If I misunderstood the intval part of your post, than the [proposed already] is_numeric solutions are the way to go. is_numeric will, however, unlike the conversion functions, return false if there's anything but a number in the string, so, i.e., is_numeric ("10a1") will return false, but intval ("10a1") will give "10". -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
