Ways to get their geographic location (provinces, cities, etc.) based on existing IP addresses

function Getiplookup ($ip = ") {    if (empty ($ip)) {      return ' Please enter the IP address ';   }    $res = @file_get_contents (' http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip= '. $ip);    if (empty ($res)) {return false;}    $jsonMatches = Array ();    Preg_match (' #\{.+?\}# ', $res, $jsonMatches);    if (!isset ($jsonMatches [0])) {return false;}    $json = Json_decode ($jsonMatches [0], true);    if (Isset ($json [' ret ']) && $json [' ret '] = = 1) {      $json [' ip '] = $IP;      unset ($json [' ret ']);    } else{      return false;    }    return $json;  } $ipInfos = Getiplookup (' 123.125.114.144 '); Baidu.com IP Address

var city= ' <?echo ipCity ($xp _userip);? > '; Jump to a specific page based on IP address for all cities

if (City.indexof ("Shanghai City") >=0) {

Window.location.href= "http://shanghai.demo.com/"; }
