Get country from ip

<?
// Let me start off by saying I do not take full credit for this!
// I needed a way to get my traffic's country for Adverts...
// for some reason, json_decode wasn't working, so this is an alternative.
// json_decoder function from PHP.net
// file_get_contents_curl basic data retrieval function
// how to use:
// include('country.php');
// $userCountry=getTheCountry();
// output is 2 character country code, US, CA, etc...
