Bug description:glob() returns false for a pattern that matches zero files

Description:
------------
On my system the glob() returns false if there are no files matching the
pattern even though the documentation
(http://php.net/manual/en/function.glob.php) states that it should return
an empty array. 

PHP version: 5.3.3

The only things I have changed in php.ini are open_basedir
(/srv/http/:/home/:/usr/share/webapps:/etc/webapps:/tmp/:/usr/share/pear/:/usr/share/symfony)
and enabling of several extensions (mcrypt, mysql, pdo, pdo_sqlite). 

I've seen similar bugs reported and closed a few years ago: #29928

Test script:
---------------
<?php 
    // phpMyAdmin is an empty, existing directory located in Apache root
    $glob = glob('/phpMyAdmin/*');
    echo $glob == false  ? "false\n" : ""; 
    echo is_array($glob) ? "array\n" : ""; 
?>                           

Expected result:
----------------
glob() should return an empty array if no files match the pattern.

Actual result:
--------------
The script prints 'false' when run on my box (both under Apache 2.2.17 and
with php from command line).
