Are there any PHP libraries or classes that are recommended for handling template replacement in PHP projects?

When working on PHP projects, it is common to need a way to handle template replacement, where placeholders in a template are replaced with actual values. This can be achieved using PHP libraries or classes that provide templating functionality. One recommended library for this purpose is Twig, a flexible and secure template engine for PHP.

// Example using Twig for template replacement
require_once 'vendor/autoload.php';

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

$template = $twig->load('template.twig');
echo $template->render(['name' => 'John Doe', 'age' => 30]);
