Make any url call the same script

I’d like any url request to call one script.

www.website.co.uk/parent-directory/YYYY/MM/DD/unique-file.php

I could create a small require() file for each page, but I’m sure there is a way to have any file be handled by a script in the “parent-directory”, without creating the “unique-file.php” in advance.

Can you help?
