Tool or PHP code to convert IP address into lat/lng coordinates [closed]

Answer 1

For one of my sites I made use of maxmind's free geolite country database which can be downloaded here: http://www.maxmind.com/app/geolitecountry

They also provide a city level version which includes the long/lat: http://www.maxmind.com/app/geolitecity

but note that the accuracy on the free version is a lot lower than the paid version.
