Re: Casting Weirdness - Possible PHP BUG?

D0h! Now I change: $value1 = (string) $value1; To: $value1 = settype($value1, "string"); and it works. Anyone have a clue what is happening here? I know I can use either of the following: $value1 = settype($value1, "string"); $value1 = strval($value1); $value1 = (string) $value1; There seems to be something different with each method, but what...?.. Anyway, I know this should be on a different group, but for some reason I'm having trouble posting anywhere else. "Jeremiah J.
