                (
                    [0] => SimpleXMLElement Object
                        (
                            [room-id] => XXXXXX
                            [room-name] => XXXXXX

                        )

                    [1] => SimpleXMLElement Object
                        (
                            [room-id] => XXXXXX
                            [room-name] => XXXXXX
                            [room-status] => XXXXXX
                        )

                )

        )

    [status] => SimpleXMLElement Object
        (
            [code] => S002
            [description] => Request Executed Successfully.

Use it like this, because you indexex contains - :

$array_data->{"room-types"}->{"room-type"}
