What are some potential drawbacks of using multiple cookies to store order information in PHP?

One potential drawback of using multiple cookies to store order information in PHP is that it can make the code more complex and harder to maintain. Additionally, storing sensitive order information in cookies can pose a security risk if the cookies are not properly encrypted or validated. To address this issue, consider using a server-side session to store order information securely and efficiently.

// Start a session to store order information
session_start();

// Store order information in session variables
$_SESSION['order_id'] = 12345;
$_SESSION['order_total'] = 50.00;
$_SESSION['order_items'] = ['item1', 'item2', 'item3'];
