用php驱动的网站实现Comet [英] implement comet with php driven website

问题描述

我想知道是否有人可以用一些简单的术语来解释我如何让
从彗星开始。我在共享主机环境中。

I wanted to know if somebody could explain in somewhat simple terms how I could get started with comet. I am on a shared host environment.

我的可能性到底是什么？

What exactly are my possibillity's?

从这里我读到的内容Sofar认为php不是最佳选择，因为
是每个请求一个进程运行，而不是在线程外运行。
另外，他们谈论套接字。

From what I have read here sofar, is that php is not the best option., because it is run as a one process per request instead off thread. On another, they talk about sockets.

我也读过有关facebook的信息，他们在那里运行着用erlang编写的自己的彗星服务器，但是它们仍然有一个php网站。那么，那到底是如何工作的呢？

I have also read about facebook and that they run there own comet server written in erlang, but they still have a php website. So how exactly does that work then?

我现在已经阅读了很多东西，但是在我的情况下
到底有什么可能还是有点含糊。运行一个彗星服务器上的客户端的PHP脚本？这并不是说它如何保持持久的开放连接！ （只是抛出其他帖子的一些评论）

I have read alot off stuff now, but it is still a bit vague on what is actually possible in my situation. Running a php script that is a client off a comet server?? That is not saying how it keeps a longlasting open connection! (just throwing in some comments from other posts)

谢谢，理查德

推荐答案

您可以使用PHP重现Comet行为。就像您说的那样，PHP并不是最佳选择，因为仍然存在许多内存管理问题。

You can use PHP to reproduce the Comet behavior. Like you said PHP isn't the best choice because of a lot of memory management issues that are still widely there.

但是对于小规模用途（低流量）PHP会正常工作。

However for small scale purposes (low-traffic) PHP will work just fine.

网络上有很多关于Comet的信息，以及如何将其与Python或Erlang等语言结合使用（由于它的最佳并发性，所以特别好）行为，但坦率地说，我对此了解不多。）

There's a lot of information on the web about Comet and how to use it with languages such as Python or Erlang (especially good because of its optimal concurrency behavior, but frankly I don't know much about it).

如果您想尝试使用Python，SO上会有一个很好的问题/答案：
