$loader = new Twig_Loader_Filesystem('/path/to/templates'); $twig = new Twig_Environment($loader); $template = new Twig_Template($twig, 'template.html.twig');In this example, a Twig_Loader_Filesystem is created with the path to the directory where templates are stored. A new instance of Twig_Environment is created using the loader. Finally, a new instance of Twig_Template is created with the environment and the name of the template file. The Twig_Template __construct method is part of the Twig package library, which is a popular template engine for PHP used in many web frameworks and content management systems.
