Hi,

I need to get the nearest neighbor state based on the IP address of the current state. I have done some research and found Geo plugin, which gives the state information based on the IP address. So now i need the States nearer to that IP address.How can i do it in PHP..? can any one suggest me..

Thank you.

The Geolocation API can probably be more accurate, check for:
