kill function after specific time in php?

Question

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.

 <?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.

`timeout` sends a `term` signal: If the process won't respondi to a term, you can send a `kill` signal instead using `timeout -k 5 /usr...`. — Mark Baker, Mar 24 '14 at 08:19
@MarkBaker I want kill command automatically send to server if `exec()` not respond in give time. — Tomas, Mar 24 '14 at 08:24

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

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);

The command won't get killed and the execution finishes normally.You will get the O/P of command in $uptime variable. – Harikrishnan Mar 24 '14 at 12:02

Command will be killed at 5th second and return value will be `Killed command on time out` – Harikrishnan Mar 25 '14 at 10:06
Any method so command gives data, which it gets in first 5 second. – Tomas Mar 25 '14 at 10:10
sir this script return data after 5 second.I think it will kill the `sleep` process not the `exec`. – Tomas Mar 31 '14 at 11:45
