export.h"
+```
+
+Nous définissons ensuite notre fonction PHP comme une fonction de langage natif :
+
+```c
+PHP_FUNCTION(go_print)
+{
+    ZEND_PARSE_PARAMETERS_NONE();
+
+    go_print_something();
+}
+
+zend_module_entry ext_module_entry = {
+    STANDARD_MODULE_HEADER,
+    "ext_go",
+    ext_functions, /* Functions */
+    NULL,          /* MINIT */
+    NULL,          /* MSHUTDOWN */
+    NULL,          /* RINIT */
+    NULL,          /* RSHUTDOWN */
+    NULL,          /* MINFO */
+    "0.1.1",
+    STANDARD_MODULE_PROPERTIES
+};
+```
+
+Dans ce cas, notre fonction ne prend aucun paramètre et ne retourne rien. Elle appelle simplement la fonction Go que nous avons définie plus tôt, exportée en utilisant la directive `//export`.
+
+Enfin, nous définissons les métadonnées de l'extension dans une structure `zend_module_entry`, telles que son nom, sa version et ses propriétés. Cette information est nécessaire pour que PHP reconnaisse et charge notre extension. Notez que `ext_functions` est un tableau de pointeurs vers les fonctions PHP que nous avons définies, et il a été automatiquement généré par le script `gen_stub.php` dans le fichier `extension_arginfo.h`.
+
+L'enregistrement de l'extension est automatiquement géré par la fonction `RegisterExtension()` de FrankenPHP que nous appelons dans notre code Go.
+
+### Usage Avancé
+
+Maintenant que nous savons comment créer une extension PHP de base en Go, complexifions notre exemple. Nous allons maintenant créer une fonction PHP qui prend une chaîne comme paramètre et retourne sa version en majuscules.
+
+#### Définir le Stub de Fonction PHP
+
+Pour définir la nouvelle fonction PHP, nous modifierons notre fichier `extension.stub.php` pour inclure la nouvelle signature de fonction :
+
+```php
+<?php
+
+/** @generate-class-entries */
+
+/**
+ * Convertit une chaîne en majuscules.
+ *
+ * @param string $string La chaîne à convertir.
+ * @return string La version en majuscules de la chaîne.
+ */
+function go_upper(string $string): string {}
+```
+
+> [!TIP]
+> Ne négligez pas la documentation de vos fonctions ! Vous êtes susceptible de partager vos stubs d'extension avec d'autres développeurs pour documenter comment utiliser votre extension et quelles fonctionnalités sont disponibles.
+
+En régénérant le fichier stub avec le script `gen_stub.php`, le fichier `extension_arginfo.h` devrait ressembler à ceci :
+
+```c
+ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(arginfo_go_upper, 0, 1, IS_STRING, 0)
+    ZEND_ARG_TYPE_INFO(0, string, IS_STRING, 0)
+ZEND_END_ARG_INFO()
+
+ZEND_FUNCTION(go_upper);
+
+static const zend_function_entry ext_functions[] = {
+    ZEND_FE(go_upper, arginfo_go_upper)
+    ZEND_FE_END
+};
+```
+
+Nous pouvons voir que la fonction `go_upper` est définie avec un paramètre de type `string` et un type de retour `string`.
+
+#### Jonglerie de Types entre Go et PHP/C
+
+Votre fonction Go ne peut pas accepter directement une chaîne PHP comme paramètre. Vous devez la convertir en chaîne Go. Heureusement, FrankenPHP fournit des fonctions d'aide pour gérer la conversion entre les chaînes PHP et les chaînes Go, similaire à ce que nous avons vu dans l'approche du générateur.
