Summary
In this chapter, we were introduced at a very high level to the Yii PHP web application framework. We also covered a number of software design concepts embraced by Yii. Don't worry if the abstract nature of this initial discussion was a tad lost on you. It will all make sense once we dive into specific examples. But, to recap, we specifically covered:
The importance and utility of application development frameworks.
What Yii is and the characteristics of Yii that make it incredibly powerful and useful.
The MVC application architecture and the implementation of this architecture in Yii.
A typical Yii web request lifecycle and URL structures.
Object-relational mapping and Active Record in Yii.
