Why is the thinkphp add composer automatic loading invalid?

I'm here ThinkPHPOf index.phpAdd the following:

// 添加第三方库自动加载require './vendor/autoload.php';

However, when using the prompt 类不存在 .

But in Controller addition require , it can be used.

What is the cause of it? Is there only one class loader? Thinkphp also wrote a, resulting in a class loader that covered the composer?

Do you have any idea? Thank you.

I see this question inside, there is a answer, said is in the English document inside.

Spl_autoload_register can handle situations where multiple loaders are required, in which case Spl_autoload_register will sequentially invoke the previously registered loader. As a comparison, __autoload can only be defined once because it is a function.

There should be more than one.

5.0版本支持Composer安装的类库的自动加载，你可以直接按照Composer依赖库中的命名空间直接调用。

Poof, I know what caused the ... Before, require ThinkPHP.php after the introduction, in fact, at the require './ThinkPHP/ThinkPHP.php'; time, it has started in 执行ThinkPHP the core code, has been routed into the Controller inside of the ...
