GeoIP + PHP usage

Copy CodeThe code is as follows:
Include ("geoip.inc.php");
Open Data File
$gi = Geoip_open ("GeoIP.dat", Geoip_standard);
Get Country Code
$country _code = geoip_country_code_by_addr ($gi, $_server[' remote_addr ']);
echo "Your Country code is: $country _code";
Get Country Name
$country _name = geoip_country_name_by_addr ($gi, $_server[' remote_addr ']);
echo "Your country name is: $country _name";
Close File
Geoip_close ($GI);
Note: If you test locally because $_server[' remote_addr ' and $_server[' REMOTE_ADDR '] may be 127.0.0.1, the output content is empty. Can bring in the IP test yourself
