'mnt' is a regular directory. 'junction' was indeed pointing to the
root of a volume. However, I get exactly the same behavior if I create
the junction as a link to anouther directory via the junction.exe from
sysinternals. Again, this is a log from Windows 7 x64:



C:\mnt\test>type phptest.php
<?php
var_dump(file_exists('junction'));
var_dump(file_exists('directory'));
?>
C:\mnt\test>dir
 Volume in drive C is coreI7_System
 Volume Serial Number is 38E2-2B62

 Directory of C:\mnt\test

2009.08.10  16.11    <DIR>          .
2009.08.10  16.11    <DIR>          ..
2009.08.11  08.22    <DIR>          directory
2009.08.10  16.10    <JUNCTION>     junction
[\??\C:\mnt\test\directory]
2009.08.10  16.11                82 phptest.php
               1 File(s)             82 bytes
               4 Dir(s)  24,210,726,912 bytes free

C:\mnt\test>php.exe phptest.php
bool(false)
bool(true)

Did you mount another drive in c:\mnt?

Sorry but I can't reproduce it on vista/win7/2k8 but only on 2k3 and
xp.

How exactly did you create the junctions on these platforms? It looks
like you create a junction to the root of another drive, right?

For what it's worth, I've reproduced the incorrect behavior on the
following OSes so far:
Windows 7 x64
Vista x64 SP2
Server 2003 x64 SP2
XP SP2

and confirmed using XP SP3 as well.

For the record, get the junction command here:

Ok, seems to be 2k3 specific. The same setup works on 2k8/vista/win7.
Thanks for your feedback!
