foreach in models and controller

I can try to edit the model in this way:

PHP Code:

public function info_server($name) {
        $db = $this->load->database('site', TRUE);
        $db    ->select('value')
                        ->from('arcor_server_setting')
            ->where('name', $name);
        $query_info_view = $db->get('');
        $row = $query_info_view->row();
        echo $row->value;
    } 


I also tried to remove the echo.But it does not solve the problem. The tag is not read dovre but should be printed first.
