Silex的航线？

one simple question: how do I get working linebreaks in Silex?

Following code will get me the output

This ist a Text.<br> Next Line

.

$app->get('', function () use ($app) {

  $content= 'This ist a Text. <br> Next Line';

  return $app['twig']->render('index.html.twig', array(
    'content' => $content
  ));
});

How do i get a working linebreak?

By default, twig escapes everything. You can switch off escaping (not recommend) or you can use the raw filter when echoing:

{{ content|raw }}

However, another approach would be to use a linebreak instead of the BR element and then use the nl2br filter,
