[PHP] Strange is_dir() behavior

[Marcos Mendonça]

Hello

I'm using PHP 4.3.9, under Windows XP with Apache.

I have the following directory structure on a given app, i'm working on.

photos/
      > folder1
      > folder2
      > folder3
      > ... and so on

I'm trying the following code to make a list of folder under photos:

                      $d = dir('photos/');

                        while (false !== ($entry = $d->read())) {
                            if (is_dir($entry) && $entry != '.' && $entry != 
'..')
                                echo $entry . "<br />";
                        }

For some strange reason, that echoes nothing. is_dir is returning
false on every folder (dir)
under photos, except for '.' and '..' dirs. Can someone explain this?

Thanks ind advance.
Marcos
