PHP 在递归函数中附加数组[0]以获得未知深度

Question

我有已经转换为数组的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]，以便为我的迭代进行标准化。初始响应数组如下：

阵列 - 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
)
)

阵列 - 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：

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

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]等。我尝试了一些代码，但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的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);

$x 2 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。我需要帮助才能获得预期的数组结果。非常感谢您的帮助。

Answer 1

很难知道这是否正是你所追求的，但你可能比我更容易检查它。

该函数现在是递归的，您可以看到您的注释已被删除的位置，并且通过再次使用$arrvalue调用此函数来替换赋值......

function callarr ($arrin)
{
$result = array();
foreach ($arrin as $arrkey => $arrvalue)
{
if (is_array($arrvalue))
{
$result[$arrkey][] = callarr($arrvalue);
}
else
{
$result[$arrkey] = $arrvalue;
}
}
return $result;
}

Answer 2

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。 如在这一行中，您需要一个数组 $arr 1[$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);
