我有问题。我想在一个简单的HTML-DOM URL变量上传递我的Codeigniter Mysql变量（我可以在模板中使用{{ category:country }}使用此库http://simplehtmldom.sourceforge.net/）。没有结果我尝试了很多变化。
这是我的代码的开头：
<?php
include_once('simple_html_dom.php');
ini_set('display_errors', true);
error_reporting(E_ALL);
$url = 'http://address.com/".{{ category:country }}."/';
?>
我想打开地址，就像我得到德国变量一样，然后解析：http://address.com/germany。
非常感谢！

如果我正确理解了这个问题，那么你想要的可能是棘手的或不可能的。
基本上，简单的HTML DOM正在使用内存中的代码，因此当您提供$url时，它会尝试访问名为http://address.com/".{{ category:country }}."/的网址
模板解析器作用于PHP的输出缓冲区，因此在它准备好调用所有ob_* functions
之前不会调用它如果您的模板引擎支持它，那么您将需要执行以下操作：
<?php
include_once('simple_html_dom.php');
ini_set('display_errors', true);
error_reporting(E_ALL);
$url = 'http://address.com/".{{ category:country }}."/';
// Find a function which will parse the string you have passed into it
$url = FAKE_FUNCTION_templating_engine_PARSE_NOW($url);
// At this point, Simple HTML DOM will be able to properly use the $url
?>

但是在pyrocms中有一个内置的解析器：
以下是代码：
