What role can template engines like Twig or libraries like GNU gettext play in simplifying the management of multilingual content in PHP applications, particularly when dealing with complex HTML templates?

Managing multilingual content in PHP applications can be complex, especially when dealing with complex HTML templates. Template engines like Twig or libraries like GNU gettext can simplify this process by allowing developers to separate the presentation layer from the content, making it easier to manage translations and language-specific formatting within the templates. 

// Example of using Twig for managing multilingual content in PHP

// Include Twig autoloader
require_once 'vendor/autoload.php';

// Initialize Twig
$loader = new Twig_Loader_Filesystem('path/to/templates');
$twig = new Twig_Environment($loader);

// Set language based on user preference or session
$language = 'en';

// Load translations for the selected language
$translator = new GettextTranslator();
$translator->load('path/to/translations/' . $language . '.mo');

// Render template with translated content
echo $twig->render('template.twig', [
    'title' => $translator->gettext('Hello'),
    'content' => $translator->gettext('Welcome to our website')
]);
