twigHow to use Slim with PHP Twig?

Slim is a PHP micro-framework that can be used with Twig, a template engine for PHP. To use Slim with Twig, you need to install the Slim-Views package.

composer require slim/slim-views

Once installed, you can configure Slim to use Twig as the default template engine.

$container['view'] = function ($container) {
    $view = new \Slim\Views\Twig(__DIR__ . '/../templates', [
        'cache' => false
    ]);

    // Instantiate and add Slim specific extension
    $basePath = rtrim(str_ireplace('index.php', '', $container['request']->getUri()->getBasePath()), '/');
    $view->addExtension(new Slim\Views\TwigExtension($container['router'], $basePath));

    return $view;
};

The code above configures Slim to use Twig as the default template engine. It also adds the Slim-specific Twig extension which allows you to use the urlFor function to generate URLs.

Parts of the code:

• $container['view']: This is the Slim container which holds the view configuration.
• new \Slim\Views\Twig: This instantiates a new Twig view.
• $basePath: This is the base path of the request.
• $view->addExtension: This adds the Slim-specific Twig extension.
