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.
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.
