百度地图web服务API接口实现IP到简要地址的转化

百度地图ak参数配置

$CONF = array(
  "ak" => "11Z8uiP8kIz6AG0Vjiwzb**"
);

封装IP接口API

function getIp($ip, $ak)
{
  $url = "http://api.map.baidu.com/location/ip?ak=" . $ak . "&ip=" . $ip . "&coor=bd09ll";
  $res = file_get_contents($url);
  $b   = json_decode($res, true);
  //echo "<pre>";
  //var_dump($b);
  return $b["content"]["address"];
}

调用IP接口API

echo getIp("39.185.200.145", $CONF["ak"]);

Done！
