The method hasChildren() does not exist on TomPHP\ConfigServiceProvider\ConfigIterator. Did you maybe mean callHasChildren()?

            array_push($this->path, parent::key());

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);
    }
}
