php websocket device server
#!/usr/bin/php
<?php
/* websocket/device server program for raspberry pi
* this program only deals with packets that are 125 bytes max
* currently only one client can connect at a time. Maybe not a bad thing.
* run as super user (for gpio access)
* check out https://gist.github.com/BobBurns/6f83930912da4094f014 for the client html code
* much of the juicy bits adapted from ghedipunk/PHP-Websockets
