Your job is to write the file "php_assignment1.php", to accomplish the tasks described below. I have written my own version that you can play with. PHP is a server-side language, so you can use my program without being able to see my PHP code--I guess you'll just have to write your own.
Several of the descriptions below have hints that refer to PHP functions. You can view the reference information for those functions at http://www.php.net/.
