I'm thinking a more viable solution would be to do something like: mixed preg_match ( mixed pattern, string subject [, array matches [, int flags]]) if pattern is an array, preg_match will cycle through each one till a match is made; returns the index of the array passed (that matched) or false if not found. This should also be BC if you just pass one string.
