One cause of the spaghetti code was the mixing of business logic and of presentation. The separation of concern was easier in smarter languages (like ruby or scala) than in php. Nowadays, templating and presentation is mostly performed on the client side and the server handles only the business. As a result, there is less difference between ruby and php. Nevertheless, the event style of javascript (scala ?) provides better performances.
