I need help with a three step homework:

Lets practice working with control structures by modifying a PHP script. In Chapter 6 of our textbook we use the handle_reg.php file to demonstrate the use of if, switch, and loop statements. After working with the examples in the chapter, modify the handle_reg.php to do the following:

Rewrite handle_reg.php so that it uses a variable for the current year, instead of hard-coding that value. Name your file handle_reg_1.php

For debugging purposes, add code to the beginning of the handle_reg.php script that prints out the values of the received variables. Hint: Theres a short and a long way to do this. Name your file handle_reg_2.php

Update handle_reg.php so that it validates the users birthday by looking at the three individual form elements: month, day, and year. Create a variable that represents the users birthday in the format XX/DD/YYYY. Hint: Youll have to use concatenation. Name your file handle_reg_3.php

I need to submit the three modified PHP script files.
