自动加载类

我在包含文件夹中创建了一个名为 Database.class.php 的数据库类。这是我的代码：

require_once 'includes/smarty/Smarty.class.php';
require_once 'includes/admin.functions.php';

function __autoload($class) {
    require_once 'includes/'.$class.'.class.php';
}

try {
    $db = Database::getInstance(); 
} catch (PDOException $e) { die('Error connecting to database.'); }

这段代码有什么问题吗？前 2 个包含工作正常，我只收到“未找到类数据库”错误。

自动加载仅在创建新对象时才起作用吗？如果是这样，单身人士有解决方法吗？或者我做错了什么？

谢谢！

编辑：当手动包含时，它可以工作。所以这确实与自动加载有关..

I have created a Database class named Database.class.php in my includes folder. This is my code:

require_once 'includes/smarty/Smarty.class.php';
require_once 'includes/admin.functions.php';

function __autoload($class) {
    require_once 'includes/'.$class.'.class.php';
}

try {
    $db = Database::getInstance(); 
} catch (PDOException $e) { die('Error connecting to database.'); }

Is there anything wrong with this code? The first 2 includes works fine, I'm only getting a "class Database not found" error.

Does autoload only work when creating new object? If so, is there a workaround for singletons? Or am I doing something wrong?

Thanks!

EDIT:
When manually including, it works. So it's really related to the autoloading..