+
+Le fichier d'en-tête reste simple :
+
+```c
+#ifndef _EXTENSION_H
+#define _EXTENSION_H
+
+#include <php.h>
+
+extern zend_module_entry ext_module_entry;
+
+#endif
+```
+
+Nous pouvons maintenant écrire le pont entre Go et C dans notre fichier `extension.c`. Nous passerons la chaîne PHP directement à notre fonction Go :
+
+```c
+PHP_FUNCTION(go_upper)
+{
+    zend_string *str;
+
+    ZEND_PARSE_PARAMETERS_START(1, 1)
+        Z_PARAM_STR(str)
+    ZEND_PARSE_PARAMETERS_END();
+
+    zend_string *result = go_upper(str);
+    RETVAL_STR(result);
+}
+```
+
+Vous pouvez en apprendre plus sur `ZEND_PARSE_PARAMETERS_START` et l'analyse des paramètres dans la page dédiée du [PHP Internals Book](https://www.phpinternalsbook.com/php7/extensions_design/php_functions.html#parsing-parameters-zend-parse-parameters). Ici, nous disons à PHP que notre fonction prend un paramètre obligatoire de type `string` comme `zend_string`. Nous passons ensuite cette chaîne directement à notre fonction Go et retournons le résultat en utilisant `RETVAL_STR`.
+
+Il ne reste qu'une chose à faire : implémenter la fonction `go_upper` en Go.
+
+#### Implémenter la Fonction Go
+
+Notre fonction Go prendra un `*C.zend_string` comme paramètre, le convertira en chaîne Go en utilisant la fonction d'aide de FrankenPHP, le traitera, et retournera le résultat comme un nouveau `*C.zend_string`. Les fonctions d'aide gèrent toute la complexité de gestion de mémoire et de conversion pour nous.
+
+```go
+package example
+
+// #include <Zend/zend_types.h>
+import "C"
+import (
+    "unsafe"
+    "strings"
+
+    "github.com/dunglas/frankenphp"
+)
+
+//export go_upper
+func go_upper(s *C.zend_string) *C.zend_string {
+    str := frankenphp.GoString(unsafe.Pointer(s))
+
+    upper := strings.ToUpper(str)
+
+    return (*C.zend_string)(frankenphp.PHPString(upper, false))
+}
+```
+
+Cette approche est beaucoup plus propre et sûre que la gestion manuelle de la mémoire. Les fonctions d'aide de FrankenPHP gèrent la conversion entre le format `zend_string` de PHP et les chaînes Go automatiquement. Le paramètre `false` dans `PHPString()` indique que nous voulons créer une nouvelle chaîne non persistante (libérée à la fin de la requête).
+
+> [!TIP]
+> Dans cet exemple, nous n'effectuons aucune gestion d'erreur, mais vous devriez toujours vérifier que les pointeurs ne sont pas `nil` et que les données sont valides avant de les utiliser dans vos fonctions Go.
+
+### Intégrer l'Extension dans FrankenPHP
+
+Notre extension est maintenant prête à être compilée et intégrée dans FrankenPHP. Pour ce faire, référez-vous à la [documentation de compilation](compile.md) de FrankenPHP pour apprendre comment compiler FrankenPHP. Ajoutez le module en utilisant le flag `--with`, pointant vers le chemin de votre module :
+
+```console
+CGO_ENABLED=1 \
+XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
+CGO_CFLAGS=$(php-config --includes) \
+CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
+xcaddy build \
+    --output frankenphp \
+    --with github.com/my-account/my-module
+```
+
+C'est tout ! Votre extension est maintenant intégrée dans FrankenPHP et peut être utilisée dans votre code PHP.
+
+### Tester Votre Extension
+
+Après avoir intégré votre extension dans FrankenPHP, vous pouvez créer un fichier `index.php` avec des exemples pour les fonctions que vous avez implémentées :
+
+```php
+<?php
+
+// Tester la fonction de base
+go_print();
+
+// Tester la fonction avancée
+echo go_upper("hello world") . "\n";
+```
+
+Vous pouvez maintenant exécuter FrankenPHP avec ce fichier en utilisant `./frankenphp php-server`, et vous devriez voir votre extension fonctionner.

