Best way for real-time HTML/AJAX/PHP chat
提问by xwinus
I have to create a little AJAX chat in my web application and I'm dealing with problem of real-time communication between javascript client and PHP server. I want my js client to be able to catch new messages from the server as quick as possible. My first idea was to create AJAX request for example each 5 sec. to see whether there are new messages. However, I'm not sure what happens if my application use for example 1000 people, it must be huge load to Apache httpd. I also know about technique called 'long-polling' request, but when I tried that locally on my server, I've completely shooted down my Apache (I've read sth about problems with apache and long-polling). The next way I know about is WebSocket. However, is it true that I have to be able to open port on webserver to use it? Because on regular web hosting, I thing it's not possible and I cant change any Apache/PHP settings on my hosting. Do you have any suggestions how to solve it?
我必须在我的 web 应用程序中创建一个小的 AJAX 聊天，我正在处理 javascript 客户端和 PHP 服务器之间的实时通信问题。我希望我的 js 客户端能够尽快从服务器捕获新消息。我的第一个想法是例如每 5 秒创建一次 AJAX 请求。查看是否有新消息。但是，我不确定如果我的应用程序使用例如 1000 人会发生什么，这对 Apache httpd 来说一定是巨大的负载。我也知道一种叫做“长轮询”请求的技术，但是当我在我的服务器上本地尝试它时，我已经完全拒绝了我的 Apache（我已经阅读了一些关于 apache 和长轮询的问题）。我知道的下一个方法是 WebSocket。但是，我必须能够在网络服务器上打开端口才能使用它，这是真的吗？因为在常规的网络托管上，我认为这是不可能的，我无法更改主机上的任何 Apache/PHP 设置。你有什么建议如何解决吗？
Thank you and excuse my english please, I'm not native.

You should use php comet and push from the server instead of doing requests.
您应该使用 php comet 并从服务器推送而不是执行请求。
