onWorkerStart

说明:

callback Worker::$onWorkerStart

设置Worker子进程启动时的回调函数，每个子进程启动时都会执行。

注意：onWorkerStart是在子进程启动时运行的，如果开启了多个子进程($worker->count > 1)，每个子进程运行一次，则总共会运行$worker->count次。

回调函数的参数

$worker

即Worker对象

实例：

<?php

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:8484');

$worker->count=2;

$worker->onWorkerStart = function(Worker $worker)

{

echo "Worker starting...\n";

};

// 运行worker

Worker::runAll();

实例运行：

[root@izj6c2jeancylo0ppo4vz5z workerman]# php test.php start
