推荐答案

使用PHP来轮询或尝试实现基于推送的解决方案，如果你将有任何可观的流量。会发生什么，最终所有的PHP进程被阻塞，然后你不能再提供Web请求。

I wouldn't advise using either polling or trying to implement a push based solution using PHP, if you are going to have any sizable traffic. What happens is that eventually all the PHP processes get blocked, and then you can't serve anymore web requests.

查看node.js，cometd或其他基于推送的解决方案。如果您需要简单的操作并需要快速启动和运行，我建议您 http://pusherapp.com/ 。他们有一个PHP客户端可用和超级简单的API。
