Following yesterday's article on returning JSON from a ZF2 controller action, Lukas suggested that I should also demonstrate how to use the Accept header to get JSON. So this is how you do it!

You'll need to create the JsonStrategy first, then you can return the ViewModel from the controller. If all goes well, you should see the sample HTML page rendered in a browser and JSON output when requested with the right "Accept" header (he uses curl in his example).
