How can the PHP code be modified to ensure that the shopping cart is cleared properly when choosing to delete items?

To ensure that the shopping cart is cleared properly when choosing to delete items, we can modify the PHP code by adding a condition to check if the "delete" action is triggered. If the "delete" action is detected, we can unset the session variable that stores the cart items. 

<?php
session_start();

if(isset($_GET['action']) && $_GET['action'] == 'delete') {
    unset($_SESSION['cart']);
}

// Other code for adding items to the cart, displaying the cart, etc.
?>
