阿里云的api获取了结果后 如何使用？【小白问题】

[「已注销」]

<?php
    $host = "https://dm-81.data.aliyun.com";
    $path = "/rest/160601/ip/getIpInfo.json";
    $method = "GET";
    $appcode = "08b0400dd5e9477c88ec46******a019ff911c";
    $headers = array();
    array_push($headers, "Authorization:APPCODE " . $appcode);
    $querys = "ip=122.224.6.2";
    $bodys = "";
    $url = $host . $path . "?" . $querys;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_FAILONERROR, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_HEADER, true);
    
    if (1 == strpos("$".$host, "https://"))
    {
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    }
    
    var_dump(curl_exec($curl));

?>

以上是调用阿里云的api--获取ip地址的归属地，其中为了安全，我把appcode 已经隐藏了。

以上代码获取的结果如下：

{"code":0,"data":{"area":"华东","area_id":"300000","city":"绍兴市","city_id":"330600","country":"中国","country_id":"CN","county":"","county_id":"","ip":"122.224.6.2","isp":"电信","isp_id":"100017","region":"浙江省","region_id":"330000"}}' (length=1066)

请问我如何调用json中具体的字段啊，我只想获取 浙江省、绍兴市 然后赋予变量 再显示出来？求高手指点，我是菜鸟。

引用 3 楼 xuzuning 的回复:

curl_setopt($curl, CURLOPT_HEADER, false); //不返回 http 头 $json = curl_exec($curl); //获取返回的 json $data = json_decode($json, true); // 将返回的 json 解码成数组 print_r($data); // 看一下 难道你连访问数组成员都不会？！

谢谢版主，已经搞定了， 数组成员访问我会，呵呵

解码后直接按键名获取

版主可以给个代码吗？我自己写的出不来效果。谢谢
