leggere directory + cancellazione e modifica file

[torrone]

salve

allora prendendo spunto da una bella pillola

<?
function dirtree($path){
/**
* author: kuarl<grivier@animeterminal.it>
* date: 26-08-2002
*/
    $fd = opendir($path);
    while($file = readdir($fd)){
        if($file != '.' && $file != '..'){
            $ris[count($ris)]['name'] = $path."/".$file;
            $ris[count($ris)-1]['size'] = filesize($path."/".$file);
            $ris[count($ris)-1]['last_mod'] = filemtime($path."/".$file);
            $ris[count($ris)-1]['last_acc'] = fileatime($path."/".$file);
            $ris[count($ris)-1]['perms'] = fileperms($path."/".$file);
            $ris[count($ris)-1]['type'] = filetype($path."/".$file);
            if(is_dir($ris[count($ris)-1]['name'])){
                //unset($ris[count($ris)-1]); // commentandola avrete anche i nomi delle directory
                $ris = array_merge($ris, dirtree($path."/".$file));
            }                
        }
    }
    closedir($fd);
    return $ris;
}
$dir = dirtree('H:/Image Gallery');
foreach ($dir as $super => $valore)
    foreach ($valore as $chiave => $value)
        print "[$super][$chiave] > $value
\n";
?>

attaccandomi a questa, come faccio a poter cancellare e modificare i file??

grazie!!
