Description:
------------
well, I expierenced today this error message (see the output field in
the bugreport)
But I checked it by running cmd.exe (the Windows NT standard shell) as
webserver user and I can simply access any files. The share is writable
and on a FAT32 partition so no chmods or so on apply.

Well some PHP details:
It seems that I can use any filesystem function in PHP to fail to access
it. (tested with file)
file_exists return false.
I am using PHP as apache module as distributed on www.php.net
Apache 1.3.28 with PHP 4.3.2
Something that maybe apply: Today I upgraded my Apache to 1.3.28 from
1.3.27.

Reproduce code:
---------------
<?php 
var_dump( file("\\\\somehost\\someshare\\somefile.txt") );

/* (line 8 is quoted in the bugreport) */
 ?>

Actual result:
--------------
Warning: file(\\pc4\hd2\do_chroot) [function.file.php]: failed to open
stream: Permission denied in c:\programme\apache
group\apache\htdocs\somescript.php on line 8

1. 4.3.3 is already released
2. And it's the permissions. Not bug.

well, I upgraded to 4.3.3 now.

But how to make sure that this is not a PHP bug? I am really sure that
it (the share and the files) is writable and readable.

or better: How to check that?

See bug #13292 (the last comment by christoph grottolo)
Should be documented somewhere..

Same problem on Win 98 SE, cli version
If running the script on a network redirected drive (e.g. net use x:
\\server\share)

1: <?php
2:
3: include './test2.php';
4:
5: ?>

This is OK on W2000, on W98SE php says:
Warning: main(.\test2.php): failed to open stream: Invalid argument in
test.php on line 4

Warning: main(): Failed opening '.\test2.php' for inclusion
(include_path='.;c:\php4\pear') in test.php on line 4

the only workaround I found is putting test2.php on a local drive, e.g.
c:\

But this imply ANY lan pc MUST have its own set of 'included' php
sources...

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.

Dup of bug #13292.
