In the example you are providing $object and $_SESSION['object'] aren't even the same thing and unless something else is referencing $object then $object will be deleted. Now if what you meant was the following: $objectFoo = new MyObject(); $objectFee = &$objectFoo; unset( $objectFoo ); Then the object shouldn't be deleted since $objectFee is still referencing it. You will just break the reference. Correct me if I'm wrong *chuckle* Cheers, Rob. -- .-----------------. | Robert Cummings | :-----------------`----------------------------. | Webdeployer - Chief PHP and Java Programmer | :----------------------------------------------: | Mail : mailto:[EMAIL PROTECTED] | | Phone : (613) 731-4046 x.109 | :----------------------------------------------: | Website : http://www.webmotion.com | | Fax : (613) 260-9545 | `----------------------------------------------' -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
