Choosing a PHP Framework Round 2: Yii vs Kohana vs CodeIgniter
It was over a year ago that I wrote the article that compares CodeIgniter and Kohana. Since then both CodeIgniter and Kohana have seen major progress with the release of CodeIgniter 1.7.0 and Kohana 2.3.
In December 2008, a new PHP framework called Yii has been released to the public with a stable 1.0. There were a lot of new PHP framework released in 2008, but Yii was one of the more recognised ones because:
- The author, Qiang Xue, is the author of the well established PRADO framework.
- It is a simple to use, well organised, PHP 5 only MVC framework.
- It claims to have astonishing performance.
Before I start this round of comparison, let me briefly list my experience with these frameworks, so you may interpret this article with your own judgement.
CodeIgniter: I started using CodeIgniter since its version 1.2.x from a few years ago. During the past few years I have worked on projects mainly using version 1.5.x and 1.6.x. I have now stopped using CodeIgniter in favour of using other PHP 5 only frameworks.
Kohana: I first started using Kohana when it was called BlueFlame back when it was first forked out of CodeIgniter. Since then I have lurked and participated in the Kohana community. All of my recent projects are done in Kohana.
Yii: The 1.0 release of Yii had my attention, but I didn’t really dive into it until about now. However, most of my impressions on Yii are based on its documentation and this article by Daniel.
Let’s see how they compare with each other.
Same notes as before: Grading scale: Limited < Fair < Good < Excellent. If a feature is not available in the distributed package, but is available via 3rd party libraries, I will state that in the comparison. If a feature is available both in the distributed package and via 3rd party libraries, only the official one will get assessed.
