Ok, this snap seems to get everything except mounted volumes for me.
test output is now:
C:\mnt\test>php phptest.php
directory: bool(true)
junction.exe junction: bool(true)
mklink junction: bool(true)
mounted volume: bool(false)
I've found 3 ways to create volume junction points on Win 7: Through
the mountvol command, thourgh the mklink command, and though the
diskmgmt.msc GUI. They all result in the same behavior.
I also just found that mklink can create symlinks to volumes, which,
alas, also fail. (symlinks to directories & files work fine) 'dir'
command for symlinks vs. junctions to volumes looks like this:
2009.08.27 15.18 <SYMLINKD> test2
[\\?\Volume{c7981ed5-d602-11dd-ac24-806e6f6e6963}\]
2009.08.27 15.19 <JUNCTION> test3
[\\?\Volume{c7981ed5-d602-11dd-ac24-806e6f6e6963}\]
For the record, the following command sequence can be used to re-create
my test setup... c:\mnt & c:\mnt\test are regular directories.
C:\mnt\test>mkdir directory
C:\mnt\test>junction junction directory

Thanks for your work on this, unfortunately, my inability to keep track
of drive letters means I use a lot of mounted volumes...

And confirmed your last cases using Win7/Vista/2k8. In this case
junction are prepended with \??\. Fix applied, the next snap should
have it.

Automatic comment from SVN on behalf of pajoye
Revision: http://svn.php.net/viewvc/?view=revision&revision=287800
Log: - Fix for #48746, fix mounted volume and junctions when used from
vista or later, they are actually prepended with \??\

To do not miss a case again, can you please tell me how you create each
mounted volume or junction? If mnt is a mounted volume or not, etc.
Junction created with junction.exe works fine here on xp, 2k3, win7,
vista and 2k8, using normal parent directories (mounted volume or not).
For example (XP):
c:\mnt mounted volume (HDD)
c:\mnt\directory (mkdir directory)
c:\mnt\junction_abs (created with junction junction c:\mnt\directory)
c:\mnt\junction (created with junction junction directory from c:\mnt)
Using this script from c:\mnt\test (c:\mnt being a mounted volume):
<?php
var_dump(file_exists('directory'));
var_dump(file_exists('junction_abs'));
var_dump(file_exists('junction'));
C:\mnt\test>\php-sdk\snap_5_2\vc6\x86\php52\Debug\php.exe t.php
bool(true)
bool(true)
bool(true)
------------------------------------------------------------------------

"\??\" may be the cause (\\?\ is well documented not \??\). But I
wonder why junction.exe jucntion work just fine on our tests system (xp
and 2k3). Thanks for testing, I go back to code&test.
