php - PHP 在递归函数中追加数组 [0] 以获取未知深度

问题描述

我有已转换为数组的 xml。响应数组似乎没有为一个结果创建数组 [0]，而是为许多结果创建数组 [0]、[1]、[2]。所以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 - 许多细节

(
    [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：

每个节点可以有一个或多个子节点，所以我想为每个节点制作 [0]，为多个子节点制作 [0][1][2]etc。我尝试了一些代码并且在维护当前数组结果以添加递归函数时遇到问题。我是否需要函数外部变量来存储我当前的数组，或者在调用递归函数时附加它。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 的结果将仅在 [BookedDetail] 下创建 [0] 节点，因为我还没有调用递归函数。我需要帮助才能获得预期的数组结果。非常感谢你的帮助。

你可以尝试这样的事情，但我怀疑 array_merge 在这种情况下是否有效。您需要创建数组以向其添加多个值。在这一行中，您需要一个数组 $arr1[$arrkey][$subkey][] 来保存多个值

$x1 = json_decode(json_encode($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);
