Description:
------------
In an attempt to glob() directory with bracket ('[' and/or ']') in its name, I get no results at all.

Reproduce code:
---------------
$dir = "./dir[with]brackets";

if (!is_dir($dir))
   mkdir($dir);

for ($i = 0; $i < 3; $i++)
   file_put_contents($dir."/file.".$i, "foo".$i."\n");

var_dump( glob($dir."/*") );

Expected result:
----------------
Array containing files in the said directory.

Actual result:
--------------
Empty array.
