Creating templates with TWIG

Symfony has its own template engine called TWIG. It is a simple scripting language with a few tags and only three main rules:

• Whatever goes between {% %} should be executed
• Whatever is expressed via {{ }} should be printed
• Whatever is enclosed by {# #} is just a comment

As we continue, we will see how to use TWIG to create sophisticated and dynamic templates based on our project needs. For now, let's just see what a TWIG file looks like.

The render() method from the previous topic has two parameters: the path to our TWIG template and its parameter. By default, all templates are in the app/Resources/views folder. If you go there, you will find another folder called default. That's why the middle part of the path parameter is default:

return $this->render('default/index.html.twig', [
      'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..'),
]);

Obviously, in the default folder...
