Write a Php application that is used to manage a restaurant business. Assume menu items, categories (appetizer, dessert ...etc), prices and descriptions. The Restaurant has 10 tables (labeled A thru J) and 5 wait staff. Assume all tables seat 6 patrons and all guests arrive in groups of 6 or less members. The application must provide the following two basic functions

1. Place order: This will start the process for a dinner party by assigning a table, waiter and the food order. Record this time as the start time.

2. Calculate total: This will end the dinner party by calculating the order total. Record this time as the end time.

Assume one waiter can serve two tables at a time.

In addition to providing ordering functionality, design a page for the Restaurant owner that provides the following information

1. Total Sales for a given period.

2. Table with top sales for a given period.

3. Table with maximum orders for a given period

4. Waiter/waitress with top sales for a given period.
