You can find anything on that topic on the type hint section. If you use type hinting: Classname $a, $a can only be instance of Classname, nothing else. But if you want to allow null as well, you have to write Classname $a = null, Don't mistake this as default value! It is _meant_ as "Classname or null" are allowed. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
