if(isset($_GET['product_id'])) {
    $product_id = $_GET['product_id'];

    // Check if product is already in cart
    if(isset($_SESSION['cart'][$product_id])) {
        // Increment quantity if product is already in cart
        $_SESSION['cart'][$product_id]['quantity']++;
    } else {
        // Add product to cart with quantity 1
        $_SESSION['cart'][$product_id] = array('quantity' => 1);
    }

    echo "Product added to cart!";
}
?>
