History

The Yii project started on January 1, 2008, in order to fix some drawbacks of the PRADO framework. For example, PRADO was slow when handling complex pages, had a steep learning curve and many controls were difficult to customize, while Yii is much easier and more efficient.[2] In October 2008 after ten months of private development, the first alpha version of Yii was released. On December 3, 2008, Yii 1.0 was formally released.[1]

Extensions

The Yii project has an extension repository consisting of user-contributed components.

There was also an official extension library whose name was zii, which was then merged with core framework. It is bundled in every release since Yii version 1.1.0 and it includes additional behaviors and widgets, such as grids and jQuery UI widgets.

Documentation

Yii comes with a collection of official documentation, such as a tutorial to develop a simple blog application, a guide that gives the description of every feature and a class reference which gives every detail about properties, methods and events.

There's also a user-contributed documentation, most of which is available within the wiki on the official website.

Yii is released under the New BSD License (3-clause license). This means that it's possible to use it for free to develop either open-source or proprietary Web applications.[1]
