[TOC] ## exec 以数组形式返回输出 ``` @exec("ps -ef | grep Up",$op); print_r($op); /* Array ( [0] => im_user 2640 1 0 17:05 ? 00:00:03 ./UpMessageServer [1] => im_user 2848 1 0 17:05 ? 00:00:01 ./UpOrgServer [2] => im_user 2945 1 0 17:05 ? 00:00:01 ./UpLoginServer ) */ ``` ## 系统命令如运行失败,使用觉得路径 ``` bad @exec("ip addr", $return_array); good @exec("/usr/sbin/ip addr", $return_array); ```
