refresh the webpage on database update

I want to reflect the changes that occur immediately in the table in a database, on the webpage. I have been reading about websockets but I am not very clear about how to implement it. I was wondering that how could I be able to extract that new information is has been added to the table and how do I let the server push it tow开发者_开发技巧ards the browser.

For pushing data to the users I tried with success http://pusherapp.com/.

As of how to reflect the change on the database to PusherApp, it depends on your architecture. If you have a beforeSave() callback, or you centralize SQL queries on one file, that's the place to handle it, if not you'll have to track all the places where you need to implement this behavior.

You could also try a comet application i.e. longpollig - http://www.zeitoun.net/articles/comet_and_php/start
