In the last couple of years I’ve seen many different applications: Spaghetti code, framework based apps, good or bad code quality. But there’s one thing most of them have in common at a certain point in time: For different reasons it’s hard to migrate to the state-of-the-art programming methodology. And now Zend Expressive comes into play. Zend Expressive is not only a slim middle-ware framework which implements the PSR 7 standard. Thanks to it’s simple base concept Expressive is great as a quick start for your migration project and a smooth transition to the next generation of the app. See in this session best practices on how to bridge your legacy system – like a ZF 1 or Symfony 1 application – to Expressive and move it to the next level.
