CakePHP (http://book.cakephp.org/2.0/en/index.html) was initially built on ROR concepts. It follows a brilliant MVC pattern and gets you up and running with 'bake' (think 'rails generate') so if you know RoR and PHP, then you will feel very at home with Cake.
Yes, but their Model layer, in comparison with what ActiveRecord provides you with, is really not that great. One of the main aspects that I really didn't like was that the Model finder methods don't give you object instances back, but instead you get php arrays with the fetched data from the database.
