Using the controller context in a view

Yii views are pretty powerful and have many features. One of them is that you can use the controller context in a view. So, let's try it.

Getting ready

Create a new application using the Composer package manager, as described in the official guide at http://www.yiiframework.com/doc-2.0/guide-start-installation.html.

1. Create a controllers/ViewController.php as follows:

   <?php
   
   namespace app\controllers;
   
   use yii\web\Controller;
   
   class ViewController extends Controller
   {
       public $pageTitle;
   
       public function actionIndex()
       {
           $this->pageTitle = 'Controller context test';
   
           return $this->render('index');
       }
   
       public function hello()
       {
           if (!empty($_GET['name'])) {
               echo 'Hello, '  . $_GET['name'] . '!';
           }
       }
   }

2. Now, we will create a views/view.php showing what we can do:

   <h1><?= $this->context->pageTitle ?></h1>
   <p>Hello call. <?php $this->context...
