Description:
------------
Executing a code bellow for a file/directory with extended permissions (ACL) 
return wrong results.
E.g. a file with these ACLs (display permissions using OS getfacl command):

# file: file
# owner: user
# group: apache
user::rwx
group::r-x
group:webmasters:rwx
group:users:rwx
mask::rwx
other::---

The PHP code however returns 0757, which is weird (other has no permissions at 
all, but according fileperms it has rwx).

When I clear any extended permissions, the PHP code returns expected result of 
0750.

Test script:
---------------
<?php

echo substr(decoct( fileperms("file") ) , 2);

?>
