1、首先登录百度帐号，创建一个新应用，选择WEB应用吧，设置下可访问的白名单

2、将获得的ak填入接口中，形如：

http://api.map.baidu.com/geocoder/v2/?ak=你的百度key&location=".$latitude.",".$longitude."&output=json&pois=1

3、运行接口，可得到返回的json串

具体代码如下：

$query = "SELECT * FROM store order by id desc";$row = mysql_query($query);$n = 1;while($rows = mysql_fetch_array($row)){    $longitude = $rows['longitude'];    $latitude = $rows['latitude'];    //调取百度接口,其中ak为百度帐号key,注意location纬度在前，经度在后    $api = "http://api.map.baidu.com/geocoder/v2/?ak=你的百度key&location=".$latitude.",".$longitude."&output=json&pois=1";    $content = file_get_contents($api);    $arr = json_decode($content,true);    $province = $arr['result']['addressComponent']['province'];    $city = $arr['result']['addressComponent']['city'];    $district = $arr['result']['addressComponent']['district'];    $sql = "UPDATE store set province='".$province."',city='".$city."',area='".$district."' where storeid=".$rows['storeid'];    $res = mysql_query($sql);    if($res){        echo '成功更新第'.$n.'个门店<br>';        $n++;    }else{        echo '失败';    }}
