本文实例讲述了PHP+shell实现多线程的方法。分享给大家供大家参考。具体如下:
这里介绍如何借助shell脚本实现多线程。
先写个简单的php代码,这里为了让脚本执行时间更长,,方便看效果,sleep一下,呵呵!先看下test.php的代码:
PHP代码:
在看下shell脚本的代码,非常简单
#!/bin/bash for i in 1 2 3 4 5 6 7 8 9 10 do /usr/bin/php -q /var/www/html/test.php & done
注意到在请求php代码的那行有一个&符号吗,这个是关键,不加的话是不能进行多线程的,&表示讲服务推送到后台执行,因此,在 shell的每次的循环中不必等php的代码全部执行完在请求下一个文件,而是同时进行的,这样就实现了多线程,下面运行下shell看下效果,这里你将 看到10个test.php进程再跑,再利用linux的定时器,定时请求这个shell,在处理一些需要多线程的任务,例如,批量下载时,非常好用!
希望本文所述对大家的php程序设计有所帮助。
