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：
复制代码 代码如下:
#!/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);
}
}
