The website uses an free external website called hostip.info to extract the location from the incoming ip address. The HTML code creates a small hyperlink image which directs the user to the main Geovisitor page displaying their geolocated hits on a google map. Now I know this isn't an amazingly unique idea but I must admit it hasn't be done with this kind of style before.

He walks through the steps:

• parsing out the XML from the result call to hostip.info
• setting up a database to record the information
• displaying an image on the same page with a RewriteRule
• integrating the information into a Google Map (via the API)

Sounds simple, right? Well, have no fear - there's plenty of explaination the whole way through, so you won't be at a loss.
