AAARGH! This question comes up practically every week!

This is an absolute *HTTP* URL, not an absolute *filesystem* URL. So it
obtains filename.php by performing an HTTP request to the specified
server, which just happens to be "localhost" in this case.

And of course, a server set up to parse and execute PHP files will parse
and execute filename.php when it's requested, so all your include() call
sees is the output result of filename.php.
