php

I have a MySQL database with some URLs in it. One URL per row. Each URL has my script on it. What I am wanting to do, is check if the file is still there via a PHP script. Not check if it 404'd, but rather check if it has been modified or replaced. Is this possible? If so, how would it be accomplished?
