php - garbled xml output

Question

I'm trying to parse an xml feed using PHP: http://trustbox.trustpilot.com/r/travelnation.co.uk.xml

Visiting this, it looks perfectly OK, but when I try

<?php
$file = file_get_contents("http://trustbox.trustpilot.com/r/netamity.com.xml");
print_r($file);
?>

I get

‹•SÁŽÓ0=/ÿ`ŒÄmœ-  븊àèJV«••L«ŽmÙN²ý{Æi·M
...

How is it getting garbled? Using simplexml it wont parse it (unsurprisingly). I've tried setting headers UTF-8 headers but I think the issue is in the get_file_contents. Any ideas?

内容看起来很“奇怪”，仅仅是因为编码被压缩（参见 HTTP 标头Content-Encoding: gzip）。

HTTP/1.1 200 OK

我想您需要知道如何通过 HTTP 读取文件；你可以在 SO 上试试这个。
