Re: is_numeric for php3

Hi Daniel, No, I mean if it's numeric, not neccesarily an integer. As the following is numeric and not an integer but rather, a string : $num = '123'; Anyone have an authoritative answer on this? Like, something that would go in the manual as the official php3 is_numeric check?
