英文:
I have nth level of nested array with string naming key , I want to convert that in indexing key only for array of item key.
i tried it to convert but that conversation only possible for limited level of nested array rather than nth level .
Input array:
$input_array= [
"NOCPL-All -working" => [
"name" => "NOCPL-All -working",
"item" => [
"apis for web" => [
"name" => "apis for web",
"item" => [
"0" => [
"name" => "update user branch maps"
]
]
],
"update user web" => [
"name" => "update user web",
"item" => [
"0" => [
"name" => "update user"
],
"1" => [
"name" => "add user"
]
]
]
]
]
];
I tried below code to convert indexing of 'item' nested array for limited level
function cleanArrayKeys($arr) {
foreach($arr as $k=>$arr1) {
if(isset($arr[$k]['item'])) {
$arr[$k]['item'] = array_values($arr[$k]['item']);
foreach($arr[$k]['item'] as $k1=>$arr2) {
if(isset($arr[$k]['item'][$k1]['item'])) {
$arr[$k]['item'][$k1]['item'] = array_values($arr[$k]['item'][$k1]['item']);
foreach($arr[$k]['item'][$k1]['item'] as $k3=>$arr3) {
if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'])) {
$arr[$k]['item'][$k1]['item'][$k3]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item']);
foreach($arr[$k]['item'][$k1]['item'][$k3]['item'] as $k4=>$arr4) {
if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'])) {
$arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item']);
foreach($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'] as $k5=>$arr5) {
if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item'])) {
$arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item']);
}
}
}
}
}
}
}
}
}
}
return $arr;
}
print_r(cleanArrayKeys($input_array));
?>
Expected Output :
[
"NOCPL-All -working" => [
"name" => "NOCPL-All -working",
"item" => [
"0" => [
"name" => "apis for web",
"item" => [
"0" => [
"name" => "update user branch maps"
],
"1" => [
"name" => "add user branch maps"
]
]
],
"1" => [
"name" => "update user web",
"item" => [
"0" => [
"name" => "update user"
]
]
]
]
]
];

尝试使用递归：
function aValues(&$arr) {
if (array_key_exists('item', $arr)) {
$arr['item'] = array_values($arr['item']);
}
foreach ($arr['item'] as &$el) {
if (array_key_exists('item', $el)) {
aValues($el);
}
}
}
aValues($input_array);
print_r($input_array);
英文:
Try using a recursion:
function aValues(&$arr) {
if (array_key_exists('item', $arr)) {
$arr['item'] = array_values($arr['item']);
}
foreach ($arr['item'] as &$el) {
if (array_key_exists('item', $el)) {
aValues($el);
}
}
}
aValues($input_array);
print_r($input_array);
