The instance of the className must be returned in the staticMethod, using "return new self" .
- Code example:
class clsShow {
  public static $url;

  public static function setData(){
    self::$url = '';
    return new self;

  public function show(){
    echo self::$url;

// accessing show() method after setData()
clsShow::setData()->show();             //
