软件介绍

从名字上也可看出，这是一个 WebSocket 的 PHP 实现。

示例客户端代码：

var host = "ws://localhost:12345/websocket/server.php";
try{
  socket = new WebSocket(host);
  log('WebSocket - status '+socket.readyState);
  socket.onopen    = function(msg){ log("Welcome - status "+this.readyState); };
  socket.onmessage = function(msg){ log("Received: "+msg.data); };
  socket.onclose   = function(msg){ log("Disconnected - status "+this.readyState); };
}
catch(ex){ log(ex); }

示例服务器端代码：

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,$upgrade.chr( ),strlen($upgrade.chr( )));
