Using === should work. This is most likely because, if I remember correctly, when you compare a string to a integer, it essentially does an intval(string). If the string contains no numbers, you end up with nothing.. or zero. It definitely isn't a bug and definitely has to do with type conversion though. the triple equalsign deal should work since it forces PHP not to convert types. -TG = = = Original message = = = >> No, Christopher, that is not a bug.
