Hi Webmaster,

This code is called the XML Declaration (defined in the XML
Recommendation [1]):

   <?xml version="1.0" encoding="UTF-8"?>

It is not PHP code and is likely to produce an error if fed to
a PHP processor as is. 

In the example you site below, it is the first part of
an XHTML document [2]; XHTML is an XML vocabulary. 

Perhaps someone has configured a Web server incorrectly and is
serving this content with a media type that suggests it is PHP.
For information about Internet media types for xhtml, please consult
[3].

I hope that helps,

 _ Ian
