Just use [url=www.php.net/preg_match]preg_match[/url] to check for ^p\d+$ or ^p(\d+)$ if you want to work on the numeric part.

i've managed to do this: if (!preg_match('/[[:^digit:]]/', $username)) { } but this only detects if it is a number, how can i determine if it also begins with a letter p ?

As I said, use ^p\d+$ as the regexp (that's [[:^digit:]] in your example) to check for that. the ^ matches at the beginning of the string, and $ at the end, so that'll let p123 through, but not p123a or ap123.
