How to use templates with Slim? - php

Question

http://www.slimframework.com/docs/tutorial/first-app.html shows using "plain old PHP" (Composer package is php-view and class is PhpRenderer) for templates as follows:
<?php
// Create app
$app = new \Slim\App();
// Get container
$container = $app->getContainer();
$container['view'] = new \Slim\Views\PhpRenderer("../templates/");
$app->get('/tickets', function (Request $request, Response $response) {
$this->logger->addInfo("Ticket list");
$mapper = new TicketMapper($this->db);
$tickets = $mapper->getTickets();
$response = $this->view->render($response, "tickets.phtml", ["tickets" => $tickets]);
return $response;
});
// Run app
$app->run();
The above page states using Twig for templates is basically the same, but http://www.slimframework.com/docs/features/templates.html shows a very different approach. Which is the correct way to use templates, and specifically how should I use Twig for templates?
<?php
// Create app
$app = new \Slim\App();
// Get container
$container = $app->getContainer();
// Register component on container
$container['view'] = function ($container) {
$view = new \Slim\Views\Twig('path/to/templates', [
'cache' => 'path/to/cache'
]);
$view->addExtension(new \Slim\Views\TwigExtension(
$container['router'],
$container['request']->getUri()
));
return $view;
};
// Render Twig template in route
$app->get('/hello/{name}', function ($request, $response, $args) {
return $this->view->render($response, 'profile.html', [
'name' => $args['name']
]);
})->setName('profile');
// Run app
$app->run();
