Description
WebSocket Server and Client library for PHP. Works with the latest HyBi specifications, as well the older Hixie #76 specification used by older Chrome versions and some Flash fallback solutions.
This project was started to bring more interactive features to http://www.u2start.com/
Downloads
Currently no downloads are available. Source and simple example available in GIT repository (see Source tab).
Features
Server
Hixie #76 and Hybi #12 protocol versions Flash client support (also serves XML policy file on the same port) See https://github.com/gimite/web-socket-js for a compatible Flash Client Native Firefox, Safari (iPod / iPhone as well), Chrome and IE10 support. With Flash Client every browser supporting Flash works as well (including IE6-9, Opera, A2本文来源gaodaima#com搞(代@码$网6

ndroid and other older desktop browsers). Opera (Mobile) supports WebSockets natively but support has been disabled by default. Can be enabled in opera:config.
Client
Hybi / Hixie76 support. Known Issues SSL support not well field tested. Lacks ORIGIN checking (can be implemented manually in onConnect using getHeaders(), just disconnect the user when you dont like the Origin header) No support for extension data from the HyBi specs. Requirements
Server
PHP 5.3 Open port for the server PHP OpenSSL module to run a server over a encrypted connection
Client
PHP 5.3 Server that implements the HyBi (#8-#12) draft version PHP OpenSSL module to connect using SSL (wss:// uris) Server Example

Client Example
The Client is not as interesting as the server and is mainly used to test the server
<?php require_once("websocket.client.php"); $input = "Hello World!"; $msg = WebSocketMessage::create($input); $client = new WebSocket("ws://127.0.0.1:12345/echo/"); $client->sendMessage($msg); // Wait for an incoming message $msg = $client->readMessage(); $client->close(); echo $msg->getData(); // Prints "Hello World!" when using the demo.php server
?>
