    public static $dbPass ;


    public function __construct() {  
        self::$dbHost = "<host name>";
        self::$dbUser = "<user name db>";
        self::$dbPass = "<pasword db>";
        }

   public static function getDbConnectionMySQL() {     
        return mysql_connect(self::$dbHost, self::$dbUser, self::$dbPass); //Connect to the databasse        
    }
    public static function getDbConnectionMySQLi() {
