问题描述
确实有人知道如何实现类似Facebook的通知？这个想法是把通知在平行于无刷新该网站数据库中所做的更改标签？如果一个数据被添加到数据库中，该网站应反应就可以了。谢谢你..干杯！

推荐答案
Facebook的风格通知正在使用的如彗星服务器或WebSocket的服务器。它可以直接添加此功能集成到一个PHP应用程序，但它被广泛认为PHP不处理持久性/长期持有的连接非常好（不会比例）。如果你仍然想在这里举办自己的实时PHP的解决方案有一些资源：
Facebook style notifications are achieved in web applications using realtime web technologies such as Comet servers or WebSocket servers. It is possible to add this functionality directly into a PHP application but it's widely agreed that PHP doesn't handle persistent/long-held connections very well (it won't scale). If you still want to host your own realtime PHP solution here are a few resources:
- StackOverflow question about AJAX PHP Push
- phpwebsocket
- Start using HTML5 WebSockets today
- php-websocket
- How to implement Comet in PHP
不过，我建议你看一下href="http://www.leggetter.co.uk/real-time-technologies-guide#hosted-services">托管解决方案一个 SO质疑>
However, I'd recommend you look at a hosted solution (I work for one such company) which means all you need to do is make a HTTP call to a RESTful API and embed a JavaScript library within your application to achieve your push notifications. More information why I recommend using a hosted service in this SO question on Apache and Comet
