Makes it tricky to move your PHP around *within* your document root
though. I try to make my code run equally well rooted in "/somedir/" as it
does in "/".

Putting everything in an 'includes' directory and then specifying the
location of the files in include_path allows you to easily move the
includes anywhere (including outside the document root altogether, which
is often desirable from a security POV) without making any changes to your
scripts at all.

Better to use "httpd.conf" or "php.ini" for such settings, but not
everyone is able to. I tend to use ".htaccess" for testing and then
migrate to "httpd.conf" once I'm sure.

As does "include_path" -- you just need to set it in php.ini.
