The overhead compared to regular PHP code was reduced to the very minimum. </li>     <li><strong>安全</strong>: Twig has a <em>sandbox</em> 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. </li>     <li><strong>灵活</strong>: Twig is powered by a flexible <em>lexer</em> and <em>parser</em>. This allows the developer to define its own custom tags and filters, and create its own DSL. </li>    </ul>    <p></p>    <p>示例模板：</p>    <p>{% extends "layout.html" %}<br /> <br /> {% block content %}<br />   Content of the page...<br /> {% endblock %}</p>    <br />    <p><strong>项目主页：</strong><a href="http://www.open-open.com/lib/view/home/1322983785765" target="_blank">http://www.open-open.com/lib/view/home/1322983785765</a></p>
