Using AJAX from PHP is very easy. All you need is the JavaScript functions for sending the XMLHttpRequest and then handle the Http Response. It will simplify development since you place all your AJAX related code in a single JavaScript file and reference it from anywhere you need AJAX.

There is another way of getting the same result from PHP without using the XMLHttpRequest object. I personally do not like the concept because it is missing one of the main ingredients of Asynchronous JavaScript and XML (AJAX), XML. This concept is good for the old browsers with no supports for XMLHttpRequest object, but as all the newer versions are supporting XMLHttpRequest object you can use AJAX for the common browsers.
