how start a second shell script

[sugram]

Hello

I have a php script that is executed a shell Script after a click.
That works fine.

is it possible that another shell script is executed after a waiting period?

<?php

if ($_GET['run']) {

  $script = "sudo /home/pi/midori-restart.sh";

  $run=`$script`;

}

?>

<style type="text/css">
a { color: #ffffff; text-decoration: none; }
</style>

<a href="?run=true">Display restart</a>
