How to get Geolocation using PHP cURL from IP Address
What is Geolocation
Geolocation is a method for mapping the virtual identity of an internet-connected device to its physical address. A virtual identity is represented by an Internet Protocol (IP) address. The physical address is the location of this device within the geographic area of the earth, represented by latitude and longitude. It can still be extrapolated to a geopolitical or postal or zip code address that we use on a daily basis to identify a place.
