📝 AI Summary 本文介绍了一种基于 GatewayWorker 实现 PHP 热重载的方法，通过在 `onWorkerStart` 中设置定时器监控指定目录下的 PHP 文件修改时间，一旦检测到文件变更，便向主进程发送信号触发自动重载，适用于开发环境快速迭代。

⭐ AI Evaluation 文章思路清晰，代码完整且可直接运行，实现了 GatewayWorker 环境下的热重载功能，对开发者具有实用价值。图片展示了实际效果，增强了说明力。唯一不足是官方文档被吐槽‘不忍直视’，反映出文档质量有待提升。整体内容质量较高，逻辑严谨，值得推荐。

## 原理
onWorkerStart事件时添加一个计时器，绑定文件监控的代码函数即可。
## 代码
```php
<?php
namespace app\index\controller;
use app\index\service\BaseService;
use \GatewayWorker\Lib\Gateway;
use Workerman\Lib\Timer;
use RecursiveDirectoryIterator;
use RecursiveIteratorIterator;

class Push extends Base
{
	
	//首页
    public static function onConnect($client_id)
    {
        Gateway::sendToClient($client_id, json_encode(array(
            'type'      => 'init',
            'client_id' => $client_id
        )));

}

// GatewayWorker建议不做任何业务逻辑，onMessage留空即可
    public static function onMessage($client_id, $message)
    {
        // $data= json_decode($message,true);
        // $op = $data['op'];
        // $data = $data['data'];

Gateway::sendToClient($client_id, json_encode(array(
                'data222'      => $message,
                'client_id' => $client_id
            )));

}

public static function onWorkerStart($businessWorker)
    {
        $last_mtime = time();
        $_dir = "/app/app/index/controller";
        Timer::add(1, function () use (&$_dir,&$last_mtime) {
            $dir_iterator = new RecursiveDirectoryIterator($_dir);
            $iterator = new RecursiveIteratorIterator($dir_iterator);
            foreach ($iterator as $file)
            {
                // only check php files
                if(pathinfo($file, PATHINFO_EXTENSION) != 'php')
                {
                    continue;
                }
                // check mtime
                if($last_mtime < $file->getMTime())
                {
                    echo $file." update and reload\n";
                    // send SIGUSR1 signal to master process for reload
                    posix_kill(posix_getppid(), SIGUSR1);
                    $last_mtime = $file->getMTime();
                    break;
                }
            }
        });
    }
}

```
