How can PHP developers optimize the process of reading and processing template files to improve performance and maintainability of their code?

Issue: PHP developers can optimize the process of reading and processing template files by using a template engine like Smarty or Twig. These template engines allow for separation of PHP logic and presentation, making the code more maintainable and improving performance by caching compiled templates. 

// Using Twig as a template engine
require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('templates');
$twig = new \Twig\Environment($loader, [
    'cache' => 'cache',
]);

$template = $twig->load('index.html');
echo $template->render(['title' => 'Hello, World!']);
