don't know but i think try this part of what you have not sure but give it a try

 

if($_SESSION['cart']) {
	$product_id=0;
	switch($action) {
		case "add":
                        $product_id++;
			if (isset($_SESSION['cart'][$product_id])){ 
          				 $_SESSION['cart'][$product_id];}
         			else 
           						{$_SESSION['cart'][$product_id]=1;}
            break;

		case "remove":
                        $product_id = $product_id -1;
			if (isset($_SESSION['cart'][$product_id]))
					 $_SESSION['cart'][$product_id];
					 if ($_SESSION['cart'][$product_id]==0)
					 	unset($_SESSION['cart'][$product_id]);
		break;

		case "empty":
			unset($_SESSION['cart']);  
		break;
		}
}

you may also have to unset() the session before renaming it
