Artificial geo targeting for Chitika and Adsense

Anyone know how to write a script for that?

[spica42]

Well, Chitika doesn't accept clicks from outside US etc.. Is it possible to write a script so that traffic outside USA will see google ads instead?

function geolocation()
{
 include_once('./geoip.inc');
 $gi = geoip_open('./GeoIP.dat', GEOIP_STANDARD);
 $countrycode = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
 geoip_close($gi);
 return in_array($countrycode, array('US', 'GB', 'FR', 'CA', 'AU', 'NZ'));
}

Returns true if user is from supported country.
