推荐答案

最常用的方法称为这是一个PHP实现:如何使用PHP实现COMET

Here is a PHP implementation: How to implement COMET with PHP

在HTML5规范中，已经有许多浏览器实现了所谓的Websocket.这是一个支持websocket的PHP项目: phpwebsocket .如果浏览器不支持websocket(因此向后兼容)，则有一些javascript库可以使用Flash组件

In the HTML5 specification there are something called websockets that many browsers already have implemented. Here is a PHP project supporting websockets: phpwebsocket. There are some javascript libraries which can use a flash component if the browser do not support websockets (and therefore be backwards compatible)

imho webSockets是可行的方法，尽管PHP可能不是最适合处理它们的后端.

imho webSockets is the way to go, although PHP might not be the most suitable backend to handle them.
