如何推送通知的工作？ [英] How do push notifications work?
问题描述
我想实现我的基于PHP的网站推送通知。我们的目标是使类似的东西到什么＃1和其他网站都该通知时，他们得到的消息实时的用户。
I'm trying to implement push notifications on my PHP-based website. The goal is to make something similiar to what Stackoverflow and other sites have which notify a user in real-time when they get messages.
我使用MySQL作为我的数据库，Apache作为我的服务器，并使用亚马逊SNS作为，因为这些通知的框架，正在考虑是什么，服务似乎打算。
I'm using mysql as my database, Apache as my server, and am considering using Amazon-SNS as the framework for these notifications since that is what that service seems to be intended for.
我有从文献很难理解如何编程的 sending.php 和 receiving.php 页都成立。我假设 sending.php 页面只是涉及 $ _ POST ['消息'] 来一些网页，但从那里，我真的失去了。
I'm having a hard understanding from the literature how programmatically the sending.php and receiving.php pages are set up. I'd assume the sending.php page just involves a $_POST['message'] to some page, but from there I'm really lost.
如果事情能帮助我理解 receiving.php 页会是什么样子的推送通知我将不胜AP preciate它。
If something could help me understand what the receiving.php page would look like for a push notification I would greatly appreciate it.
推荐答案
HTML5ROCKS在这里提供了很好的解释 ，如何的WebSockets的工作。
Working
HTML5rocks have provided a good explanation here, about how websockets work.
那么你可以使用WebSockets，为支持它（因为所有现代浏览器都提供良好的支持）
Well you can make use of Websockets for the browsers that support it (since all modern browsers provide good support)
您可以开始使用这几个资源：
You can get started with these few resources :

NETTUTS +入门与<一个提供一个很好的教程href=\"http://net.tutsplus.com/tutorials/javascript-ajax/start-using-html5-websockets-today/\">websockets.
Nettuts+ provide a good tutorial for getting started with websockets.
您可以使用 Modernizr的以检测客户端的浏览器是否有支持的WebSockets与否＆功放;作为后备，你可以利用闪存来代替的WebSockets的。
You can use Modernizr to detect whether the Client's browser has support for websockets or not & as a fallback you can make use of flash instead of Websockets.
有关的项目，没有的WebSockets或在浏览器中运行时，它禁用，网络插座JS 将会被使用。这将是比本地效率不高，但比长轮询仍然低得多的延迟。
For those projects, when running on browsers with no WebSockets or with it disabled, web-socket-js will be used. It will be less efficient than native, but still much lower latency than long-polling.
与Flash任何浏览器都可使用网络插座JS 垫片/填充工具支持WebSocket的。
Any browser with Flash can support WebSocket using the web-socket-js shim/polyfill.
