RE: [PHP] Can't remove an element from an array

You have two separate problems here: 1) unset($_SESSION["cart_array"], $item) This unsets $_SESSION["cart_array"] and also $item, it should be unset($_SESSION["cart_array"][$item]) 2) The method of unsetting session variables depends on whether you have register_globals on, it's all here: http://www.php.net/manual/en/ref.session.php . The Examples section has detailed examples that should help you fix your problem > -----Original Message----- > From: Brian Dunning [mailto:brian@briandunning.com] > Sent: Thursday, February 19, 2004 8:50 AM > To: php-general@lists.php.net > Subject: [PHP] Can't remove an element from an array > > > Hi, I have an array that holds the item_id's for a shopping cart.
