Q1. rewrite the exercise on April 4 by adding the following operations:

1) In the php script, create an associative array named $order that stores the following values:

- the number of cheese toppings;

- the number of pepperoni toppings;

- the number of ham toppings;

- the size of the ordered pizza;

- the number of the ordered pizza;

- the total cost of the order;

- the discount rate;

- the total cost after the discount.

2) the script assigns the values collected from the following fields:

- the number of each topping;

- the size of the ordered pizza;

- the number of the ordered pizza;

as the values of the elements of this array.

3) after calculating the total cost for an order, add the following values as the values of the elements of this array:

- the total cost of the order;

- the discount rate;

- the total cost after the discount;

as the values of the elements of this array.

4) applying foreach loop to print each element (key and value) of the associative array as a table. The text alignment, font size, and text color will be specified by a embedded css script that is generated by the php script.
