foreach in models and controller

Don't use `echo` in model.

What should I use?

If you call `echo`, it outputs at the moment.
So you should call echo only in views (but it seems you don't use views).

You have to return data from model, instead of echo.

I can try edit 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 = $db->get('');
        foreach ($query_info_view->result() as $row){
            return $row->value;
        }
    } 


But in this way It does not work anyway. I do not print variables above code, but it makes me even use.
