You need root to execute that command...

I suggest you configure it in sudo and execute it trough sudo

how i can configure it from sudo?

Execute as root:

visudo

enter the following lines:

Cmnd_Alias RES=/etc/init.d/iptables restart
apache ALL=NOPASSWD: RES

Save it... You must be familiar with Vim text editor.. visudo uses the same methods of editing...

Then you will be able to use:

$output=shell_exec('/usr/bin/sudo /etc/init.d/iptables restart');
