推荐答案
我不建议使用轮询或尝试使用 PHP 实现基于推送的解决方案，如果您将有任何可观的流量.发生的情况是，最终所有 PHP 进程都被阻止，然后您就无法再处理 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.如果您需要一些简单的东西并且需要快速启动和运行，我建议您使用 http://pusherapp.com/.他们有可用的 PHP 客户端和超级简单的 API.
