在php中具体时间后杀掉函数？

I have five exec() function in my script.I want if any function will not give any response in given time function will kill and then next function starts its execution.

我的脚本中有五个exec()函数。我想如果任何函数在给定时间内不给出任何响应函数将kill,然后下一个函数开始执行。

 <?php

   exec("timeout 5 /usr/local/bin/wrun 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat'",$uptime);  
   exec("timeout 5 /usr/local/bin/trun 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat'",$uptime);  
   exec("timeout 5 /usr/local/bin/drun 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat'",$uptime);

 ?>

In this timeout argument not working.Please correct this or gives any alternative method.

在此超时参数不起作用。请更正此或提供任何替代方法。

Create a bash script caller.sh and execute it via exec. The command will be automatically killed after 5 seconds.

创建一个bash脚本caller.sh并通过exec执行它。该命令将在5秒后自动终止。

caller.sh

#!/bin/sh
/usr/local/bin/wrun 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat' &
sleep 5
kill $! 2>/dev/null && echo "Killed command on time out"

PHP

exec("caller.sh",$uptime);
