/**
* ErrorAction displays application errors using a specified view.
*
* To use ErrorAction, you need to do the following steps:
*
* First, declare an action of ErrorAction type in the `actions()` method of your `SiteController`
* class (or whatever controller you prefer), like the following:
*
* ```php
* public function actions()
* {
* return array(
* 'error' => array(
* 'class' => 'yii\web\ErrorAction',
* ),
* );
* }
* ```
*
* Then, create a view file for this action. If the route of your error action is `site/error`, then
* the view file should be `views/site/error.php`. In this view file, the following variables are available:
*
* - `$name`: the error name
* - `$message`: the error message
* - `$exception`: the exception being handled
*
* Finally, configure the "errorHandler" application component as follows,
*
* ```php
* 'errorHandler' => array(
* 'errorAction' => 'site/error',
* )
* ```
