Silex - The Symfony2 microframework View session page
English session - Introduction
This talk will bring you closer to the Symfony2 based Silex microframework, explain use cases, go into internals, such as the Pimple service container, and show you how to use it. After this talk you will know more about Symfony components, PHP 5.3 closures, functional testing, and get a taste of simplicity, minimalism and perfectionism combined.
English session - Introduction
Pushing data from the server to the client as events happen has not really been possible in the web so far. While there have been some workarounds for this issue, most commonly referred to as "Comet", most of these were hacks. Luckily, there is an upcoming W3C WebSockets standard. This talk will discuss use cases for WebSockets, show you compatibility issues/fallbacks and different ways of dispatching your events. You will learn about fully-asynchronous stateful applications, but also about how to enhance existing apps with realtime capabilities.
