NOTE: Tested with FastCGI module on IIS 7.
1. Verify you have info.php in your docroot.
2. Set the directive open_basedir="."
3. Request the script info.php

Reproduce code:
<?php phpinfo(): ?>

Expected result:
The phpinfo() output

Actual result:
PHP Warning:  Unknown: open_basedir restriction in effect. File(C:\inetpub\wwwroot\info.php) is not within the allowed path(s): (.) in Unknown on line 0

To verify the location that is not restricted you can do the following:
Add a virtual directory to the default web site with a physical path of the php-fastCGI.exe and put the info.php there as well.

Now you can see that when requesting the file from the virtual directory you will receive the phpinfo() output.

Do we really want to support relative path? It may (incidentally) have worked before but I can't think of any sane usage of a relative path for open_basedir.

We even document[1]:

| The special value . indicates that the working directory of the
| script will be used as the base-directory.

Well, '.' refers to the current working directory, and on startup,
that defaults to the location of the php-cgi executable, when run
as (F)CGI.  If you set open_basedir only at the request level
(i.e. from inside a PHP script), '.' works as advertized in the

Note that the php executable does not check the given script for
open_basedir violations at all.
