It's been three years I use Yii after trying several php frameworks.
FuelPHP is awesome!!!!
Codeigniter best framework, before I was trying cakePHP but it was too tricky to develop with..
Simply the best
What can I say? its the best!
Yii is great well architected and we can easily integrate third party php codes like ZF components
Très rapide et beaucoup plus facile à apprendre que Zend, et Symfony