+
+Les extensions suivantes ont des bugs connus ou des comportements inattendus lorsqu'elles sont utilisées avec FrankenPHP :
+
+| Nom                                                           | Problème                                                                                                                                                                                                                                                                                                                                      |

+| [ext-openssl](https://www.php.net/manual/fr/book.openssl.php) | Lors de l'utilisation d'une version statique de FrankenPHP (construite avec la libc musl), l'extension OpenSSL peut planter sous de fortes charges. Une solution consiste à utiliser une version liée dynamiquement (comme celle utilisée dans les images Docker). Ce bogue est [suivi par PHP](https://github.com/php/php-src/issues/13648). |
+
+## get_browser
+
+La fonction [get_browser()](https://www.php.net/manual/fr/function.get-browser.php) semble avoir de mauvaises performances après un certain temps. Une solution est de mettre en cache (par exemple, avec [APCu](https://www.php.net/manual/en/book.apcu.php)) les résultats par agent utilisateur, car ils sont statiques.
+
+## Binaire autonome et images Docker basées sur Alpine
+
+Le binaire autonome et les images Docker basées sur Alpine (`dunglas/frankenphp:*-alpine`) utilisent [musl libc](https://musl.libc.org/) au lieu de [glibc et ses amis](https://www.etalabs.net/compare_libcs.html), pour garder une taille de binaire plus petite. Cela peut entraîner des problèmes de compatibilité. En particulier, le drapeau glob `GLOB_BRACE` n'est [pas disponible](https://www.php.net/manual/fr/function.glob.php).
+
+## Utilisation de `https://127.0.0.1` avec Docker
+
+Par défaut, FrankenPHP génère un certificat TLS pour `localhost`.
+C'est l'option la plus simple et recommandée pour le développement local.
+
+Si vous voulez vraiment utiliser `127.0.0.1` comme hôte, il est possible de configurer FrankenPHP pour générer un certificat pour cela en définissant le nom du serveur à `127.0.0.1`.
+
+Malheureusement, cela ne suffit pas lors de l'utilisation de Docker à cause de [son système de gestion des réseaux](https://docs.docker.com/network/).
+Vous obtiendrez une erreur TLS similaire à `curl: (35) LibreSSL/3.3.6: error:1404B438:SSL routines:ST_CONNECT:tlsv1 alert internal error`.
+
+Si vous utilisez Linux, une solution est d'utiliser [le pilote de réseau "hôte"](https://docs.docker.com/network/network-tutorial-host/) :
+
+```console
+docker run \
+    -e SERVER_NAME="127.0.0.1" \
+    -v $PWD:/app/public \
+    --network host \
+    dunglas/frankenphp
+```
+
+Le pilote de réseau "hôte" n'est pas pris en charge sur Mac et Windows. Sur ces plateformes, vous devrez deviner l'adresse IP du conteneur et l'inclure dans les noms de serveur.
+
+Exécutez la commande `docker network inspect bridge` et inpectez la clef `Containers` pour identifier la dernière adresse IP attribuée sous la clef `IPv4Address`, puis incrémentez-la d'un. Si aucun conteneur n'est en cours d'exécution, la première adresse IP attribuée est généralement `172.17.0.2`.
+
+Ensuite, incluez ceci dans la variable d'environnement `SERVER_NAME` :
+
+```console
+docker run \
+    -e SERVER_NAME="127.0.0.1, 172.17.0.3" \
+    -v $PWD:/app/public \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+> [!CAUTION]
+>
+> Assurez-vous de remplacer `172.17.0.3` par l'IP qui sera attribuée à votre conteneur.
+
+Vous devriez maintenant pouvoir accéder à `https://127.0.0.1` depuis la machine hôte.
+
+Si ce n'est pas le cas, lancez FrankenPHP en mode debug pour essayer de comprendre le problème :
+
+```console
+docker run \
+    -e CADDY_GLOBAL_OPTIONS="debug" \
+    -e SERVER_NAME="127.0.0.1" \
+    -v $PWD:/app/public \
+    -p 80:80 -p 443:443 -p 443:443/udp \
+    dunglas/frankenphp
+```
+
+## Scripts Composer Faisant Références à `@php`
+
+Les [scripts Composer](https://getcomposer.org/doc/articles/scripts.md) peuvent vouloir exécuter un binaire PHP pour certaines tâches, par exemple dans [un projet Laravel](laravel.md) pour exécuter `@php artisan package:discover --ansi`. Cela [echoue actuellement](https://github.com/php/frankenphp/issues/483#issuecomment-1899890915) pour deux raisons :
+
+- Composer ne sait pas comment appeler le binaire FrankenPHP ;
+- Composer peut ajouter des paramètres PHP en utilisant le paramètre `-d` dans la commande, ce que FrankenPHP ne supporte pas encore.
