PHP Framework Yii – Good for Web 2.0 Development

Choosing the best framework for your project is quite difficult as there are tons of frameworks available. Every framework has its advantages, disadvantages, and features. Making projects without a framework is a very tough job. Frameworks make your work much easier and give you some additional features and security.

So in this article, we are going to cover the basic overview of Yii framework development which can help you select a framework for your next project.

What is Yii?

The name Yii is an acronym for “Yes It Is”. For your every question the answer will be yes it is. It enables maximum reusability. Yii is a high performance and component-based framework. It is a free and open source. It is a pure OOP framework. It works on MVC (model-view-controller) structure. To run Yii2 you need a web server that supports PHP 5.4.0.

At very first Qiang Xue (founder of Yii and PRADO) started to attempt to fix drawbacks of PRADO (“PHP Rapid Application Development Object-oriented”): slow handling of complex pages and difficulty to customize many controls on 1st January 2008.

In October 2006 after 10 months of development, the first version of Yii was released followed by 1.00 in December 2008.

In January 2010, Yii 1.1 was released adding form builder, unit testing and more.

In May 2011 developers decided to use new PHP versions and fix architectural issues. Version 2.0 was made in the same month.

In May 2013 the Yii 2.0 code went public, followed by the first stable release of Yii 2.0 in October 2014. The current version 2.0.7 also supports PHP7.

Why Yii?

There are many features of Yii so it is used mainly there are the following features:

  • Yii provides in-built validations facility.
  • Yii provides an extension called GII which makes your work easier by generating models, controllers, and views.
  • It also generates CRUD using GII and provides inbuilt authentication.

You can find Yii source code from the repository:

Yii is so fast because it does not include class until it is used for the first time and it does not create an object until it is accessed for the first time. Yii is secure because it handles 3 major types of attacks explain below:

XSS (cross-site scripting)

In poorly made form the user can enter malicious JavaScript in the form and it will appear on the page but in Yii, it checks for all malicious code entered and blocks those codes from entering to a website. This justification is done by CHtmlPurifier in Yii.

CSRF (cross-site request forgery)

This type of attacks can result in money loss. Yii uses $_GET request to retrieve data only not to modify anything so this doesn’t result in money loss.

Cookie attacks

Yii has cookie validation methods which block cookies from modified by harmful persons. And for this reason, people chose Yii for Business.

Some other features

You can make a relation between tables by a single line of code. It supports AJAX and jQuery so that we can avoid reloading a particular page. It uses caching which reduces the loading time. It provides error handling. It has great error handling methods which handle all warnings.

Yii is professional because it is based on MVC which clearly separates logic and presentation. It allows developers to formulate reusable code.


Yii framework is a great choice if you are developing a website with structured design Yii makes it easy by MVC. Your website speed will also fast as Yii is high performance. And it provides full security. And if you are good in OOPs concept then you can learn Yii very fast.
