This script can be used to implement a simple Web based chat system that uses AJAX to update the chat dialog display area without reloading the whole page. AJAX driven simple chat script is a free PHP chat script.

The script generates a page with a Web form to submit what each chat line that the users type.

The chat lines are sent to the server using a XMLHttpRequest object.

The chat lines are received by a server side script that uses the class to store what each user entered in a MySQL database table.

In response, the script outputs the chat list already formatted to by displayed in the user browser pages.
