PHP gets current geographical location interface based on IP address

function address_baidu($ip) {
 $u = "";
 $address = file_get_contents(" http://open.baidu.com/ipsearch/s?wd={$ip }&tn=baiduip");
 preg_match('#From: (.+)#Ui', $address, $m);
 return strval($m[1]);
 }
function GetRemoteIp($default='127.0.0.1')
{
 $ip_string = $_SERVER['HTTP_CLIENT_IP'].','.$_SERVER['HTTP_X_FORWARDED_FOR'].','.$_SERVER['REMOTE_ADDR' ];
 if ( preg_match ("/d+.d+.d+.d+/", $ip_string, $matches) )
 {
 return $matches[0];
 }
 return $default;
}
$ip = GetRemoteIp ();
$addr = address_baidu($ip);

There are other methods: Tencent Sina's interface to obtain the current geographical location (province) through IP address
