ABSTRACT

Yii is a high-performance component-based PHP framework for developing large-scale Web applications. It enables maximum reusability in Web programming and can significantly accelerate the development process. The name Yii (pronounced as Yee or [ji:]) stands for easy, efficient and extensible.

What is Yii Best for?

Yii is a generic Web programming framework that can be used for developing virtually all sorts of Web applications. Because it is light-weighted and equipped with sophisticated caching solutions, it is especially suitable for developing high-traffic applications, such as portals, forums, content management systems (CMS), e-commerce systems, etc.

How is Yii Compared with Other Frameworks?

Like most PHP frameworks, Yii is an MVC framework. Yii excels over other PHP frameworks in that it is efficient, feature-rich and clearly- documented. Yii is carefully designed from the beginning to fit for serious Web application development. It is neither a byproduct of some pro ject nor a conglomerate of third-party work. It is the result of the authors’ rich experience of Web application development and the investigation and reflection of the most popular Web programming frameworks and applications.

1.2 What is Yii

Yii is a high-performance component-based PHP framework for developing large-scale Webapplications. It enables maximum reusability in Web programming and can significantly

accelerate the development process. The name Yii (pronounced as Yee or [ji:]) standsfor easy, efficient and extensible.

Requirements

To run an Yii-powered Web application, you need a Web server supporting PHP 5.1.0 or higher.

For developers who want to use Yii, understanding ob ject-oriented programming (OOP)is very helpful, because Yii is a pure OOP framework.

1.3 What is Yii Best for?

Yii is a generic Web programming framework that can be used for developing virtually all sorts of Web applications. Because it is light-weighted and equipped with sophisticated

caching solutions, it is especially suitable for developing high-traffic applications, such as

portals, forums, content management systems (CMS), e-commerce systems, etc.

1.4 How is Yii Compared with Other Frameworks?

Like most PHP frameworks, Yii is an MVC framework. Yii excels over other PHP frameworks in that it is efficient, feature-rich and clearly-documented. Yii is carefully designed from the beginning to fit for serious Web application development. It is neither a byproduct of some pro ject nor a conglomerate of third-partywork. It is the result of the authors’ rich experience of Web application development and the investigation and reflection of the most popular Web programming frameworks and applications.

1.4 Installation

Installation of Yii mainly involves the following two steps:

  • Download Yii Framework from yiiframework.com.
  • Unpack the Yii release file to a Web-accessible directory.

Requirements

After installing Yii, you may want to verify that your server satisfies all the requirementsof using Yii. You can do so by accessing the requirement checker script at the followingURL in a Web browser:

http://hostname/path/to/yii/requirements/index.php

The minimum requirement by Yii is that your Web server supports PHP 5.1.0 or above.

Yii has been tested with Apache HTTP server on Windows and Linux operating systems.

It may also run on other Web servers and platforms provided PHP 5 is supported.
