PHPWEBSOCKET
============

So here is a quick hack to implement websockets in php.  
As of Feb/10 the only browsers that support websockets are [Google Chrome](http://www.google.com/chrome) and [Safari nightlies](http://nightly.webkit.org/)

Changelog
---------
* 2010.02.18 - Chatbot demo extending websocket class
* 2010.02.18 - Websocket class for better reuse
* 2010.02.15 - Added Users list to keep track of handshakes
* 2010.02.15 - Minor cosmetic changes

Client side
-----------

View source code of [client.html](http://github.com/GeorgeNava/phpwebsocket/blob/master/client.html)

Server side
-----------

log("Handshaking...");
	list($resource,$host,$origin) = getheaders($buffer);
	$upgrade = "HTTP/1.1 101 Web Socket Protocol Handshake\r\n" .
			   "Upgrade: WebSocket\r\n" .
			   "Connection: Upgrade\r\n" .
			   "WebSocket-Origin: " . $origin . "\r\n" .
			   "WebSocket-Location: ws://" . $host . $resource . "\r\n" .
			   "\r\n";
	$handshake = true;
	socket_write($socket,$upgrade.chr(0),strlen($upgrade.chr(0)));

Steps to run the test:
----------------------

* Save both files, client.html and server.php, in a folder in your local server running Apache and PHP.
* From the command line, run the server.php program to listen for socket connections.
* Open Google Chrome and point to the client.html page
* Done, your browser now has a full-duplex channel with the server.
* Start sending commands to the server to get some responses.

WebSockets for the masses!