+
+Comme solution de contournement, nous pouvons créer un script shell dans `/usr/local/bin/php` qui supprime les paramètres non supportés et appelle ensuite FrankenPHP :
+
+```bash
+#!/usr/bin/env bash
+args=("$@")
+index=0
+for i in "$@"
+do
+    if [ "$i" == "-d" ]; then
+        unset 'args[$index]'
+        unset 'args[$index+1]'
+    fi
+    index=$((index+1))
+done
+
+/usr/local/bin/frankenphp php-cli ${args[@]}
+```
+
+Ensuite, mettez la variable d'environnement `PHP_BINARY` au chemin de notre script `php` et lancez Composer :
+
+```console
+export PHP_BINARY=/usr/local/bin/php
+composer install
+```
+
+## Résolution des problèmes TLS/SSL avec les binaires statiques
+
+Lorsque vous utilisez les binaires statiques, vous pouvez rencontrer les erreurs suivantes liées à TLS, par exemple lors de l'envoi de courriels utilisant STARTTLS :
+
+```text
+Unable to connect with STARTTLS: stream_socket_enable_crypto(): SSL operation failed with code 5. OpenSSL Error messages:
+error:80000002:system library::No such file or directory
+error:80000002:system library::No such file or directory
+error:80000002:system library::No such file or directory
+error:0A000086:SSL routines::certificate verify failed
+```
+
+Comme le binaire statique ne contient pas de certificats TLS, vous devez indiquer à OpenSSL l'installation de vos certificats CA locaux.
+
+Inspectez la sortie de [`openssl_get_cert_locations()`](https://www.php.net/manual/en/function.openssl-get-cert-locations.php),
+pour trouver l'endroit où les certificats CA doivent être installés et stockez-les à cet endroit.
+
+> [!WARNING]
+>
+> Les contextes Web et CLI peuvent avoir des paramètres différents.
+> Assurez-vous d'exécuter `openssl_get_cert_locations()` dans le bon contexte.
+
+[Les certificats CA extraits de Mozilla peuvent être téléchargés sur le site de cURL](https://curl.se/docs/caextract.html).
+
+Alternativement, de nombreuses distributions, y compris Debian, Ubuntu, et Alpine fournissent des paquets nommés `ca-certificates` qui contiennent ces certificats.
+
+Il est également possible d'utiliser `SSL_CERT_FILE` et `SSL_CERT_DIR` pour indiquer à OpenSSL où chercher les certificats CA :
+
+```console
+# Définir les variables d'environnement des certificats TLS
+export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
+export SSL_CERT_DIR=/etc/ssl/certs
+```

+# Laravel
+
+## Docker
+
+Déployer une application web [Laravel](https://laravel.com) avec FrankenPHP est très facile. Il suffit de monter le projet dans le répertoire `/app` de l'image Docker officielle.
+
+Exécutez cette commande depuis le répertoire principal de votre application Laravel :
+
+```console
+docker run -p 80:80 -p 443:443 -p 443:443/udp -v $PWD:/app dunglas/frankenphp
+```
+
+Et profitez !
