Learn them. They look scary but once you get used to them they're a godsend.

This one makes sure a string begins with "message" and is followed by a number:
Code:
/^message[0-9]*$/
Looks complex but it means "if the string has nothing but beginning with "message" and then followed by any number of digits and that's it".

preg_replace() is even more fun. It has the power to match and extract substrings from your match string that can be used within the replace string.
