Sending stream responses with Zend Framework 2, Part 1

Sending stream responses is a new feature in Zend Framework 2.1. This short introduction will help you getting startet on how to send stream responses in Zend Framework 2.
Most times an application would deliver file downloads or video streaming with static assets, delivered directly frm Apache or Nginx. But sometimes there are restrictions: Only logged-in users should be able to download this file, watch this content, perhabs even a more complicated permission system. Then the application needs to do some permission checks and stream the response.
In this example we assume a simple file download, we deliver the file as stream response, because this is much less memory consuming and more efficient, compared to grabbing the file content and pushing it to the response body of the default response object.

Even more complex use cases with download resume and speed limits are also possible in the future, but this is part of my next blog post about this topic. However you can see how easy it is to send stream responses with Zend Framework 2. As we return the response object directly in the controller, no view is created and rendered, too, so this is really a very fast operation.
