autoloadincludephp

调用其他类的方法
假设一个php文件一个类，那要继承其他类，就必须先include这个php文件，但我看一些框架没有写include就能直接对其他类实例化对象，这是怎么做到的？
我只知道有个__autoload，还有其他的吗？都是怎么运作的？
还是隐藏了include？怎么隐藏的？

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
