PHP grep search without console access

With some cPanel setups, no SSH or console access is provided. If you want to do a simple file search, it's kinda tricky!

Luckily, most installs don't block the shell_exec function, so you can use PHP to execute a grep search through a shell.
<?php
$shellCommand = "grep 'mytext' * -R";
echo shell_exec($shellCommand);
?>
