利用高德API获取最新的省市区数据

直接上代码，只是保存数据，所以实现功能即可，代码有点乱

$key = 'xxxxx';//自己去高德申请即可
$url = 'https://restapi.amap.com/v3/config/district?subdistrict=3&key='.$key;
$res = file_get_contents($url);

$res = json_decode($res,true);//转换数组

$str = 'insert into fa_area values';//插入数据库
//        $data = [];
foreach ($res['districts'] as $v) {
    //循环一次
    $str .= "(null,".$v['adcode'].",'".$v['name']."',0,0), ";
    foreach ($v['districts'] as $vv) {
        //循环34次
        $str .= "(null,".$vv['adcode'].",'".$vv['name']."',1,".$v['adcode']."), ";
        foreach ($vv['districts'] as $vvv) {

            $str .= "(null,".$vvv['adcode'].",'".$vvv['name']."',2,".$vv['adcode']."), ";
            //循环市
//                    $temp_3[$vvv['adcode']] = [];
//                    $temp_4 = [];
            foreach ($vvv['districts'] as $kkkk=>$vvvv) {
                //循环区县
//                        $temp_4[$vvvv['adcode']] = $vvvv['name'];
                $code = $vvvv['adcode'];
                $str .= "(null,$code,'".$vvvv['name']."',3,".$vvv['adcode']."), ";
            }
//                    ksort($temp_4);
//                    $temp_3[$vvv['adcode']][] = $temp_4;
        }
//                ksort($temp_3);
//                $data[] = $temp_3;
    }
}
$str = rtrim($str, ', ');//删除最后一个空格
//        echo $str;
Db::name('area')->query($str);
die;
//        file_put_contents('area.txt',json_encode($data));//写入文件

这是fa_area表结构

CREATE TABLE `fa_area` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `code` int(10) NOT NULL,
  `name` varchar(50) NOT NULL,
  `level` tinyint(1) unsigned NOT NULL COMMENT '层级0-3',
  `pid` int(10) unsigned DEFAULT NULL COMMENT '上级code',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3725 DEFAULT CHARSET=utf8mb4 COMMENT='省市区';

这里需要注意的地方，就是有些市下面直接就是乡镇了，比如河南省济源市，所以需要注意这种数据的处理，切勿直接将adcode当做id，否则会重复
