WebSocket 的 PHP 实现 - phpwebsocket

从名字上也可看出，这是一个 WebSocket 的 PHP 实现。

示例客户端代码：

1var host = "ws://localhost:12345/websocket/server.php";

2try{

3  socket = new WebSocket(host);

4  log('WebSocket - status '+socket.readyState);

5  socket.onopen    =function(msg){ log("Welcome - status "+this.readyState); };

6  socket.onmessage =function(msg){ log("Received: "+msg.data); };

7  socket.onclose   =function(msg){ log("Disconnected - status "+this.readyState); };

8}

9catch(ex){ log(ex); }

示例服务器端代码：

01log("Handshaking...");

02list($resource,$host,$origin) = getheaders($buffer);

03$upgrade = "HTTP/1.1 101 Web Socket Protocol Handshake\r\n" .

04           "Upgrade: WebSocket\r\n".

05           "Connection: Upgrade\r\n".

06           "WebSocket-Origin: ". $origin . "\r\n" .

07           "WebSocket-Location: ws://". $host . $resource . "\r\n".

08           "\r\n";

09$handshake = true;

10socket_write($socket,$upgrade.chr( ),strlen($upgrade.chr( )));
