[PHP-BUG] Bug #51506 [NEW]: Realpath failed on linux Server for version 5.2.10 ?

From:             
Operating system: Linux
PHP version:      5.2.13
Package:          Apache2 related
Bug Type:         Bug
Bug description:Realpath failed on linux Server for version 5.2.10 ?

Description:
------------
hi,

I met an issue using a drupal CMS. I received an error "warning:
move_uploaded_file() [function.move-uploaded-file]: Unable to access in
/home/.sites/38/site52/web/includes/file.inc on line 572."

I have several web environement, one for coding the website (with IIS 6 and
PHP 5.2.3), on for production (with Linux, Apache 2.0 and PHP 5.2.10).

I have no issue on my development server with IIS (same files, same
database).

when I run the following line of code :

var_dump( realpath( dirname( __FILE__ ) ) );

Under IIS: string(44) "D:\inetpub\vhosts\dev.*******.com\httpdocs" 

Under Apache: bool(false)

Did I miss something ? 


Best regards,

Denis.

Test script:
---------------
var_dump( realpath( dirname( __FILE__ ) ) );

Expected result:
----------------
I wish that this function gives me the real path to let drupal copy some
files from the administration.
