php 怎样把图一的数据 用程序写成图2省市区的格式 纠结好久 写不出来 求大神
有3种方法：
1、手工一行一行的写成php代码
2、使用程序分析图一的数据，写入到数据库里，然后动态查询
3、使用程序分析图一的数据，写入到数据库里，动态生成图二的代码

Q1: php怎么写出全国的城市地区？
require 'city.php';
// 连接数据库(PDO)
$pdo=new PDO('mysql:host=localhost;dbname=city','root','root');
$pdo-exec('set names utf8');
$pdo-setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE,PDO::FETCH_ASSOC);
// 实例化城市类
$c=new city();
$result=$c-mycity();
$city_id = 0;
foreach ($result as $k=$value) {
if(count($value) == count($value,1)){
$sql="insert into city_province (province) value ('{$value['province_name']}')";
$smt=$pdo-prepare($sql);
$smt-execute();
}else{
$sql11="insert into city_province (province) value ('{$value['province_name']}')";
$smt11=$pdo-prepare($sql11);
$smt11-execute();
foreach ($value['city'] as $v=$value1) {
$sql2="insert into city_name (name,province_id) values ('{$value1['city_name']}','{$k}')";
$smt2=$pdo-prepare($sql2);
$smt2-execute();
$city_id += 1;
echo $city_id.'br';
if(!empty($value1['area'])){
foreach ($value1['area'] as $valu1e2) {
$sql3="insert into city_area (area,city_id) values ('{$valu1e2}','{$city_id}')";
$smt3=$pdo-prepare($sql3);
$smt3-execute();
}
}
}
}
}
城市类太大了，发不了。
我是把省、市、地区分别存在三个数据表中（我是新手，刚自己写的）
