我有一個像這樣的多維數組輸出： Array( [0] => Array ( [item] => null [count] => 0 [child] => Array ( [Dagadu Bocah] => Array ( [item] => Dagadu Bocah [count] => 47 [child] => Array ( [HirukPikuk] => Array ( [item] => HirukPikuk [count] => 5 [child] => Array ( [DGD] => Array ( [item] => DGD [count] => 1 [child] => ) ) )在我的期望中，我可以使用unsetforeach 循環中的函數來刪除每個具有 3 個鍵的數組，即“item”、“count”和“child”，以便它生成一個如下所示的數組： Array( [0] => ([Dagadu Bocah] =>Array([HirukPikuk] =>Array([DGD]) }}誰能幫忙？

對于您想要使用recursion的那種數據，如下所示：
<?php
function getChildKey(array $data)
{
$result = [];
if (isset($data['child'])) {
foreach ($data['child'] as $key => $value) {
$result[$key] = getChildKey($value);
}
}
if (empty($result)) {
return '';
}
return $result;
}
$input = [
[
'item' => null,
'count' => 0,
'child' => [
'Dagadu Bocah' => [
'item' => 'Dagadu Bocah',
'count' => 47,
'child' => [
'HirukPikuk' => [
'item' => 'HirukPikuk',
'count' => 5,
'child' => [
'DGD' => [
'item' => 'DGD',
'count' => 1,
'child' => null,
],
],
],
],
],
],
],
];
$output = [];
print_r($input);
foreach ($input as $index => $child) {
$output[$index] = getChildKey($child);
}
print_r($output);
