Whether it is his own server or not is immaterial as it has no effect on
my statement.

And obviously you have not tried $_SERVER['DOCUMENT_ROOT'] = which also
allows you to keep your scripts in a file/folder structure. The
difference being dirname(__FILE__) changes depending on the calling
script's location = move the calling script and your code breaks.

For this reason it's a bad idea to use it to access other files unless
that file is *totally dependent* on the calling script and will *always*
be in the same relative location to the calling script. But such
assumptions also make the files more tightly coupled, creating
unnecessary dependencies.

$_SERVER['DOCUMENT_ROOT'] always points at the root directory of the
website and is independent of the calling script's location.
