return $this->redirect(['site/index']);
}
```

As you can see when the language is changed, redirection to site/index happens. Also mind that we are not modifying the attribute from config/web.php using Yii::$app->language, but we are saving the value into the session. The reason is that PHP deletes memory after every click, only session is kept. We then can use the value in other controllers and views like this:
 
 
```php
 
Yii::$app->language = Yii::$app->session->get('langID');
 
```
 
 
using method beforeAction:
 
 
```php
 
    public function beforeAction($action) {
 
 
        if (!parent::beforeAction($action)) {
 
            return false;
 
        }
 
 
        Yii::$app->language = Yii::$app->session->get('langID');
 
 
        return true;
 
    }
 
```
 
 
.. or you can create one parent-controller named for example BaseController. All other controllers will extend it.
 
 
```php
 
<?php
 
 
namespace app\controllers;
 
 
use Yii;
 
use yii\web\Controller;
 
 
class BasicController extends Controller {
 
 
    public function beforeAction($action) {
 
 
        if (!parent::beforeAction($action)) {
 
            return false;
 
        }
 
 
        Yii::$app->language = Yii::$app->session->get('langID');
 
 
        return true;
 
    }
 
 
}
