Write a PHP program that displays an order form. The order form should list six products. Next to each product name there should be a text box into which a user can enter how many of that product she wants to order. When the form is submitted, the submitted form data should be saved into the session. Make another page that displays the order confirmation page which displays the contents of the saved order and a link to Check Out. When the Check Out link is clicked, the order should be cleared from the session.
