Why regex? Wouldn't you rather use globbing when looking for files?

^wp.*.php$ Should do the trick.
The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

@AdamHowell+and*are both greedy, although greediness doesn't make a difference in this case. The difference is that*matches zero or more characters, and the+matches one or more characters. So if someone wanted to match "wp.php", they should use*; if they specifically wanted to not match that, they should use+.
