• Automatic loading of __autolaod and Spl_autoload_register ()

  Automatic loading means that if you can't find a way to handle a class, see this article, which can be said that Spl_autoload_register is a more advanced, more flexible way to load.

• Name space

  In C + +, namespaces were introduced early to resolve naming conflicts, and as PHP's engineering volume increased, the namespace mechanism was introduced in php5.3. With auto-loading and namespaces, the popular composer Package manager for the PHP community is now available on this basis. I have to say that composer is a very good package manager, much better than Nodejs's NPM, and Python's PIP. Refer to this article for a namespace.
