help on shopping cart class

[airdee]

hi all! i got this shopping cart class script from another website. the cart prints individually like this:

[code=php:0]
$obj_cart->add_itemsToCart($pcode,$pname,$price);
$obj_cart->add_itemsToCart($pcode,$pname,$price);
$obj_cart->add_itemsToCart($pcode,$pname,$price);
....and so on
[/code]

Sample Output:
1. 001    Tootsie Roll    $.55
2. 005    Marsh Mallow  $.35
3. 010    White Rabbit    $.55
...and so on.

I want to print the items dynamically like using an array or so []. That when a user click the 'add to cart link', the cart will get updated each time the link is clicked. How can I make it dynamically? Thanks for any help you can give me!
