array_walk_recursive返回數組名稱而不是索引號

-2

有沒有辦法讓array_Walk_recursive返回數組的名稱而不是索引？array_walk_recursive返回數組名稱而不是索引號

function flatten(array $array) { 
    $return = array(); 
    array_walk_recursive($array, function($a) use (&$return) { $return[] = $a; }); 
    return $return; 
}

我的結果是這樣的

Array 
(
    [0] => 888 
    [1] => TY7452 
    [2] => 63214 
    [3] => 0 
    [4] => Upper 
)

我希望可以改變索引像第一個數組名應該是名稱，然後第二個應該是數量。另外一個問題是，我能夠推出這個名稱後，是否可以使用implode來設置數組名稱的路徑，這將替換我目前獲得的索引號？例如，car.model.number

我的數組

$trading = [ 
    'id' => 888, 
    'case_number' => 'KO2017-987', 
    'property' => [ 
     'id' => 78563, 
     'propertyType' => [ 
      'id' => 1, 
      'name' => 'Residential' 
     ], 
     'address' => [ 
      'block' => '85', 
      'street' => 'Jalan Serjana', 
      'subpremise' => '#07-05', 
      'building' => 'TM Block', 
      'country_code' => 'MY' 
     ], 
     'askingPrice' => '650000.00', 
     'photos' => [ 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/1k985k63-652b-4dpc-988b-b98f75364db0.jpg', 
       'is_default' => 1 
      ], 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/8cf78fb6-9545-4f5f-8dfc-235a57a2b8c1.jpg', 
       'is_default' => 0 
      ], 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/e456218f-8b22-4250-9b29-72c1d3f5dc45.jpg', 
       'is_default' => 0 
      ] 
     ] 
    ], 
];

所需的結果

陣列

(
    [id] => 888 
    [case_number] => KO2017-987 
    [property.id] => 78563

    [property.propertyType.name] => Residential 
    [property.address.block] => 85 
    [property.address.street] => Jalan Serjana 
    [property.address.subpremise] => #07-05 
    [property.address,building] => TM Block 
    [property.address.country_code] => MY 
    [property.askingPrice] => 6500000.00

你的問題真的很難了解。什麼是「數組名稱」？你可以舉一個你想傳遞給'flatten'的數組的例子和你想要的結果嗎？ – smarx

^輸入陣列和期望的輸出陣列所需 – 2016-08-22 04:43:58

好像這樣 [ $交易= [ 'ID'=>， 'CASE_NUMBER'=> 'TX2015-0123'， '屬性'=> [ ' id'=> 69134, 'propertyType'=> [ 'id'=> 1, 'name'=>'Residential' ] ] ]; –

試試這個：

function flatten(array $array, $prefix="") { 
    $result = Array(); 
    array_walk($array, function ($value, $key) use ($array, $prefix, &$result) { 
     $path = $prefix ? "$prefix.$key" : $key; 
     if (is_array($value)) { 
      $result = array_merge($result, flatten($value, $path)); 
     } else { 
      $result[$path] = $value; 
     } 
    }); 

    return $result; 
} 

$trading = [ 
    'id' => 888, 
    'case_number' => 'KO2017-987', 
    'property' => [ 
     'id' => 78563, 
     'propertyType' => [ 
      'id' => 1, 
      'name' => 'Residential' 
     ], 
     'address' => [ 
      'block' => '85', 
      'street' => 'Jalan Serjana', 
      'subpremise' => '#07-05', 
      'building' => 'TM Block', 
      'country_code' => 'MY' 
     ], 
     'askingPrice' => '650000.00', 
     'photos' => [ 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/1k985k63-652b-4dpc-988b-b98f75364db0.jpg', 
       'is_default' => 1 
      ], 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/8cf78fb6-9545-4f5f-8dfc-235a57a2b8c1.jpg', 
       'is_default' => 0 
      ], 
      [ 
       'url' => 'https://www.jokok.com/thumbnails/600x400F/e456218f-8b22-4250-9b29-72c1d3f5dc45.jpg', 
       'is_default' => 0 
      ] 
     ] 
    ], 
]; 

print_r(flatten($trading));
