listing the FOLDERS in a directory

[forcer]

is it possible to list the folders in a directory but not the files?

<?php
$dir = "/tmp/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if(is_dir($file)) echo "directory: $file <br>";  // only display if it's a folder
        }
    closedir($dh);
    }
}
?>
