I want to use GET in PHP and I know how to. The only problem is when I start my page I dont have a ?var=... on it. For example my site is
http://localhost/q/question.php
and in my code is
$num = $_GET['num'];
And I want to assume that if $num == NULL or has not been defined as in the link above.
I will generate a different page. because as example below just determines I am starting the questions in what ever page.
No num variable = Start Generating questions in array.
http://localhost/q/question.php?num=1
