I'm one of the core maintainers of Yii PHP framework for more than 7 years, its representative in PHP-FIG, active conference speaker and participant of various other OpenSource projects.
The talk goal is to try to understand the direction frameworks and PHP are heading to and how that's connected with the business needs, developer needs, web trends and more. Hope there will be less questions like "what should I learn" or "what framework should I use".
