I'm a PHP dev who wants to escape. I'm trying to learn Ruby on Rails, but not doing well. I know functional Ruby and a fair bit of JavaScript.

The main barrier to my leaving PHP is that it basically forces me to use OOP. I want to use OOP, but I haven't got my head around it, and I'm yet to be persuaded that it's worth it and I don't really fully get the benefits.

Materials on learning Ruby and other languages tend to miss out that jump, which is the biggest one for me. Any ideas for getting me up to speed on OOP fully?
