workerman-filemonitor只能用于linux，但是我們平時(shí)開發(fā)都是用的windows?；趙orkerman-filemonitor二次修改，可完美實(shí)現(xiàn)windwos開發(fā)時(shí)的代碼熱更新。

經(jīng)過測(cè)試，windows下不能直接在filemonitor啟動(dòng)的進(jìn)程中獲取我們需要的父進(jìn)程，所以需要在你啟動(dòng)的gateway文件中添加如下代碼（該代碼一定要放在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
 *
 * 監(jiān)控文件更新并自動(dòng)reload workerman
 *
 * 使用方法:
 * require_once __DIR__ . '/FileMonitor.php';
 * new FileMonitor($worker, $dir, $timer);

class FileMonitor
{
    //待監(jiān)聽的項(xiàng)目目錄
    private $_monitor_dir = '';

    //熱更新間隔時(shí)間,默認(rèn)3s
    private $_interval = 0;

    //最后一次同步時(shí)間
    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']);
            }
        };
    }
