If you loop through them as an array, it’ll work just the same:

foreach($_FILES['file'] AS $key=>$file) {
    $filename = $file['tmp_name'];
    $size = $file['size'];
    $newfile = $_SERVER['DOCUMENT_ROOT'] . "/uploads/" . date("Ymd_his") . "_" . $filename;
    move_uploaded_file($filename, $newfile);
}

And it’ll loop through each upload and process as such.
Just be sure that you have something that changes between each (I added a timestamp) – otherwise you’ll only end up with one file.

You were right with the inputs as

<input type="file" name="file[]" />

You can have as many of those as you’d like