+
+## Installation Locale
+
+Vous pouvez également exécuter vos projets Laravel avec FrankenPHP depuis votre machine locale :
+
+1. [Téléchargez le binaire correspondant à votre système](README.md#binaire-autonome)
+2. Ajoutez la configuration suivante dans un fichier nommé `Caddyfile` placé dans le répertoire racine de votre projet Laravel :
+
+   ```caddyfile
+   {
+   	frankenphp
+   }
+
+   # Le nom de domaine de votre serveur
+   localhost {
+   	# Définir le répertoire racine sur le dossier public/
+   	root public/
+   	# Autoriser la compression (optionnel)
+   	encode zstd br gzip
+   	# Exécuter les scripts PHP du dossier public/ et servir les assets
+   	php_server {
+   		try_files {path} index.php
+   	}
+   }
+   ```
+
+3. Démarrez FrankenPHP depuis le répertoire racine de votre projet Laravel : `frankenphp run`
+
+## Laravel Octane
+
+Octane peut être installé via le gestionnaire de paquets Composer :
+
+```console
+composer require laravel/octane
+```
+
+Après avoir installé Octane, vous pouvez exécuter la commande Artisan `octane:install`, qui installera le fichier de configuration d'Octane dans votre application :
+
+```console
+php artisan octane:install --server=frankenphp
+```
+
+Le serveur Octane peut être démarré via la commande Artisan `octane:frankenphp`.
+
+```console
+php artisan octane:frankenphp
+```
+
+La commande `octane:frankenphp` peut prendre les options suivantes :
+
+- `--host` : L'adresse IP à laquelle le serveur doit se lier (par défaut : `127.0.0.1`)
+- `--port` : Le port sur lequel le serveur doit être disponible (par défaut : `8000`)
+- `--admin-port` : Le port sur lequel le serveur administratif doit être disponible (par défaut : `2019`)
+- `--workers` : Le nombre de workers qui doivent être disponibles pour traiter les requêtes (par défaut : `auto`)
+- `--max-requests` : Le nombre de requêtes à traiter avant de recharger le serveur (par défaut : `500`)
+- `--caddyfile` : Le chemin vers le fichier `Caddyfile` de FrankenPHP
+- `--https` : Activer HTTPS, HTTP/2, et HTTP/3, et générer automatiquement et renouveler les certificats
+- `--http-redirect` : Activer la redirection HTTP vers HTTPS (uniquement activé si --https est passé)
+- `--watch` : Recharger automatiquement le serveur lorsque l'application est modifiée
+- `--poll` : Utiliser le sondage du système de fichiers pendant la surveillance pour surveiller les fichiers sur un réseau
+- `--log-level` : Enregistrer les messages au niveau de journalisation spécifié ou au-dessus, en utilisant le logger natif de Caddy
+
+> [!TIP]
+> Pour obtenir des logs structurés en JSON logs (utile quand vous utilisez des solutions d'analyse de logs), passez explicitement l'option `--log-level`.

+
+## Les Applications Laravel En Tant Que Binaires Autonomes
+
+En utilisant la [fonctionnalité d'intégration d'applications de FrankenPHP](embed.md), il est possible de distribuer
+les applications Laravel sous forme de binaires autonomes.
+
+Suivez ces étapes pour empaqueter votre application Laravel en tant que binaire autonome pour Linux :
+
+1. Créez un fichier nommé `static-build.Dockerfile` dans le dépôt de votre application :
+
+   ```dockerfile
+   FROM --platform=linux/amd64 dunglas/frankenphp:static-builder-gnu
+   # Si vous avez l'intention d'exécuter le binaire sur des systèmes musl-libc, utilisez plutôt static-builder-musl
+
+   # Copiez votre application
+   WORKDIR /go/src/app/dist/app
+   COPY . .
+
+   # Supprimez les tests et autres fichiers inutiles pour gagner de la place
+   # Alternativement, ajoutez ces fichiers à un fichier .dockerignore
+   RUN rm -Rf tests/
+
+   # Copiez le fichier .env
+   RUN cp .env.example .env
+   # Modifier APP_ENV et APP_DEBUG pour qu'ils soient prêts pour la production
+   RUN sed -i'' -e 's/^APP_ENV=.*/APP_ENV=production/' -e 's/^APP_DEBUG=.*/APP_DEBUG=false/' .env
+
+   # Apportez d'autres modifications à votre fichier .env si nécessaire
+
+   # Installez les dépendances
+   RUN composer install --ignore-platform-reqs --no-dev -a
+
+   # Construire le binaire statique
+   WORKDIR /go/src/app/
+   RUN EMBED=dist/app/ ./build-static.sh
+   ```
+
+   > [!CAUTION]
+   >
+   > Certains fichiers `.dockerignore` ignoreront le répertoire `vendor/`
+   > et les fichiers `.env`. Assurez-vous d'ajuster ou de supprimer le fichier `.dockerignore` avant la construction.
