Scanning directories in my Network via PHP

I want to read all the directories from a directory specified via PHP. (unfortunatelynot good enough in VB / C / Java to create a more efficient solution)

With this code, I can read all files from / tmp / example using a Mac:

<?php
$config = array(


    'dir' => '/Volumes/Data/Media-Server/Musik/Sortiert', // path to scan
    'depth' => 2, // depth of scan
    'html' => true // html output (bool)


);


if(file_exists($config['dir'])) {


    if(is_readable($config['dir'])) {


        $array = scandir($config['dir']);
        print_r($array);


    }


}
?>

Good luck....................!!!!!!!!
