Question

我有一个数组：-我正在从print_r函数获得此值。

问题是我想做的：在下面的输出中请帮忙：-

{
    "result": "SUCCESS",
    "records": [
                {
                    country : india,
                    states : [
                        {
                            state : karnataka
                            cities : [bangalore,mysore]
                        },
                        {
                            state : Tamilnadu
                            cities : [chennai,coimbutore]
                        }
                    ]
                },
                {
                    country : US,
                    states : [
                        {
                            state : ohiao
                            cities : [city 1,city 2]
                        },
                        {
                            state : california
                            cities : [city 1,city 2]
                        }
                    ]
                }
                ]
}

我尝试循环这个。

foreach ($returnData as $key => $value) {  
    $actual_response[$value['country']][$value['state']][]=$value['city'];
}

?>

您编写的代码不足以得到预期的响应。

Answer 2

您可以尝试将此代码放在数组下面并运行。

    function nested($item)
{
  if (count($item) > 1)
  {
    $key = array_shift($item);
    return array($key => nested($item));
  }
  else
  {
    return $item;
  }
}

$finalArr = array();

foreach($arr as $data)
{
  $finalArr = array_merge_recursive($finalArr, nested($data));
}


$finalArr = array_values($finalArr);
echo json_encode(array("result"=>"SUCCESS" ,"records"=>$finalArr) );exit;

我有一个数组
