Fair enough, but in that case I think you want "!== false". The expression you have -- "($x != false)" -- will be true whether $x is 0, NULL, an empty string, an empty array, or actually FALSE. But "$x !== false" will only be true in the last case. Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
