which framework would be best to migrate an existing donation processing php website to a php framework ?? please provide some justifications for your answer ..
Three frameworks are in my mind : CakePHP, CodeIgniter, Yii
Cakephp and yii have PDO implemented. I'll use YII, i love the way it implements the stuffs. Generate migration using command line.. crud using web interface (so easy). You can add foreign keys on your migration.. his support to database is larger than the cake php. The model methods and pdo are so easy to work with, it have a lot of examples.
Cake php is sweet too, but Yii have more things and is more advanced. The default scaffold on yii is better, advanced search implemented and jquery on the fly
