Code (PHP)
<?php
session_start();
//Create 'cart' if it doesn't already exist

'price' => $_POST['price'],
//Qty wanted of item
'qty' => $_POST['qty']
);
//Add this item to the shopping cart
$_SESSION['SHOPPING_CART'][] = $ITEM;
//Clear the URL variables
header('Location: ' . $_SERVER['PHP_SELF']);
}
//Allowing the modification of individual items no longer keeps this a simple shopping cart.
//We only support emptying and removing
else if (isset($_GET['remove'])){
//Remove the item from the cart
unset($_SESSION['SHOPPING_CART'][$_GET['remove']]);
