Example code for PHP to determine locale name information based on IP

  This article mainly introduces PHP based on IP to determine the region name information method, the need for friends can refer to the following

See Code     code as follows: <?php  header ("content-type:text/html; Charset=utf-8 ");  function GetIP () {  if (Isset ($_server)) {  if (Isset ($_server[http_x_forwarded_for)) {  $realip = $_server[http_x_forwarded_for]; } elseif (Isset ($_SERVER[HTTP_CLIENT_IP))) {  $realip = $_ server[http_client_ip]; } else {  $realip = $_server[remote_addr]; } } else {  if (getenv ("HTT P_x_forwarded_for ")) {  $realip = getenv (" Http_x_forwarded_for "); } elseif (getenv (" Http_client_ip ")) {   $realip = getenv ("Http_client_ip"); } else {  $realip = getenv ("remote_addr"); }  ret Urn $realip; }    $IP = GetIP ();   //Use Sina interface based on IP query area information   * $res 0 = file_get_contents ("HT tp://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip= $ip ");  $res 0 = Json_decode ($res 0);   Print_r ($res 0);  echo "<br/>"; */   //using Taobao interface based on IP query area information   $res 1 =File_get_contents ("http://ip.taobao.com/service/getIpInfo.php?ip= $ip");  $res 1 = json_decode ($res 1); /* Print_r ($res 1); */    How to read the data, look below. The   code is as follows: $array = Get_object_vars ($res 1);//assignment to array   foreach ($array as $value) {  echo $value->region. " <br/> ";  echo $value->city." <br/> ";  echo $value->ip." <br/> "; } ?>   /or access to echo $res 1->data->city;    with Object data
