In a previous tutorial, we have created a session-based shopping cart by storing cart info in user session using PHP SESSION array. Shopping cart items in the session will be cleared at the time of logout or closing the window once the user closes his session.
This posts illustrates a relatively simple shopping cart in PHP using sessions to store cart details, quantities and total cart amount. The cart has an add to cart button , remove from cart button and displays the total value of the cart.
We need a session array to retain the data in different pages. Session arrays are like session variables which maintain a unique link between user's web page and the server.
