javascript - 浏览器中使用websocket有什么好的库？
要支持IE8以上的。网上一搜都是socket.io但是这个也好配合node.js使用。
我的服务端使用的是php。

PHP写WebSocket需要自己处理原始数据，前端库本质上只是一种常用方法的封装，socket.io就可以。
WebSocket是HTML5 API，是内置在浏览器内部的高级特性，IE8绝对不支持，而且客户端javascript也没有牛逼到可以自定义协议的地步，所以，老浏览器只能继续使用轮询。
使用web-socket-js，在低版本浏览器下会使用flash来完成socket通信，不过他也有个缺点，就是只支持发送文本数据，如果你的数据包格式设计成二进制的，那就不支持了。
如果坚持服务器端用PHP的话 推荐几个框架 swoole 和 workerman
see workerman-chat,好像用的 web-socket-js
