prefillGetAttributesObject() public static method

Is there any better way to initialize __get variables?
public static prefillGetAttributesObject ( &$object, $attrs = [], $attrRemove = [], $params = [] )
if (!empty($transferchatsDep)) {
    reset($transferchatsDep);

    }
}

$ReturnMessages['transfer_dep_chats'] = array('list' => array_values($transferchatsDep), 'last_id_identifier' => 'transfer_chat', 'last_id' => $lastPendingTransferID);
