Need help in designing this application using HTML and PHP code.

Create a professional looking PHP web application for Jazz Pizza. This application should allow users to order pizza through the online ordering system based on the following:

Number of Pizzas to Order (constraint all pizzas ordered must be the same)

Size Small ($5.00 each), Medium ($7.00 each), or Large ($9.00 each)

Crust Deep Dish ($2.00 extra for each), Traditional, Thin

Toppings: Pepperoni, Bacon, Sausage, Ham, Mushrooms, Onions, Olives, Tomatoes, Green Peppers (1st topping is free, $1.00 for each additional topping per pizza)

Delivery or Pickup $2.50 charge for delivery Users will need to enter a delivery address if they choose delivery

Addition details:

Students receive a 15% discount

Sales tax of 10% is added to the sub-total (after discounts)

The application should include an Index.php file that allows for users to input their ordering information and a Receipt.php file that displays a complete receipt to the user. The receipt must include the details of the order (number and size of pizza(s), type of crust, complete list of toppings, discounts, sub-total, tax amount, and total price).
