 百度地图获取经纬度后，获取区域代码和地址：

function getdistrct_code($location){

 		$url ="api.map.baidu.com/geocoder/v2/?ak=jhPGtfGrTzyoMNBRi1PVtkODgfelXofF&output=json&pois=1";
      
        $post_msg =array(
            "location"=>$location
        );
        $ret_json =httpsPost($url, $post_msg);
        $res = json_decode($ret_json);
          $district = $res->result->addressComponent->adcode;
  	return $district;
}


function httpsPost($url, $data = null)
{
    $ch = curl_init();
    //curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $temp=curl_exec ($ch);
    curl_close ($ch);
    return $temp;
}

调用方法 : eg : http://api.map.baidu.com/geocoder/v2/?ak=jhPGtfGrTzyoMNBRi1PVtkODgfelXofF&output=json&pois=1&location=34.247986,108.716148

$location=$lat.','.$lng;
$district = getdistrct_code($location);

得到结果：
