PHP多進程並行執行php腳本

<?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) { //進程創建失敗
            echo '創建子進程失敗時返回-1'; exit(-1); } else if($pid) { //父進程會得到子進程號，所以這里是父進程執行的邏輯
 pcntl_wait($status,WNOHANG); } else{ //子進程處理邏輯
            echo getmypid() , " \r\n"; sleep(20);// 保持20秒，確保能被ps查到
 pcntl_exec('/usr/local/php/bin/php',$cmd); exit(0); } }

# php fork.php  //使用php cls模式執行運行fork.php
