从长轮询更改为PHP WebSockets/常规套接字？

在我最终总结了一些关于不同问题的东西之后，我想我应该把注意力转移到我以前的一个项目上，我想进行升级

我有一个PHP聊天室，我被告知它使用长轮询在我的网站（由WAMP服务器托管）上的用户之间发送和接收消息。告诉我这是一项长期调查的同一个人建议我使用Web套接字。我发现PHPWebSockets只与支持HTML5的浏览器兼容，尽管最近另一位朋友向我指出，这些浏览器之间的兼容性非常低

无论如何，在这一点上，我想建立一个Android应用程序，将连接到这个聊天室。我应该使用PHP WebSocket吗？还是普通插座

最后，我需要做些什么才能使这项改革成为当前的代码，我必须把我的聊天室变成一个更加基于套接字的工作

这是我的档案
