XML 数据显示在源中而不是浏览器中

我正在使用以下代码来获取 XML，但是当我回显结果时，它在浏览器中不显示任何内容，但在源代码中显示它。

$enc = urlencode('SELECT vid, owner, title, description, thumbnail_link, embed_html, updated_time, created_time FROM video WHERE owner=****ID******');
$contents = file_get_contents("https://api.facebook.com/method/fql.query?query=$enc");

echo  $contents;

这是 PHP 页面我的测试页面

一旦我弄清楚了，我需要为 simpleXML 准备 $contents但我不确定我这样做是否正确？

$xml = <<<XML;
$xml .=$contents;
$xml .=XML;

echo $xml;

总结一下：

感谢您对问题 #1 的帮助，但我不完全清楚如何为 simpleXML 准备包含 XML 的变量。是否需要 << 和 XML;？

问题 #2 如何在 <<

I am using the following code to get XML but when I echo the result it shows nothing in the browser but shows it in the source.

$enc = urlencode('SELECT vid, owner, title, description, thumbnail_link, embed_html, updated_time, created_time FROM video WHERE owner=****ID******');
$contents = file_get_contents("https://api.facebook.com/method/fql.query?query=$enc");

echo  $contents;

HERE IS THE PHP PAGE My Test Page

Once I get that figured out I need to prep $contents for simpleXML but I am not sure if I am doing it right?

$xml = <<<XML;
$xml .=$contents;
$xml .=XML;

echo $xml;

So to sum it up:

Thanks for you help with Issue #1 butI am not completely clear how to prepare a variable that contains XML for simpleXML. is the <<<XML and the XML; required?

Issue #2 How to add wrap the variable in the <<<XML and XML; tags?
