如何在PHP中实现推送通知 [英] How to Implement Push Notifcation in PHP

问题描述

我已经和ajax合作了一段时间了，我已经用它做了很多漂亮的工作..但是我最近的挑战是关于推送通知。

I have been working with ajax for a while now, and I have used it to do a lot of nifty jobs.. But then my recent challenge has been on push notification.

我想实现一个不需要在每个时间段内调用服务器的站点，而只是在特定数据库字段有更新时才调用服务器，我想要在PHP，javascript和/或jquery或任何其他Web技术中实现这一点。我不知道如何去做，或者甚至可能。

I want to implement a site that would not need to make a call to the server every period of time, but rather would make a call to the server only when there is an update on a particular DB field, and I want to implement this in PHP, javascript and/or jquery or any other technology for the web. I do not have any idea as to how to go about it, or if it is even possible.

我想知道在何处以及如何开始的指示，谢谢大家。 ....

I would like directions on where and how to start, Thanks all.....

推荐答案

由于WebSocket支持尚未完全支持，您可能希望重新进行长轮询。似乎已经有一个jQuery插件：

Since WebSocket support isn't quite there yet, you would want to fall back on long polling. There already seems to be a jQuery plugin for this:
