Views in MVC in PHP

Let's now add views to our actions. According to the rules of our framework, views are stored in the folder /project/views/.

Furthermore, our framework follows a convention: the name of the view file must match the name of the action and be placed in a folder with the same name as the controller. For example, if we have a controller PageController, then all its views should be stored in the folder /project/views/page/. The view file itself must have the extension .php. For instance, if the controller PageController has an action act, then its view should be located at /project/views/page/act.php.

In order to assign a view to an action, that action must call the method render, passing it the name of the view as a parameter. The view name must consist of the controller name in lowercase, followed by the action name after a /.

The method render does not need to be implemented in the controller - it is inherited from the parent class Core\Controller. Moreover, for correct operation, the result of the method should be returned via return.

So, let's say we have a controller Page with an action act. Let's bind a view to this action:

project/controllers/PageController.php<?php
  namespace Project\Controllers;
  use Core\Controller;
  
  class PageController extends Controller
  {
    public function act()
    {
      return $this->render('page/act');
    }
  }
?>

Now let's create the file with the HTML code of our view:

/project/views/page/act.php<div>
  this is the view
  for the act action of the page controller
</div>
