how about doctrine

about 1 year ago I got chance to do a project with Yii and I love it so much, but the past 10 month I was working with Symfony, and also amazing especially Doctrine it used. is it possible to use Doctrine in Yii?

Yes, it is possible. If I remember correctly, there were some wiki articles about it.

Out of curiosity: What do you gain by that? From what I can grasp, Doctrine is pretty similar to Yii’s query builder.
