由於php的程序是不支援多執行緒的，有些場景為了方便以及提高效能，可以用php實現多程序以彌補這個不足：

#!/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){ //程序建立失敗
                die('fork child process failure!');
        }
        else if($pid){ //父程序處理邏輯
                pcntl_wait($status,WNOHANG);
        }
        else{ //子程序處理邏輯
                pcntl_exec('/usr/local/bin/php',$cmd);
        }
}
