php 高德地图 地址转换经纬度

通过前端增加数据，选择的三级联动，转换为经纬度，插入到数据库，千万在插入之前转好，读取的时候方便，

控制器

$province=input('province');  //省
$city=input('city');    //市
$area=input('area');  //区
$address=$province.'省'.$city.$area;  //拼接一起    

    $resul=array();

    //分别把地址付给$address;
    $url = "https://restapi.amap.com/v3/geocode/geo?address=$address&output=JSON&&key=78b031d5358ca2da6dca52c013aac534";

    curl_close($ch);
    $result = json_decode($data, true);
