Summary
You've learned about the basic classes and uses of the PHPLib in this chapter. You've seen that it's a powerful solution for many problems you'll inevitably face when creating Web applications—yet it's easy to use once the necessary framework has been established. It provides a complete infrastructure for session management and user authentication in all aspects.
In the next chapter, you'll see the PHPLib in use with a real-life application. That chapter also shows another class of the PHPLib that we haven't mentioned yet: the Template class for separating code from layout.
