preg_replace(‘#\W#’, ”, $string) – simple, easy, effective… awesome man, been struggling this for ages today. A pretty cool tool for this is RegExBuddy – worth checking out if you ever need to build / test regexes and cant be bothered to do it using php.

Maybe I don’t quite get what you are after, but if you just want to be left with alphanumeric characters then wouldn’t you use w?

eg:
preg_replace(‘#\W#’, ”, $string)
