GeoLocation?

Is there a GeoLocation library/helper/class available for use in Code Igniter?

If so, can I get a URL to a guide (that I haven't yet been able to find that tells me how to make use of it)?

If not, can I get a URL to a guide that can help me figure out how to implement it into my project?

There are several geolocation packages available on packagist.org. You use them via composer.

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
