High Scores module

This is a Zend AMF endpoint I created to receive postback from a client's existing Flash game and convert the received info into an account-associated Drupal node. The nodes were then used to provide all-time and personal score info to users of the Drupal-based website.

highscore.php:

<?php

error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 'on');

require 'Zend/Amf/Server.php';
require 'highscore.class.php';

$server = new Zend_Amf_Server();
$server->setClass('highscore');

echo $server->handle();

highscore.class.php:

<?php

class highscore
{
    // Constructor stubs so AMF Server doesn't get angry
    public function __construct() {}
    public function highscore() {}

    // Individual values method
    public function submit(
        $user_id = null,
        $song_id = null,
        $difficulty = null,
        $score = null,
        $start_time = null,
        $end_time = null
    ) {

        // Make sure we got everything we needed from the postback
        if (
            !is_null($user_id) &&
            !is_null($song_id) &&
