php脚本强制下载xml文件

Question

I have the following PHP code:

<?php
header("Content-Type: application/force-download; name=\"test.gpx");
header("Content-type: text/xml"); 
header("Content-Transfer-Encoding: binary");
header("Content-Disposition: attachment; filename=\"test.gpx");
header("Expires: 0");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
echo (readfile("test.gpx"));
?>

The PHP code forces the browser to download a .gpx file. The mime type is text/xml. The file is always named test.gpx and the file is always in the same folder as the php file. The code works fine except that it adds the following lines to the end of the file that is downloaded.

<!-- Hosting24 Analytics Code -->
<script type="text/javascript" src="http://stats.hosting24.com/count.php"></script>
<!-- End Of Analytics Code -->"

What is causing the extra lines of text to be added and how can I prevent that. Thanks for any help you can offer.

Answer 1

This is a hosting24 issue. It adds analytics code to (nearly) all files. You could try to "trick it" by changing the Content-Type to "application/xml", which off course isn't entirely correct, but could avoid the analytics add.
