查找当前网址
当前 URL 由您的 Web 服务器提供并写入 $_SERVER
超级全局.运行这个小脚本,<?php echo '<pre>';print_r($_SERVER);
,通过你的服务器和 root 来找到你正在寻找的值.
The current URL is supplied by your web server and written to the $_SERVER
super-global. Run this small script, <?php echo '<pre>'; print_r($_SERVER);
, through your server and root around to find the value(s) you are looking for.

在 TWIG 中获取 URL
获得 URL 后,在 Twig 模板实例上调用 render(...)
时,需要将其作为模板变量传递.例如,您可以编写此代码.
After you have the URL, you need to pass it as a template variable when calling render(...)
on the Twig template instance. For example, you might code this.
$current_url = // figure out what the current url is
// pass the current URL as a variable to the template
echo $template->render(array('current_url' => $current_url));
要在模板中使用变量,请使用 {{ variable_name }}
语法.
To use the variable in the template, you use the {{ variable_name }}
syntax.
