? is_null returns true if the variable exists and is NULL and throws a notice if the variable is not set WHY is that fact COMPLETELY IRRELEVANT? Just because you don't think people should be coding in the way that it causes problems with existing code does not make it irrelevant we have to put up with the notices because there is no CLEAN way to establish that a variable exists only that it is set. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
