Question

http://localhost:8888/test.php

I typed in the above URL to navigate to a blank php file I’d created, and my friend typed the following in my URL bar:

?one=3&two=18 

(after /test.php)

He said that when I refresh the page, he wants to see the number 21 show up. I’m not entirely sure where to start. Any help for this PHP beginner is appreciated.

Thanks!

Try this…

<?php

if (isset($_GET['one']) AND isset($_GET['two'])) {

    $one = (int) $_GET['one'];

    $two = (int) $_GET['two'];

    echo $one + $two;

}
