title: Does Nodogsplash on Raspberry Pi 3 support PHP?
body: <p>I am setting up a captive portal using Nodogsplash, on a Raspberry Pi 3. The landing web page is a form with an action that points to a PHP file. While this works elsewhere, with Nodogsplash I get "Error 503".</p>
  
  <p>I am wondering if Nodogsplash supports PHP by default, and if not, is there a way to set it up support PHP.</p>
  
  <p>Thanks</p>
