PHP - Search for "X" in multiple PHP files

[Mathias]

Hello.

Does anyone know if there is an application, that can search for "X" text in multiple PHP files. I'm a bit of a PHP newbie, so I don't really know where to look for copyright text, banners and other things I'd like to get rid of.

I'm using PHPNuke.

TIA
