Hi i hav extended the mysqli class and want to add some further functionality to the static method i have created for creation of the database access object (see below). I want to add some further functionality however to read in the current website url and then point to a different database based on the url. When i try to add code into the static method looking for certain characters in the $_SERVER['HTTP_HOST'] global variable i get error messages:

Call to a member function query() on a non-object

I assume i cant call global verianbles in a static method perhaps? Any guidance on what th issue is and how i might solve?

PHP Code:


			
        public static function getInstance() {



            if (empty (self::$instance)) {

                self::$instance = new DataLayer(DB_HOST, DB_USER, DB_PASS, DB_DATABASE) or die("Cannot connect to MySQL server!");

            }



            return self::$instance;



        }