+
+2. Build:
+
+   ```console
+   docker build -t static-laravel-app -f static-build.Dockerfile .
+   ```
+
+3. Extraire le binaire
+
+   ```console
+   docker cp $(docker create --name static-laravel-app-tmp static-laravel-app):/go/src/app/dist/frankenphp-linux-x86_64 frankenphp ; docker rm static-laravel-app-tmp
+   ```
+
+4. Remplir les caches :
+
+   ```console
+   frankenphp php-cli artisan optimize
+   ```
+
+5. Exécutez les migrations de base de données (s'il y en a) :
+
+   ```console
+   frankenphp php-cli artisan migrate
+   ```
+
+6. Générer la clé secrète de l'application :
+
+   ```console
+   frankenphp php-cli artisan key:generate
+   ```
+
+7. Démarrez le serveur:
+
+   ```console
+   frankenphp php-server
+   ```
+
+Votre application est maintenant prête !
+
+Pour en savoir plus sur les options disponibles et sur la construction de binaires pour d'autres systèmes d'exploitation,
+consultez la documentation [Applications PHP en tant que binaires autonomes](embed.md).
+
+### Changer le chemin de stockage
+
+Par défaut, Laravel stocke les fichiers téléchargés, les caches, les logs, etc. dans le répertoire `storage/` de l'application.
+Ceci n'est pas adapté aux applications embarquées, car chaque nouvelle version sera extraite dans un répertoire temporaire différent.
+
+Définissez la variable d'environnement `LARAVEL_STORAGE_PATH` (par exemple, dans votre fichier `.env`) ou appelez la méthode `Illuminate\Foundation\Application::useStoragePath()` pour utiliser un répertoire en dehors du répertoire temporaire.
+
+### Exécuter Octane avec des binaires autonomes
+
+Il est même possible d'empaqueter les applications Laravel Octane en tant que binaires autonomes !
+
+Pour ce faire, [installez Octane correctement](#laravel-octane) et suivez les étapes décrites dans [la section précédente](#les-applications-laravel-en-tant-que-binaires-autonomes).
+
+Ensuite, pour démarrer FrankenPHP en mode worker via Octane, exécutez :
+
+```console
+PATH="$PWD:$PATH" frankenphp php-cli artisan octane:frankenphp
+```
+
+> [!CAUTION]
+>
+> Pour que la commande fonctionne, le binaire autonome **doit** être nommé `frankenphp`
+> car Octane a besoin d'un programme nommé `frankenphp` disponible dans le chemin

+FrankenPHP est livré avec un hub [Mercure](https://mercure.rocks) intégré.
+Mercure permet de pousser des événements en temps réel vers tous les appareils connectés : ils recevront un événement JavaScript instantanément.
+
+Aucune bibliothèque JS ou SDK requis !
+
+![Mercure](../mercure-hub.png)
+
+Pour activer le hub Mercure, mettez à jour le `Caddyfile` comme décrit [sur le site de Mercure](https://mercure.rocks/docs/hub/config).

+# Performance
+
+Par défaut, FrankenPHP essaie d'offrir un bon compromis entre performance et facilité d'utilisation.
+Cependant, il est possible d'améliorer considérablement les performances en utilisant une configuration appropriée.
+
+## Nombre de threads et de workers
+
+Par défaut, FrankenPHP démarre deux fois plus de threads et de workers (en mode worker) que le nombre de CPU disponibles.
+
+Les valeurs appropriées dépendent fortement de la manière dont votre application est écrite, de ce qu'elle fait et de votre matériel.
+Nous recommandons vivement de modifier ces valeurs.
