Jason Gilmore has posted the first tutorial in a series of tutorial combining PHP and jQuery, a look at creating a web site visitor map.

Have you ever wanted to create a map depicting the geographical origin of recent visitors to your website? In this tutorial I'll show you how to record these locations using the Google Ajax Search API, and then use a combination of PHP, MySQL, Ajax, and the Google Maps API to store these locations and build the map.

The tutorial shows how to use the Google Ajax API to locate the current visitor's spot in the world, store it into a MySQL database and then use a jQuery interface to pull the json-formatted details out of the system for display.
