problem, the fix will show up soon at http://www.php.net/manual/.

up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.

This is back, on windows, realpath() returns still any path, even if it doesn't exist. (manual says it's supposed to return FALSE in such case)

I get the following output when run on Linux and Windows, both running 4.3.2.  I ran this test with the command line interface.  

<?php
    echo '['.realpath('./invalid/dir/or/file/name').']'; 
?>

The results:

On Windows : [d:\http\invalid\dir\or\file\name]
On Linux   : []

The function should return false if the file is not a valid file (according to the documentation).  It does not do this in Windows.  I am not making this up.  The problem still exists, on both Windows 2000 Pro and Windows XP Pro.  

Though possible, I doubt this is a configuration issue.
