Very good. You are right. Across samba it works fine, so the issue
appears to be
in VirtualBoxes implementation.
Thanks!

Remote shares work just fine, including is_readable.
I have no idea what uses virtualbox for the shares, I suppose some
custom versions of Samba.
But it does not look like a PHP problem to me, as shares work fine in
our test platforms (with Samba too).
I would suggest to debug virtualbox to see what it does or what is used
for the share and then try to figure out why it fails.

remove was meant to be remote. (of course)

The two scripts (identical except for the driver letters) are only to
make it
explicit that one result is on C: - the local drive, which you asked
about - the
answer is there, and the other N: - the remove drive.
Does it work with local filesystem as expected? - Yes - that is what C:
is
showing.
What is used on the remote host? Samba? Which version? - VirtualBox does
the
sharing. Not the remote host.
Please show one script and what you expect as output or result. - It is
the same
script aside from the drive letters which just make it more explicit
what is
happening.

Why expected and actual results show two different scripts?
Please show one script and what you expect as output or result.
Btw, the OS is about where PHP runs, not what you use on some remote
servers :)

Description:
------------
This is the setup I have.
Windows guest in a VirtualBox with a network drive connected to a
network share
on the virtual machine to an ext3 directory on the Linux host.
In other words in Windows N: is connected to \\vboxsvr\nev which is the
directory
/home/nev on the Linux box.
Php is_readable($file) where $file is a filename on the N: drive returns
false
though the file is readable.
Test script:
---------------
<?php
assert(!is_readable('N:\test.txt'));
echo file_get_contents('N:\test.txt');
?>
Expected result:
----------------
If the test is on C:\ it works correctly. The assertion fails.
C:\test.txt contains the text 'this is a test'.
<?php
assert(!is_readable('C:\test.txt'));
echo file_get_contents('C:\test.txt');
?>
C:\>php test.php
PHP Warning: assert(): Assertion failed in C:\test.php on line 2
Warning: assert(): Assertion failed in C:\test.php on line 2
this is a test
C:\>
Actual result:
--------------
N:\test.txt contains the text 'this is a test'.
<?php
assert(!is_readable('N:\test.txt'));
echo file_get_contents('N:\test.txt');
?>
Gives this result...
N:\>php test.php
this is a test
N:\>
