I am assuming that Ajax is a part of JavaScript right? (I have never done ajax before)...

But I need a way to change values of php variable.....im not looking for a script necessarily but a good tutorial that can guide me.....

This link does a pretty good job of explaining and there are a couple of examples using PHP on the server side - http://w3schools.com/ajax/default.asp

Basically, a http request is made to a URL (ie. yourscript.php). It is up to the server side code to receive any post/get data that is sent and change any variables. It is not possible to change any variables directly (unless you have register globals on.)
