Yes, it was just a pseudo-code and not a true singleton implementation.

Would it work if instance is saved inside a local static var like:

public static function getInstance() {

  static $instance = NULL;

  if (is_null($instance)) {
    $instance = new self();
  }

  return $instance;
}
