<?php

class View
{
    public function render($name)
    {
        echo "Rendering view $name";
    }
}

class ControllerWithInheritance extends View
{
    public function index()
    {
        $this->render('index');
    }
}

class ControllerWithComposition
{
    private $view;

    public function __construct(View $view)
    {
        $this->view = $view;
    }

    public function index()
    {
        $this->view->render('index');
    }
}

$controllerWithInheritance = new ControllerWithInheritance();
$controllerWithInheritance->index();

$controllerWithComposition = new ControllerWithComposition(new View());
$controllerWithComposition->index();

// Output:
// Rendering view index
// Rendering view index
