Grabbing visitors OS, state, isp, city info

Hi,

Everything else is fine, except OS, state, isp, city that I haven't managed to gather. Any ideas?

Grab the IP and then you have to use a service to retrieve that information. (not OS). I use ippages.com and I query their database with the use of SOAP.

try this:

http://www.maxmind.com/app/ip-location

This will get the OS along with browser.

$_SERVER['HTTP_USER_AGENT']
