Description:
------------
say you have the folder "test" and inside "test" you have:
- images (folder)
- the_following_code.php (file)

inside the "images" folder you have some sub directories. the_following_code will NEVER return true.

if i use !is_dir instead, it then returns the sub directories as files instead of folders. this appears to have been an ongoing problem, perhaps overlooked or under-explained.

Reproduce code:
---------------
function directory($dir)
{
    $mydir = opendir($dir);
    while(false !== ($file = readdir($mydir)))
    {
        if($file != "." && $file != "..")
        {
            if(is_dir($file))
                echo "$file<br>\r\n";
            elseif(is_dir($mydir.$file))
                echo "$file<br>\r\n";
            elseif(is_dir($mydir.$file.'/'))
                echo "$file<br>\r\n";
        }
    }
    closedir($mydir);
}
$path = '/inetpub/wwwroot/Scripts/test/images/';
directory($path);

Expected result:
----------------
i expect a list of sub dirs..

Actual result:
--------------
i get nothing.
