Description:
------------
PHP's is_readable() and is_writable() function report nonsense on
ACLs...

We have the following test case:
A file containing 
<?php
echo __FILE__.' is '.(is_readable(__FILE__) ? '' : 'NOT
')."readable!<br>\n";
echo __FILE__.' is '.(is_writable(__FILE__) ? '' : 'NOT
')."writable!<br>\n";
?>

it's made accessible to the webserver via
$ getfacl index.php
# file: index.php
# owner: someuser
# group: webadm
user::rw-
user:apache:rw-
group::r--
mask::rw-
other::---

So apache is neither the owner nor in the group but it's accessible
through ACL.
If I call this file via the webserver, I get 
/srv/http/[...]/test/index.php is NOT readable!
/srv/http/[...]/test/index.php is NOT writable!

[...] has been inserted by me, of course.

This method works perfectly, the webserver (and also PHP) *can* read
and write the file but the is_readable() and is_writable() return wrong
values.

It really seems like bug #14923, but that one's fixed after php-4.1.0.
Also it's CLOSED, so I cannot add a comment there. :-(
