解码嵌套JSON PHP

我想获得网站的域名、dns、ip地址等数据，我发现以下JSON结构可以帮助我做到这一点。 但我在解析特定信息时出错，例如dns_记录->类型、dns_记录->目标等。

以下是我的嵌套JSON代码：

如何从上述代码中找到

dns\u记录->类型

和

dns\u记录->目标

$record = '{

      "owner_email": null,

      "registrar_slug": "godaddy.com-llc",
      "hosted_ip": "66.135.33.172",

      "hosted_ip_full_country": "United States"
    }
  }
}';


$record = json_decode($record, true);

$dnsRecords = json_decode($record['data']['tutorialspoint.com']['dns_records'], true);

$typeArray = array();
$targetArray = array();
 foreach($dnsRecords as $row){
    foreach($row as $key=>$res){
        if($key == 'type'){
            $typeArray[] = $res;
        }
        if($key == 'target'){
            $targetArray[] = $res;
        }
    }
}

// targets
foreach($targetArray as $target){
    echo $target;
}

// types
foreach($typeArray as $type){
    echo $type;
}

我为目标和类型创建了两个数组，您可以通过这种方式访问每个

target

和

type

我想你需要这样的东西：

 $final_array= json_decode($array) 
    foreach ($final_arrayas $key => $value) {
            if ($key == 'data') {
                foreach ($value as $key2 => $val) {
                    foreach($val as $key3=> $child_array_val){
                   if($key3=='dns_records') echo "<pre>";
                    print_r($child_array_val);}
                }
            }
        }

$final\u array=json\u decode（$array）
foreach（$final_arrayas$key=>$value）{
如果（$key=='data'）{
foreach（$key2=>$val的值）{
foreach（$valas$key3=>$child\u array\u val）{
如果（$key3=='dns_记录'）回显“”；
打印（$child\u array\u val）；}
}
}
}

首先通过$final\u array=json\u decode（$array）将其转换为php数组，然后通过foreach循环获取元素，希望它能正常工作。为什么会有人在JSON中编码为JSON？您需要做的是

json\u解码（$var->dns\u记录）

@HassanTahir，我已经完成了json解码的一部分，但是我无法编写

foreach

循环的确切语法
