Ryan from Scarletlullaby.com has posted a new item today looking at the process he followed to refactor a Rails MVC application into PHP.
Most of my work of late has involved refactoring and rewriting insanely large and out of control programs so that it's easier to add features, follow program flow, etc. Since I've been using Rails so much in my personal projects, I tend to refactor things in a way that makes them resemble Rails in a funny, PHP-molested way.
I've come up with fairly decent and clean ways to implement most of the functionality available in Rails; basically, the PHP apps are set up using a frontcontroller, which delegates to instances of page controllers.
He looks at some of the "strange thoughts" he's had in the process, including issues dealing with POST/GET values, session data, and difficulty surrounding the fact that PHP dosen't support multiple inheritance.
