[PHP-WIN] Absolute and Relative directory

[Michael Bao]

Hello everyone,

When I included some file, I must key in the absolute directory, as following:

require ("d:/iis/www3/lib/common/auth.inc"); 

but I need relative directory, like require ("/lib/common/auth.inc"); 

So I change include_path line to "include_path = d:/iis/www3/" in "php.ini" file. But 
it doesn't work.Please tell me the reason.

thank you,

Michael Bao
