Multiupload file script php

[boots]

Non vorrei sbagliarmi, ma dovresti fare qualcosa del genere:

Send this file: <input name="userfile[]" type="file" multiple="multiple" /> 

$uploaddir = "uploads/$id/";
foreach($_FILES['userfile'] as $file){
     $uploadfile = $uploaddir . basename($file['name']);
     if (move_uploaded_file($file['tmp_name'], $uploadfile)) {
        $c = 1;  // ???
     } else {
        $c = 1;  // ???
     }
} 

RETTIFICO

$_FILES ha una struttura particolare, bisogna cambiare il ciclo così:

$files = $_FILES['userfile'];
for($i=0;$i<count($files['name']);++$i){
    $uploadfile = $uploaddir . basename($files['name'][$i]);    
    if (move_uploaded_file($files['tmp_name'][$i], $uploadfile)) {
        $c = 1;  // ???
     } else {
        $c = 1;  // ???
     }
}
