How can PHP developers ensure that the correct article is added to the shopping cart when multiple items are listed in search results?

To ensure that the correct article is added to the shopping cart when multiple items are listed in search results, PHP developers can include a unique identifier for each item in the search results. This identifier can then be passed along with the item when adding it to the shopping cart to ensure the correct item is added. 

// Sample code snippet to add item to shopping cart with unique identifier
$item_id = $_POST['item_id']; // Unique identifier for the item
$item_name = $_POST['item_name']; // Name of the item
$item_price = $_POST['item_price']; // Price of the item

// Add item to shopping cart with unique identifier
$_SESSION['cart'][$item_id] = array(
    'name' => $item_name,
    'price' => $item_price
);
