How to make a regex for files ending in .php?

Question

I\'m trying to write a very simple regular expression that matches any file name that doesn\'t end in .php. I came up with the following...

(.*?)(?!\\.php)$         


        

Answer 1

You are at the end of the string and looking ahead. What you want is a look behind instead:

(.*)$(?

Note that not all regular expression engines support lookbehind assertions.
