Changing version from 5.2.5 to 5.3.0beta1 to facilitate this getting
fixed before the next release.

This problem still exists in 5.3.0 beta 1
(http://windows.php.net/downloads/qa/php-5.3.0beta1-Win32-VC6-x86.zip)

Fixed in CVS HEAD and PHP_5_3.

Doh, sorry, thought I could edit the original text. Just delete that
comment.

But yes, as Daniel correctly points out, it's all Windows permission
handling (As my reproduce code also shows), not just related to network
shares... I experienced it in one at first, I guess that's why it stuck
in my brain.

Description:
------------
If the parent directory of a Windows directory is not accessible,
you are still able to access subdirectories if given explicit
permission.

However, PHP has trouble with the first accessible directory below an
inaccessible directory. This is not a problem for the accessible dir's

subdirs, though.

Scenario:
C:/Test/NoAccess/  -- Not accessible
   Access/        -- Accesible from here
      yyyyyyy.txt
      Subdir/
         xxxxxxx.txt

The problem has been found with opendir(), is_dir() and is_readable().
All directory functions are probably affected.

No workarounds has been found so far (suggestions appreciated).

Reproduce code:
---------------
<?php
if ($handle = opendir("C:/Test/NoAccess/Access/Subdir")) {
	echo "Opened dir C:/Test/NoAccess/Access/Subdir<br/>";
	while (false !== ($file = readdir($handle)))
		echo"File: $file<br/>";
	closedir($handle);
} else {
	echo "Hmmmm, can't open directory, is it accessible?<br/>";
}
echo "<br/>";
if ($handle = opendir("C:/Test/NoAccess/Access")) {
	echo "Opened directory C:/Test/NoAccess/Access<br/>";
	while (false !== ($file = readdir($handle)))
		echo"File: $file<br/>";
	closedir($handle);
} else {
	echo "Hmmmm, can't open directory, is it accessible?<br/>";
}
?>

Expected result:
----------------
Opened dir C:/Test/NoAccess/Access/Subdir
File: .
File: ..
File: xxxxxxx.txt

Opened dir C:/Test/NoAccess/Access
File: .
File: ..
File: yyyyyyy.txt
File: Subdir

Actual result:
--------------
Opened dir C:/Test/NoAccess/Access/Subdir
File: .
File: ..
File: xxxxxxx.txt

Warning: opendir(C:/Test/NoAccess/Access) [function.opendir]: failed to
open dir: No such file or directory in
C:\Inetpub\wwwroot\pm2\opendir.php on line 13
Hmmmm, can't open directory, is it accessible?

I am experiencing this issue as well, but on local directories, not
network shares.  My OS is Windows XP Pro.  The opendir() functionality
works correctly in release 5.2.1.  The functionality is broken in
releases 5.2.2 through 5.2.5, plus the 526-php5.2-win32-200802292130 and
php5.3-win32-200802201330 snapshots.
