Php Chat Script Query

Hi,

I'm making a chat room for my site and have everything coded apart from the part that will recall the mysql query every few seconds to get and send the messages to the database,

Are there any tutorials on how to do this or could anyone help me out with a small section of code?

I believe this can be done with ajax/javascript?

Thanks for your time,

Dan

 

This is a good Example Tutorial:

Hope you will learn something from it

 

Thanks for that, I've looked into that script before and although its good the queries lag quite a bit,

As i said i do have the whole chatroom coded but all i need is a way to refresh the mysql queries and i'm not sure how to do that part.
