title: Explain PHPNG (next generation) and how to use it
body: <p>So I have done a few Google searches and I cannot find an answer to my questions. I noticed PHPNG was in the master in PHP 7.0 so I'm guessing we can use it with the release of PHP 7.0.</p>
  
  <p>My questions are:</p>
  
  <ul>
  <li>how do we use phpng (specifically with nginx)?</li>
  <li>what should we be using it for (dev, production etc)?</li>
  <li>does anyone even use it?</li>
  </ul>
  
  <p>Thanks in advance</p>
