推荐答案

我不会建议使用两种轮询或试图实现使用PHP推的解决方案，如果你打算有任何可观的流量。什么情况是，最终所有的PHP进程被阻塞，然后你就不能成为了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.

查找到的node.js，cometd或其他推送的解决方案。如果你需要的东西简单，需要得到快速启动和运行，我建议 http://pusherapp.com/ 。他们有一个PHP客户提供超级简单的API。

Look into node.js, cometd or another push based solution. If you need something simple and need to get up and running quickly, I'd recommend http://pusherapp.com/. They have a PHP client available and super simple API.
