workerman-filemonitor只能用于linux，但是我们平时开发都是用的windows。基于workerman-filemonitor二次修改，可完美实现windwos开发时的代码热更新。

经过测试，windows下不能直接在filemonitor启动的进程中获取我们需要的父进程，所以需要在你启动的gateway文件中添加如下代码（该代码一定要放在Worker::runAll()之前）

require_once __DIR__ . '/FileMonitor.php';

new FileMonitor($web, 'www', 5);

FileMonitor.php

<?php



use \Workerman\Worker;

use \Workerman\Lib\Timer;



/**

 * workerman-filemonitor for windows

 *

 * 监控文件更新并自动reload workerman

 *

 * 使用方法:

 * require_once __DIR__ . '/FileMonitor.php';

 * new FileMonitor($worker, $dir, $timer);

 */

class FileMonitor

{

    //待监听的项目目录

    private $_monitor_dir = '';



    //热更新间隔时间,默认3s

    private $_interval = 0;



    //最后一次同步时间

    private $_last_time = 0;



    function __construct ($worker, $dir, $timer = 3)

    {

        // watch Applications catalogue

        $this->_monitor_dir = __DIR__ .'/'. $dir;



        $this->_interval = $timer;



        $this->_last_time = time();



        // Emitted when data received

        $worker->reloadable = false;



        // Emitted when data received

        $worker->onWorkerStart = function()

        {

            // watch files only in daemon mode

            if (Worker::$daemonize === false)

            {

                // chek mtime of files per second 

                Timer::add($this->_interval, [$this, 'monitor']);

            }

        };

    }



    //监听器，kill进程

    public function monitor ()

    {

        // recursive traversal directory

        $iterator = new RecursiveDirectoryIterator($this->_monitor_dir);

        $iterator = new RecursiveIteratorIterator($iterator);



        foreach ($iterator as $file)

        {

            // only check php files

            if (pathinfo($file, PATHINFO_EXTENSION) != 'php') continue;



            // check mtime

            if ($this->_last_time < $file->getMTime())

            {

                exec('taskkill -f -pid '. getmypid());

                $this->_last_time = $file->getMTime();

                return true;

            }

        }

    }

}

把gatewayworker示例文件start_for_win.bat替换为如下代码，即可自动识别项目中的start_开头的php文件，仅限windows。

代码中的YourApp为你的项目文件夹

@echo off

setlocal enabledelayedexpansion

set app=Applications\YourApp

for /f "delims=" %%i in ('dir %app%\start_*.php /b') do (

        set FILES=!FILES! %app%\%%i

    )

php !FILES!
