workerman的Timer定时器类的定时器注意事项-多进程的进程安全（并发问题）

发布时间：2021-12-05 00:17:38编辑：雪饮阅读（）

多进程设置了，定时任务可能会造成并发问题，例如下面的代码每秒会打印5次。

<?php

use Workerman\Worker;

use Workerman\lib\Timer;

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

$worker = new Worker();

// 5个进程

$worker->count = 5;

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

// 5个进程，每个进程都有一个这样的定时器

Timer::add(1, function(){

echo "hi time:".date("H:i:s",time())."\r\n";

});

};

Worker::runAll();

// 运行worker

Worker::runAll();

实例运行：

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

Workerman[test.php] start in DEBUG mode
