Thank you for your reply first.

Yes I know I could set include_path either in the php.ini or at
runtime.But it's a little bit dirty I think.What I am confused about is
the fact that
require("./inc.php") can not work while require("inc.php"); works
correctly. How does php determine the include_path in this kind of
situation?

You can set the path(s) in php.ini

Edit the file and search on 'include'
