PHP多进程并行执行php脚本详解编程语言

<?php 
 
//fork.php
 
$cmds = [ 
    '/data/wwwroot/default/test1.php', 
    '/data/wwwroot/default/test2.php', 
    '/data/wwwroot/default/test3.php'

foreach($cmds as $cmd) { 
    $pid = pcntl_fork(); 
    if ($pid == -1) {  
        //进程创建失败 
            echo '创建子进程失败时返回-1'; 
            exit(-1); 
        } 
        else if($pid) {  
        //父进程会得到子进程号，所以这里是父进程执行的逻辑 
            pcntl_wait($status,WNOHANG); 
        } 
        else{  
        //子进程处理逻辑 
            echo getmypid() , " /r/n"; 
            sleep(20);// 保持20秒，确保能被ps查到 
 
            pcntl_exec('/usr/local/php/bin/php',$cmd); 
            exit(0); 
        }
