原文：Twig in Drupal 8

Twig 是PHP的一个模板引擎，是Symfony2框架的一部分。

在Drupal 8中，Twig代替PHP模板而成为默认的模板引擎。这种变化的结果之一是，所有 theme_* 函数和基于 PHP 模板的 *.tpl.php 文件都由 *.html.twig 模板文件所代替。

Twig is a template engine for PHP and it is part of the Symfony2 framework.

In Drupal 8 Twig replaces PHPTemplate as the default templating engine. One of the results of this change is that all of the theme_* functions and PHPTemplate based *.tpl.php files have been replaced in by *.html.twig template files.
