我试过这样做：

但这仍然不起作用。

The only variables available in Twig are:
Twig 中唯一可用的变量是：
- the ones you pass through the second parameter of Twig_Environment#render()
- the ones you pass by calling Twig_Environment#addGlobal()
- 你通过Twig_Environment#render()的第二个参数传递的那些
- 您通过调用Twig_Environment#addGlobal()传递的那些
If you wish to have a pagevariable available, add "page" => $_GET["page"]to the second parameter of render.
如果您希望有一个page可用的变量，请添加"page" => $_GET["page"]到 的第二个参数render。
If you wish to have the complete $_GETsuperglobal available, add "GET" => $_GETto the second parameter of render.
如果您希望获得完整的$_GET超全局变量，请添加"GET" => $_GET到render.

You cannot access raw PHP values in TWIG so you must attached anything that you need to the twig object.
您无法在 TWIG 中访问原始 PHP 值，因此您必须将所需的任何内容附加到树枝对象。
Here is an example of attaching the $_GET, $_POSTand $_SESSIONto twig.
这是将$_GET,$_POST和附加$_SESSION到树枝的示例。
//initialise your twig object
$loader = new \Twig_Loader_Filesystem(__PATH_TO_TEMPLATES_FOLDER__');
$this->twig = new \Twig_Environment($loader);
$this->twig->addGlobal('_session', $_SESSION);
$this->twig->addGlobal('_post', $_POST);
$this->twig->addGlobal('_get', $_GET);
Now lets assume you have a value called usernamestored in each of the above ($_GET, $_POSTand $_SESSION)
You can now access all of these inside your template as follows.
现在让我们假设您username在上面的每个 ( $_GET,$_POST和$_SESSION) 中都有一个名为存储的值，您现在可以访问模板中的所有这些，如下所示。
{{ _session.username }}
{{ _post.username }}
{{ _get.username }}
Hope this helps
希望这可以帮助
