increment variable each time page gets called or opened?

Answer 1

No, because $q resets to 1 each time the page is called. You need some sort of persistence strategy (database, writing to a text file, etc) in order to keep track of the page views.

It's also a good idea to consolidate this functionality into a class, which can be used across your code base. For example:

class VisiterCounter {

    public static function incrementPageVisits($page){

        /*! 
         * Beyond the scope of this question, but would
         * probably involve updating a DB table or
         * writing to a text file
         */
        echo "incrementing count for ", $page;
    }

}

And then in newquestion.php,

VisiterCounter::incrementPageVisits('newquestion.php');

Or, if you had a front controller that handled all of the requests in your web application:

VisiterCounter::incrementPageVisits($_SERVER['REQUEST_URI']);
