[PHP追加数组[0]在未知深度的递归函数中]]

Question

我有已转换为数组的xml。响应数组似乎不是为一个结果创建array [0]，而是为许多结果创建array [0]，[1]，[2]。因此，我想为每个结果响应创建array [0]以便标准化我的迭代。初始响应数组如下：

数组-一个细节

(
   [BookedDetail] => Array
        (
            [BookedDetailID] => 192            
            [Customer] => Array
                (
                    [CustomerID] => 110
                    [LanguageID] => 2                    
                    [Address] => Array
                        (
                            [StreetName] => Northway 23
                            [PostalCode] => 29843
                            [Region] => NSW
                        )
                )
            [Currency] => Array
                (
                    [CurrencyID] => 19
                    [CurrencyName] => Yen
                    [CurrencyShortName] => JPY 
                )
            [Status] => 1
            [CreateBy] => 15
        )
)
数组-许多详细信息

(
    [BookedDetail] => Array
        (
            [0] => Array
            (
                [BookedDetailID] => 192            
                [Customer] => Array
                    (
                        [CustomerID] => 110
                        [LanguageID] => 2
                        [CustomerType] => 1
                        [Address] => Array
                            (
                                [StreetName] => Northway 23
                                [PostalCode] => 29843
                                [Region] => NSW
                            )
                    )
                [Currency] => Array
                    (
                        [CurrencyID] => 19
                        [CurrencyName] => Yen
                        [CurrencyShortName] => JPY 
                    )
                [Status] => 3
                [CreateBy] => 16
            )
            [1] => Array
            (
                [BookedDetailID] => 193            
                [Customer] => Array
                    (
                        [CustomerID] => 113
                        [LanguageID] => 2
                        [CustomerType] => 1
                        [Address] => Array
                            (
                                [StreetName] => Southway 23
                                [PostalCode] => 2852
                                [Region] => SSW
                            )
                    )
                [Currency] => Array
                    (
                        [CurrencyID] => 23
                        [CurrencyName] => US Dollar
                        [CurrencyShortName] => USD
                    )
                [Status] => 2
                [CreateBy] => 17
            )
        )
)
我的预期结果：

(
    [BookedDetail] => Array
        (
            [0] => Array
            (
                [BookedDetailID] => 192            
                [Customer] => Array
                    (
                        [0] => Array
                        (
                            [CustomerID] => 110
                            [LanguageID] => 2
                            [CustomerType] => 1

                                    )
                                )
                        )
                    )
                [Currency] => Array
                    (
                        [0] = Array

                        [0] => Array
                        (
                            [CustomerID] => 113
                            [LanguageID] => 2
                            [CustomerType] => 1
                            [Address] => Array
                                (

                                        [PostalCode] => 2852
                                        [Region] => SSW
                                    )
                                )
                        )
                    )
                [Currency] => Array
                    (
                        [0] => Array

每个节点可以有一个或多个子节点，因此我想为每个节点设置[0]，为多个子节点设置[0] [1] [2]等。我尝试了一些代码，并在维护当前数组结果时遇到问题，以便添加递归函数。我是否需要外部变量来存储当前数组，还是在调用递归函数时追加它。我当前的代码：

$x1 = json_decode(json_encode($xmlobj), true);
$result = array();
function callarr ($arrin)
{            
    foreach ($arrin as $arrkey => $arrvalue)
    {
        foreach ($arrvalue as $subkey => $subvalue)
        {
            if (is_array($subvalue))
            {                               
                $arr1[$arrkey][$subkey] = $subvalue;               
                // recursive function here
            }
            else
            {
                $arr2[$arrkey][0][$subkey] = $subvalue;
            }
        }
        $result = array_merge($arr1, $arr2);                
    }
    return $result;   
}
$x2 = callarr ($x1);
print_r ($x2);
$ x2的结果只会在[BookedDetail]下创建[0]节点，因为我还没有调用递归函数。我需要帮助以获得预期的数组结果。非常感谢您的帮助。

我有已转换为数组的xml。响应数组似乎不是为一个结果创建array [0]，而是为许多结果创建array [0]，[1]，[2]。所以我想为每个一个创建array [0] ...

Answer 1

您可以尝试类似的方法，但是我怀疑array_merge在这种情况下是否可以工作。您需要创建数组以向其中添加多个值。如这一行所示，您需要一个数组$ arr1 [$ arrkey] [$ subkey] []来保存多个值

Answer 2

很难知道这是否正是您所追求的，但是您可能比我更容易检查它。
