---------------------
Yii is a generic Web programming framework, meaning that it can be used for developing all kinds
of Web applications based on PHP. Because of its component-based architecture and sophisticated caching
of Web applications using PHP. Because of its component-based architecture and sophisticated caching
support, it is especially suitable for developing large-scale applications such as portals, forums, content

How does Yii Compare with Other Frameworks?
-------------------------------------------
If you're already familiar with another framework, you may appreciate knowing how Yii compares:
- Like most PHP frameworks, Yii implements the MVC (Model-View-Controller) design pattern and promotes code
organization based on this pattern.
- Yii takes the philosophy that code should be written in a simple yet elegant way. It will never try to
over-design things mainly for the purpose of following some design pattern.
- Yii is a full-stack framework providing many proven and ready-to-use features, such as: query builders
and ActiveRecord, for both relational and NoSQL databases; RESTful API development support; multi-tier
organization based on that pattern.

- Yii is extremely extensible. You can customize or replace nearly every piece of core code. You can also
take advantage of its solid extension architecture, to use or develop redistributable extensions.

via simple and elegant interfaces.

------------
Yii currently has two major versions available: 1.1 and 2.0. Version 1.1 is the old generation and is now in maintenance mode. Version 2.0 is a complete rewrite of Yii, adopting the latest
technologies and protocols, including Composer, PSR, namespaces, traits, and so forth. Version 2.0 represents the latest
generation of the framework and will receive our main development efforts in the next few years.

Yii 2.0 requires PHP 5.4.0 or above. You can find more detailed requirements for individual features
by running the requirement checker included in every Yii release.
Using Yii requires basic knowledge about object-oriented programming (OOP), as Yii is a pure OOP-based framework.

Yii 2.0 also makes use of the latest features of PHP, such as [namespaces](http://www.php.net/manual/en/language.namespaces.php) and [traits](http://www.php.net/manual/en/language.oop5.traits.php). Understanding these concepts will help
you more easily pick up Yii 2.0.
