Are there any best practices for designing and implementing a template system in PHP?

When designing and implementing a template system in PHP, it is essential to separate the presentation layer from the business logic to ensure maintainability and reusability. One best practice is to use a templating engine like Twig or Blade to keep the PHP logic separate from the HTML markup. Additionally, creating reusable template partials and layouts can help streamline the development process and improve code organization.

// 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' => 'Homepage', 'content' => 'Welcome to our website']);