+
+Pour trouver les bonnes valeurs, il est souhaitable d'effectuer des tests de charge simulant le trafic réel.
+[k6](https://k6.io) et [Gatling](https://gatling.io) sont de bons outils pour cela.
+
+Pour configurer le nombre de threads, utilisez l'option `num_threads` des directives `php_server` et `php`.
+Pour changer le nombre de travailleurs, utilisez l'option `num` de la section `worker` de la directive `frankenphp`.
+
+### `max_threads`
+
+Bien qu'il soit toujours préférable de savoir exactement à quoi ressemblera votre trafic, les applications réelles
+ont tendance à être plus imprévisibles. Le paramètre `max_threads` permet à FrankenPHP de créer automatiquement des threads supplémentaires au moment de l'exécution, jusqu'à la limite spécifiée.
+`max_threads` peut vous aider à déterminer le nombre de threads dont vous avez besoin pour gérer votre trafic et peut rendre le serveur plus résistant aux pics de latence.
+Si elle est fixée à `auto`, la limite sera estimée en fonction de la valeur de `memory_limit` dans votre `php.ini`. Si ce n'est pas possible,
+`auto` prendra par défaut 2x `num_threads`. Gardez à l'esprit que `auto` peut fortement sous-estimer le nombre de threads nécessaires.
+`max_threads` est similaire à [pm.max_children](https://www.php.net/manual/en/install.fpm.configuration.php#pm.max-children) de PHP FPM. La principale différence est que FrankenPHP utilise des threads au lieu de
+processus et les délègue automatiquement à différents scripts de travail et au `mode classique` selon les besoins.
+
+## Mode worker
+
+Activer [le mode worker](worker.md) améliore considérablement les performances,
+mais votre application doit être adaptée pour être compatible avec ce mode :
+vous devez créer un script worker et vous assurer que l'application n'a pas de fuite de mémoire.
+
+## Ne pas utiliser musl
+
+Les binaires statiques que nous fournissons, ainsi que la variante Alpine Linux des images Docker officielles, utilisent [la bibliothèque musl](https://musl.libc.org).
+
+PHP est connu pour être [significativement plus lent](https://gitlab.alpinelinux.org/alpine/aports/-/issues/14381) lorsqu'il utilise cette bibliothèque C alternative au lieu de la bibliothèque GNU traditionnelle,
+surtout lorsqu'il est compilé en mode ZTS (_thread-safe_), ce qui est nécessaire pour FrankenPHP.
+
+En outre, [certains bogues ne se produisent que lors de l'utilisation de musl](https://github.com/php/php-src/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen+label%3ABug+musl).
+
+Dans les environnements de production, nous recommandons fortement d'utiliser la glibc.
+
+Cela peut être réalisé en utilisant les images Docker Debian (par défaut) et [en compilant FrankenPHP à partir des sources](compile.md).
+
+Alternativement, nous fournissons des binaires statiques compilés avec [l'allocateur mimalloc](https://github.com/microsoft/mimalloc), ce qui rend FrankenPHP+musl plus rapide (mais toujours plus lent que FrankenPHP+glibc).
+
+## Configuration du runtime Go
+
+FrankenPHP est écrit en Go.
+
+En général, le runtime Go ne nécessite pas de configuration particulière, mais dans certaines circonstances,
+une configuration spécifique améliore les performances.
+
+Vous voudrez probablement mettre la variable d'environnement `GODEBUG` à `cgocheck=0` (la valeur par défaut dans les images Docker de FrankenPHP).
+
+Si vous exécutez FrankenPHP dans des conteneurs (Docker, Kubernetes, LXC...) et que vous limitez la mémoire disponible pour les conteneurs,
+mettez la variable d'environnement `GOMEMLIMIT` à la quantité de mémoire disponible.
+
+Pour plus de détails, [la page de documentation Go dédiée à ce sujet](https://pkg.go.dev/runtime#hdr-Environment_Variables) est à lire absolument pour tirer le meilleur parti du runtime.
+
+## `file_server`
+
+Par défaut, la directive `php_server` met automatiquement en place un serveur de fichiers
+pour servir les fichiers statiques (assets) stockés dans le répertoire racine.
