(I'll have a go at answering the actual question, rather than
posting about php.ini files which is a related, but separate,
topic).

Because PHP opens files relative to the currently running script's
location.  If you are running /usr/share/phpapp/myfile.php then
require_once('a.php') will require /usr/share/phpapp/a.php, regardless
of symlinks.

require_once($_SERVER["DOCUMENT_ROOT"] . "/config/phpapp.php");

(assuming your site's document root is set to /var/www/host.domain.tld/
for each site).
