Actually, that's the BEST WAY to reference your files.
$_SERVER['DOCUMENT_ROOT'] will ALWAYS contain the absolute path to the
root directory of your site, no matter where it is. You need to make no
changes to any files when referencing this way.
Then you don't need any entry in your .htaccess file (which even Apache
recommends against using), you don't have to worry about setting it up
or anything else. Everything works automatically.
I use this all the time in my sites. I can move them between different
test machines (both local and on the internet), the final site - whatever.
I've even moved complete sites from one provider to another. All that
was necessary was to upload and go.
And BTW - it works in IIS also, which doesn't have a .htaccess file.
Works great, in fact.
Use the server-provided values where you can. That's what they're there
for.
