It seems like you call parent on a different method (key() instead of next()). Are you sure this is correct? If so, you might want to change this to $this->key().

        }

        parent::next();
    }

    public function rewind()

        $this->path = [];

        parent::rewind();

    public function endChildren()
    {
        array_pop($this->path);
    }
}
