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.

header ('Content-Type: text/plain; charset=utf-8');

is better.

To display an empty file?

I can do *that* by opening a new document in TextWrangler. But if I want 
to do something useful using SQLite, PHP, ajax, JavaScript, CSS, and 
HTML, I eventually figured out that using utf-8 throughout made my life 
a lot easier. Especially as I can convert any junk I receive *into* 
utf-8, using PHP tools.

Of course AGV is making fun of the charset for an empty file, but apart from that I
wish the use of utf-8 were generally accepted. I just don't understand why there is
still so much iso-8859 in use, this charset is so limited.

/Str.

Inertia and lack of awareness.

It may be your client which automatically creates this for "empty" 
documents. Did you verify this using wget or similar?

As you can see here - <http://arnowelzel.de/samples/empty.php> - this 
script does not produce any output.
