Operating system: Windows XP PRO SP3
PHP version:      5.2.6
PHP Bug Type:     Directory function related
Bug description:  is_dir returns incorrect result

Description:
------------
PHP function is_dir does not recognise some of the directories in my PC
directory structure.
Environment is:
. Dell Core 2 Duo PC
. Windows XP Pro SP3
. PHP version 5.2.6
. IIS version 5.1
. MySQL version 5.0.51b-community-nt
. Dreamweaver MX2004 version 7 as the "text editor"
. Internet Explorer version 6.0.2900
. sendmail.exe
All running on the Dell PC - i.e., all executions are via 'localhost'


Reproduce code:
---------------
$dir1 = "C:/AAImages/";
$dir2 = "C:/Documents and Settings/";
$dir3 = "C:/Documents and Settings/Fred & Ginger/";
$dir4 = "C:/Documents and Settings/Fred & Ginger/My Documents/";
$dir5 = "C:/Documents and Settings/Fred & Ginger/My Documents/AC Images
Test/";

var_dump (is_dir($dir1));  // returns true (correctly)
var_dump (is_dir($dir2));  // returns true (correctly)
var_dump (is_dir($dir3));  // returns true (correctly)
var_dump (is_dir($dir4));  // returns false (incorrectly)
var_dump (is_dir($dir5));  // returns false (incorrectly)

But all these directories do exist on my PC and I have checked the
spelling carefully. Permissions seem to be OK as I can upload files from
the lower level directories via an HTML form OK.


Expected result:
----------------
var_dump (is_dir($dir4)) and var_dump(is_dir($dir5)) should both return
TRUE, i.e., all of the 5 var_dumps should return TRUE.

Have tried it inversely and the same error is apparent - i.e., tried
var_dump(!is_dir($dir4)) etc.  With the 'not' tests I get false, false,
false, true and true.

Have also tried it with double backslashes in the directory names instead
of the single forward slashes - same error apparent.

Have also tried it without the trailing forward slash at the end of each
directory name with the same erroneous result.

Actual result:
--------------
var_dump (is_dir($dir1));  // returns true (correctly)
var_dump (is_dir($dir2));  // returns true (correctly)
var_dump (is_dir($dir3));  // returns true (correctly)
var_dump (is_dir($dir4));  // returns false (incorrectly)
var_dump (is_dir($dir5));  // returns false (incorrectly)

Any help/advice will be very much appreciated.
Thank you in anticipation.
