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.
