Apparently, you are inspecting the output through a web browser and your 
browser has reached the conclusion that you are loading an HTML 
document. Since your (empty) code is not valid HTML, the browser does 
what it's been designed to do: fix it. In this case, it adds a few tags 
to obtain a valid empty HTML document.

The PHP way to make sure your output is not handled as HTML is to send 
an appropriate HTTP header, e.g.:

header('Content-Type: text/plain');

Additionally, you can remove the trailing "?>" closing tag, which is not 
mandatory and might lead to white space being sent to the browser.

The use of uppercase tags and Win-1252 encoding suggests we are talking 
about Internet Explorer. This browser is known for ignoring the 
Content-Type under certain circumstances. But of course that's another 
story.
