The development of Yii framework began on January 1, 2008. It is an open source application that supports object oriented programming. It is also a component based MVC (Model-View-Controller) web application framework. The purpose for its development was to fix the drawbacks of a then widely used PRADO framework.PRADO was incapable of delivering a fast performance when it came to handling complex pages. Moreover PRADO was also difficult to customize. This is where development by Yii framework comes in handy. Yii even has a provision to store user-contributed components in its extension repository.The development stage took 10 months and finally it on October 2008 that an alpha version of Yii was released. But it was on December 3, 2008 that the full version was formally introduced in the market.Why Yii is Good for You?1. Easy to Install
For every web developer time is of the essence. Therefore it is important that while handling a framework the installation time must be greatly reduced.
Too much time spent on installation will lead to loss of money.
Moreover it will cost the developers valuable time that they require to implement for the process of web development.
This is because of an uncomplicated, easy installation and configuration process that comes with Yii.
2. Modern Technologies

This includes the latest static binding, SPL classes and interfaces and anonymous functions.
3. Highly Extensible

5. Simplified Security
Proper security is essential for any web application and this is where Yii can help you.
Yii has a security application component that exposes several methods to help assist in creating a more secure application.
6. Shorter Development Time
Repetition tasks are unwelcomed as most developers consider them to be waste of time. But the fact that things can’t be done without taking care of them, makes them important.
This is where Yii helps you to spend less time on these tasks and more time customizing your application to suit your needs.
