As you can see, typical controller contains actions that are public class methods named as `actionSomething`.
The output of an action is what the method returns. The return value will be handled by the `response` application
The output of an action is what the method returns, it could be rendered result or it can be instance of ```yii\web\Response```, for example:
```php
namespace app\controllers;
use yii\web\Controller;
use app\components\web\MyCustomResponse; #extended from yii\web\Response
class SiteController extends Controller
{
public function actionCustom()
{
/*
* do your things here
* since Response in extended from yii\base\Object, you can initialize its values by passing in
* __constructor() simple array.
*/
return new MyCustomResponse(['data' => $myCustomData]);
}
}
```
The return value will be handled by the `response` application
component which can convert the output to differnet formats such as JSON for example. The default behavior
is to output the value unchanged though.
