Wrong. PHP doesn't care that much about these paths themselves, both ASP
and PHP need the path to give it to the filesystem and to retrieve the
file pointer. Which means, on the same system both PHP and ASP would
behave the same way to get the same files from the same locations.
Difference stays in the fact that you can also configure it in the
php.ini file. For instance, if you add '.' in php.ini then every file
request will be relative to your current location (check it, it might
not be set for you - include_path directive).

dot `.' is the current directory *relative* to the current directory -
makes not much sense in many cases.

a cute way to accomplish the above is:
define('CORE_PATH', dirname(__FILE__) . '/');
