Delete items from shoppingcart

[arozzi]

I am new to PHP and don't really know the functions that well.
I have a shopping cart that is a multidimensional array that looks sth like this.

$product = array("ID"=>$id1, "name"=> $name1, "colour"=>$colour1, "quantity"=>$quantity1, "size"=>$size1, "price"=>$price1);

$cart[$pos] = $product;

I want to be able to delete an item from the cart but can't find any good way to do it.
One way I consider is using the unset function but then one position will be empty unless i restructure the array manually.
THis must be a common task to delete from carts so what is a good way to do it??

If the item is at the front of the array, array_shift() will do it.

If not, you might look at array_pop, and there's some other one....I forget the name.

I just ended up writing the following:

function compact_cart() {

if ($_SESSION['cart']) {
    for ($y=20; $y>0; $y--) {
       $x=($y-1);
       if (((empty($_SESSION['cart'][$x]) || (!($_SESSION  // watch cont...
['cart'][$x])))) && ($_SESSION['cart'][$y])){
           $_SESSION['cart'][$x]=$_SESSION['cart'][$y];
            unset($_SESSION['cart'][$y]);
                                }
                        }
}}

Works for carts up to 20 items, per the loop. A real ugly kludge, but I was REAL new at this at the time. Haven't thought about rewriting either...not that I'm not still a virtual noobie.... 🙂
