    Purpose:Chapter 6 Exercise

    REQUIREMENT: Write a Web-based application consisting of a Web form
    (Modify3.html) and a PHP progam (Modify3.php).

    Modify3.html includes a form that consists only of a Submit button
    When the button is pressed, Modify3.php runs and opens the file
    tickets.txt which contains a list of three ticket orders.
    The program reads the ticket order on the first line, multiplies this
    by 6.50 (the price of each ticket) to get the cost of the sale, and
    displays the cost of the sale.

    Modify Modify3.php so that it reads and displays all three ticket orders
    and displays the cost of each sale AND also the total sales.
