I am currently working on an online presentation tool. Consider the following scenario:
我目前正在开发一个在线演示工具。请考虑以下情形：
- Someone gives a presentation
- 有人发表了演讲
- another person connects to watch said presentation
- 另一个人连接观看所述演示文稿
- >> I want to update the watcher's view when the presenter changes the slide
- >>我想在演示者更改幻灯片时更新观察者的视图
what would be the better approach?
什么是更好的方法？
- forcing the connection to stay open to send updates onSlideChange
- 强制连接保持打开以发送更新onSlideChange
- periodically (every second or so) letting the client request an update
- 定期（每隔一秒左右）让客户请求更新
- something else I am not aware of
- 我不知道的其他事情
Thanks!
谢谢！

I would suggest using websockets for this, however your websocket would have to be a separate application running through a higher level PORT on your server.
我建议使用websockets，但是你的websocket必须是一个单独的应用程序，通过服务器上的更高级别的PORT运行。
There are a few PHP websocket tools out there, have a look at http://socketo.me/ (as this was the first result on google!) or you could write one with PHPs Socket methods, but you will need to do some reading on Websocket standards and handshake decryption.
