Answer 1

You can access this two ways since it is public...

class NoSuchRequestHandler implements Handler{ public static $TYPE = 2001; public static $VER = 0;

public function getType(){
  return self::$TYPE;  //not the "$" you were missing.  
}

public function getVersion(){
  return self::$VER;
}

}

echo NoSuchRequestHandler::$TYPE; //outside of the class.

Answer 2

PHP thinks you're trying to access a class constant because of:

return self::TYPE;

As Chris mentions, use:

return self::$TYPE;
