title: httpServer to execute PHP script
body: <p>I am writing a java http server and I have completed FileServer class to handle requests (Get, Head, Post, etc) for normal files like index.hitml<br>
  I also want to enable my server to execute PHP scripts and return the output to clients.
       "http://localhost/phpinfo.php "</p>
  
  <p>How can I do that? I need some resources.
  Please point me to any resources or apis to read :)<br>
  Thanks</p>
