Download the attached For-statement PHP program file “sum_1_to_25_using_for.php” to a folder named “samples” in your nb9507 area. Copy it as well into a file “sum_1_to_25_using_while.php“.

Look up the syntax of the PHP statement WHILE on both w3schools.com and php.net.

Change the program in the sum_1_to_25_using_while.php file to use the PHP statement WHILE instead of For.

Rename the .php file appropriately for this change. Immediately after the opening “<? “, add a comment line with your name.
