解析PHP实现多进程并行执行脚本

2015-01-24信息快讯网

本篇文章是对PHP实现多进程并行执行脚本进行了详细的分析介绍,需要的朋友参考下

由于php的进程是不支持多线程的,有些场景为了方便以及提高性能,可以用php实现多进程以弥补这个不足:

#!/usr/bin/env php
<?php
$cmds=array(
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php','mobile',1),
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php','mobile',2),
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php','click',1),
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php','click',2),
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php',1),
        array('/apps/bin/launcher.php','charge/promotion_props_stat.php',2)
);

foreach($cmds as $cmd){ $pid=pcntl_fork(); if($pid==-1){ //进程创建失败 die('fork child process failure!'); } else if($pid){ //父进程处理逻辑 pcntl_wait($status,WNOHANG); } else{ //子进程处理逻辑 pcntl_exec('/usr/local/bin/php',$cmd); } }
