title: OAuth 2.0 Server for PHP
body: <p>I have been struggling to find an active open-source PHP project that supports OAuth 2.0 as a server. There are tons of client examples that connect to Facebook, Twitter, etc. but as more and more people want to expose their own services through an API I'm a bit surprised the open source community hasn't addressed this need already. It's not that there is <strong>nothing</strong> but what's there is mostly out-of-date, little-to-no documentation, and very little to no activity in terms of current development and conversation. </p>
  
  <p>Am I missing a good open-source option out there? Does anyone know of any commercial options? I really need to get something in place soonish and I personally don't have the bandwidth or security credentials to tackle this problem myself.</p>
