Symfony Templating (Twig)

Twig is a modern template engine for PHP

  • Fast: Twig compiles templates down to plain optimized PHP code. The overhead compared to regular PHP code was reduced to the very minimum.
  • Secure: Twig has a sandbox mode to evaluate untrusted template code. This allows Twig to be used as a template language for applications where users may modify the template design.
  • Flexible: Twig is powered by a flexible lexer and parser. This allows the developer to define its own custom tags and filters, and create its own DSL.

Génération des URLs : Doc de Référence : https://symfony.com/doc/current/templating.html#linking-to-pages Nous allons maintenant mettre en place la navigation inter-pages de notre site. Accueil Ici, la fonction url() va demander à Symfony de créer une URL absolue pour la route index. Le résultat après compilation sera alors : Accueil Lorsqu’il y à des paramètres, nous procédons de la façons suivantes : Business Ce qui donnera : Business
