软件概览
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( )));
