问题描述
我正在业余时间慢慢地学习和学习Redis，我对可用于为订阅频道的网站创建侦听器"并在收到消息时更新网页的选项感兴趣.
I'm slowly digging in and learning redis in my spare time, and I am interested in the options available for creating a 'listener' for a website that subscribes to a channel, and updates a webpage as messages are received.
现在，从我过去的动作脚本时代和当前的javascript工作开始，鉴于这两种语言，我对听众的概念非常熟悉.但是，我的服务器端编程功能实际上仅扩展到PHP，一些rails，一些python和伪node.js(我是一个非常有经验的javascript专家，并且了解node.js的作用).
Now, from my old actionscript days, and current javascript work, i'm quite familiar with the concept of listeners given those two languages. However, my server-side-programming-fu really only extends as far as PHP, a bit of rails, a bit of python, and pseudo node.js (i'm a fairly experienced javascript guy, and understand what node.js does).
由于我的主要技能在于php，所以我想知道是否甚至可以与php进行持久连接/套接字，从而在PHP中创建侦听器?
Since my main skill set lies in php, i'm wondering if it is even possible to do a persistent connection/socket with php and thus create a listener in PHP?
由于我猜想这实际上是不可能的(或者等效于用锤子修复挡风玻璃裂缝)，服务器端有哪些选择?是否可以仅创建一个JavaScript侦听器，该侦听器使用与Redis服务器的持久连接(当前在localhost上).我应该研究Socket.io吗?
Since i'm guessing this isn't actually possible (or is the equivalent of fixing a windshield crack with a hammer), what are some server side options? Is it possible to just create a javascript listener that uses a persistent connection to the redis server (currently on localhost). Is Socket.io something I should look into?
任何对Redis初学者的见识将不胜感激.
Any insight for a redis beginner would be much appreciated.
编辑我在部分回答了我的问题.
edit I found a great post here How to use redis PUBLISH/SUBSCRIBE with nodejs to notify clients when data values change? that partially answers my question.
除了node.js之外，还有没有一种方法可以完成相同的工作?我可以完全放弃php并为此项目尝试一些新的东西.无论如何都是个人的.
Is there a method aside from node.js that does the same thing? I'm ok with dropping php completely and trying something new for this project. It's a personal one anyways.
推荐答案
PubSubContext 和 DispatcherLoop 示例是您要在PHP中尝试实现的目标的不同实现.
The PubSubContext and DispatcherLoop examples from the Predis source code on Github are varying implementations of what you are trying to achieve, in PHP.
