There are no great surprises in this script. If the cart is empty, the script will notify the cus-
tomer; otherwise, it will display the form shown in Figure 25.8.
If a user continues by clicking the Purchase button at the bottom for the form, she will be taken
to the purchase.php script. You can see the output of this script in Figure 25.9.
