On NetTuts.com today there's a new tutorial posted about using a microframework for prototyping an application you may not need a full stack framework to get running. Their examples are based on the Slim framework.

Let’s face it: we all have great ideas for a web application. Whether you write them down on paper or remember them using your eidetic memory, there comes a point when you want test whether or not your idea is really viable. In this tutorial, we’ll use a micro framework, a templating language and an ORM to rapidly develop an application prototype.

There's an introduction to help you get Slim, some extras, Twig templating and Paris and Idorm set up and working happily together. There's code included for bootstrapping the application, creating a few routes, building models and using them to pull data from the database. They also create an "admin" area for their sample blog application, building an "add article" form and protecting it with a simple login system. You can download the source if you'd like to see it all working together.
