How to Install the PHP GeoIP Extension?


GeoIP introduces to the way of establishing a computer terminal’s geographic location by recognizing that terminal’s IP address. Though GeoIP can pinpoint a terminal’s location in a city, it needs the use of a GeoIP database as strong as an understanding of APIs to achieve correctly.

Furthermore, GeoIP is not as reliable as other methods of geolocation, such as GPS and mobile technology, though no geolocation system passes complete accuracy. It is also possible for experienced users to cover or alter their apparent location from GeoIP systems.

Applications:

1) Involves geo-targeting or determining a computer’s location.
2) Most often used for targeted advertising, statistical research, spam prevention.
3) Also for restricting access based on location.
