The November 5th meet up is going to be presented by Rob Allen (@akrabat).

Slim is a PHP micro framework that enables you to write powerful web applications and APIs

In this talk, Rob Allen will give an overview of version 3 of framework and show how you can easily write maintainable applications with it. We will look at how Slim's middleware system leverages the PSR-7 HTTP request and response definitions to create easily understandable and flexible applications. We will also cover application setup, routing and the relationship between actions and middleware.
