简单的PHP名称空间问题

Question

Trying to implement a 3rd-party-lib with PHP 5.3.9-ZS5.6.0 and the lib uses namespaces. The code where I want to use the lib doesn't. So i have:

• facebook.php
• Mute

(Mute is the folder of the lib)

In facebook.php I try:

$app = new \Mute\Facebook\App();

Resulting in: Fatal error: Class 'Mute\Facebook\App' not found in...

The files are all in place. I can say:

use \Mute\Facebook\App;

without getting any error/warning... What am I missing?

When I require the "App.php" via require_once I get the next error: Fatal error: Interface 'Mute\Facebook\Bases\AccessToken' not found in [...]/Mute/Facebook/App.php

Mute/Facebook/App.php:

<?php
namespace Mute\Facebook;

use Closure;
use Exception;
use Mute\Facebook\Bases\AccessToken;
use Mute\Facebook\Bases\Batchable;
use Mute\Facebook\Bases\Configurable;
use Mute\Facebook\Bases\Requestable;
use Mute\Facebook\Bases\RequestHandler;
use Mute\Facebook\Exception\CurlException;
use Mute\Facebook\Exception\GraphAPIException;
use Mute\Facebook\Exception\HTTPException;
use Mute\Facebook\Exception\InvalidArgumentException;
use Mute\Facebook\Exception\OAuthSignatureException;
use Mute\Facebook\Util;

class App implements AccessToken, Batchable, Configurable, Requestable, RequestHandler
{ [...]

Answer 1

function __autoload($class_name) {
    require_once str_replace('\\', '/', $class_name) . '.php';
}

I created a __autoload function to "magically" require all files I need. Totally forgot about this method >.<
