Get HTML output (XML file with XSLT) with PHP

I have an XML file with a StyleSheet which is display data in HTML. So I want to get this data in my php code with just 2 files (1 XML and 1 PHP)

URL of my XML file : http://ift.tt/1rBwhJR

When I launch this url in my browser, it's display my XML data in HTML (output). I want to get this data with PHP to display the HTML code (XML data).

I've tried with file_get_contents('http://ift.tt/1rBwhJR'); but nothing is displayed.

Thanks by advance
