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

[Brian Dunning]

Hi, I have an array that holds the item_id's for a shopping cart. I am 
trying to remove the item specified by a GET like this:

foreach ($_SESSION["cart_array"] as $item) {
  if ($item==$_GET["item_id"]) {unset($_SESSION["cart_array"], $item); 
break;}
}

But it removes ALL items from the cart. And then when I view the cart 
on the next page, EVERYTHING is back, including the item I tried to 
remove. What am I doing wrong? Thanks!
