API: PHP Query

Hi there,

I have a query regarding PHP API usage.

Can you use multiple country codes for the below code- For the example below I have used 3 countries: DE,GB,US

if (function_exists(‘geoip_detect2_get_info_from_current_ip’)) {
$userInfo = geoip_detect2_get_info_from_current_ip();
if ($userInfo->country->isoCode == ‘DE,GB,US‘) {
echo ‘Hallo! Sch?n dass Sie hier sind!’;
}
} else {
echo ‘<!– Warning: The plugin Geolocation IP Detection is not active. –>’;
}

Or is it only possible to enter one country code here?

Thanks
