How can PHP be effectively separated from templates in the MVC pattern to improve code maintainability?

To effectively separate PHP from templates in the MVC pattern, you can use a templating engine like Twig. This allows you to keep your PHP logic separate from your presentation layer, improving code maintainability and readability.

// Example using Twig templating engine
require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('templates');
$twig = new \Twig\Environment($loader);

$template = $twig->load('index.html');
echo $template->render(['title' => 'Welcome']);
