PHP Geo IP Locator
Very useful function for tracking your visitors, localized languages, auto completion of registration forms (address) and anything you can think of.
function geoip($ip = "127.0.0.1"){
if($ip == "127.0.0.1"){$ip = $_SERVER["REMOTE_ADDR"];}//if no IP specified use your own
$ch = curl_init();//faster than file_get_contents()
curl_setopt($ch, CURLOPT_URL,'http://www.geoplugin.net/php.gp?ip='.$ip);//fetch data from geoplugin.net
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$curl = curl_exec($ch);
curl_close($ch);
$geoip = unserialize($curl);
return $geoip["geoplugin_countryName"]." ".$geoip["geoplugin_city"];//return country and city
}
Let's find out where is Google (according to IP)...
