PHP: Retrieving the Country Associated with an IP Address

This question explores the possibility of using PHP to determine the country corresponding to a given IP address. Is there a viable PHP solution or a superior alternative?

PHP Solutions

As mentioned in the provided answer, there are multiple free APIs available for this purpose, including:

• ipinfodb.com/ip_location_api.php
• ipgeo.com/api/
• ip2.cc/
• geobytes.com/IpLocator.htm
• iplocate.io/

Utilizing these APIs, you can quickly retrieve the country information. Alternatively, you could employ scripts based on local databases like:

• phpweby.com/software/ip2country

Additional Considerations

The answer suggests considering HTML5 Location features for certain scenarios. While this approach is not universally supported, it offers an alternative for mobile and compatible browsers.

Updates

The answer was updated in April 2013 to highlight Geocoder, a PHP library that streamlines geolocation tasks, including IP address geocoding.

In September 2016, it was noted that Google's privacy policies require HTTPS certification or user consent for accessing location data via HTML5 Geolocation API. Therefore, relying solely on IP-based country determination or obtaining HTTPS certification is recommended.