+
+Cette fonctionnalité est pratique, mais a un coût.
+Pour la désactiver, utilisez la configuration suivante :
+
+```caddyfile
+php_server {
+    file_server off
+}
+```
+
+## `try_files`
+
+En plus des fichiers statiques et des fichiers PHP, `php_server` essaiera aussi de servir les fichiers d'index
+et d'index de répertoire de votre application (`/path/` -> `/path/index.php`). Si vous n'avez pas besoin des index de répertoires,
+vous pouvez les désactiver en définissant explicitement `try_files` comme ceci :
+
+```caddyfile
+php_server {
+    try_files {path} index.php
+    root /root/to/your/app #  l'ajout explicite de la racine ici permet une meilleure mise en cache
+}
+```
+
+Cela permet de réduire considérablement le nombre d'opérations inutiles sur les fichiers.
+
+Une approche alternative avec 0 opérations inutiles sur le système de fichiers serait d'utiliser la directive `php`
+et de diviser les fichiers de PHP par chemin. Cette approche fonctionne bien si votre application entière est servie par un seul fichier d'entrée.
+Un exemple de [configuration](config.md#configuration-du-caddyfile) qui sert des fichiers statiques derrière un dossier `/assets` pourrait ressembler à ceci :
+
+```caddyfile
+route {
+    @assets {
+        path /assets/*
+    }
+
+    # tout ce qui se trouve derrière /assets est géré par le serveur de fichiers
+    file_server @assets {
+        root /root/to/your/app
+    }
+
+    #  tout ce qui n'est pas dans /assets est géré par votre index ou votre fichier PHP worker
+    rewrite index.php
+    php {
+        root /root/to/your/app #  l'ajout explicite de la racine ici permet une meilleure mise en cache
+    }
+}
+```
+
+## _Placeholders_
+
+Vous pouvez utiliser des [_placeholders_](https://caddyserver.com/docs/conventions#placeholders) dans les directives `root` et `env`.
+Cependant, cela empêche la mise en cache de ces valeurs et a un coût important en termes de performances.
+
+Si possible, évitez les _placeholders_ dans ces directives.
+
+## `resolve_root_symlink`
+
+Par défaut, si le _document root_ est un lien symbolique, il est automatiquement résolu par FrankenPHP (c'est nécessaire pour le bon fonctionnement de PHP).
+Si la racine du document n'est pas un lien symbolique, vous pouvez désactiver cette fonctionnalité.
+
+```caddyfile
+php_server {
+    resolve_root_symlink false
+}
+```
+
+Cela améliorera les performances si la directive `root` contient des [_placeholders_](https://caddyserver.com/docs/conventions#placeholders).
+Le gain sera négligeable dans les autres cas.
+
+## Journaux
+
+La journalisation est évidemment très utile, mais, par définition, elle nécessite des opérations d'_I/O_ et des allocations de mémoire,
+ce qui réduit considérablement les performances.
+Assurez-vous de [définir le niveau de journalisation](https://caddyserver.com/docs/caddyfile/options#log) correctement,
+et de ne journaliser que ce qui est nécessaire.
+
+## Performances de PHP
+
+FrankenPHP utilise l'interpréteur PHP officiel.
+Toutes les optimisations de performances habituelles liées à PHP s'appliquent à FrankenPHP.
+
+En particulier :
+
+- vérifiez que [OPcache](https://www.php.net/manual/en/book.opcache.php) est installé, activé et correctement configuré
+- activez [les optimisations de l'autoloader de Composer](https://getcomposer.org/doc/articles/autoloader-optimization.md)
+- assurez-vous que le cache `realpath` est suffisamment grand pour les besoins de votre application
+- utilisez le [pré-chargement](https://www.php.net/manual/en/opcache.preloading.php)
+
+Pour plus de détails, lisez [l'entrée de la documentation dédiée de Symfony](https://symfony.com/doc/current/performance.html)
+(la plupart des conseils sont utiles même si vous n'utilisez pas Symfony).
