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:

  1. $input_array= [
  2.     "NOCPL-All -working" => [
  3.             "name" => "NOCPL-All -working",
  4.             "item" => [
  5.                         "apis for web" => [ 
  6.                             "name" => "apis for web",
  7.                             "item" => [
  8.                                     "0" => [
  9.                                             "name" => "update user branch maps"
  10.                                         ]
  11.                             ]
  12.                         ],
  13.                         "update user web" => [ 
  14.                             "name" => "update user web",
  15.                             "item" => [
  16.                                     "0" => [
  17.                                             "name" => "update user"
  18.                                         ],
  19.                                         "1" => [
  20.                                             "name" => "add  user"
  21.                                         ]
  22.                             ]
  23.                         ]
  24.                     ]
  25.                 ]
  26.             ];

I tried below code to convert indexing of 'item' nested array for limited level

  1. function cleanArrayKeys($arr) {
  2.         foreach($arr as $k=>$arr1) {
  3.             if(isset($arr[$k]['item'])) {
  4.                 $arr[$k]['item'] = array_values($arr[$k]['item']);
  5.                 
  6.                 foreach($arr[$k]['item'] as $k1=>$arr2) {
  7.                     if(isset($arr[$k]['item'][$k1]['item'])) {
  8.                         $arr[$k]['item'][$k1]['item'] = array_values($arr[$k]['item'][$k1]['item']);
  9.                         
  10.                         foreach($arr[$k]['item'][$k1]['item'] as $k3=>$arr3) {
  11.                             if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'])) {
  12.                                 $arr[$k]['item'][$k1]['item'][$k3]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item']);
  13.                                 
  14.                                 foreach($arr[$k]['item'][$k1]['item'][$k3]['item'] as $k4=>$arr4) {
  15.                                     if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'])) {
  16.                                         $arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item']);
  17.                                         
  18.                                         foreach($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'] as $k5=>$arr5) {
  19.                                             if(isset($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item'])) {
  20.                                                 $arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item'] = array_values($arr[$k]['item'][$k1]['item'][$k3]['item'][$k4]['item'][$k5]['item']);
  21.                                             }
  22.                                         }
  23.                                 
  24.                                     }
  25.                                 }
  26.                             }
  27.                         }
  28.                 
  29.                     }
  30.                 }
  31.             }
  32.         }
  33.         
  34.         return $arr;
  35.     }
  37. print_r(cleanArrayKeys($input_array));
  38. ?>

Expected Output :

  1. [

  8.                                     "0" => [
  9.                                             "name" => "update user branch maps"
  10.                                         ],
  11.                                         "1" => [
  12.                                             "name" => "add  user branch maps"
  13.                                         ]

  23.                         ]
  24.                     ]
  25.                 ]
  26.             ];

得分: 1

尝试使用递归：

  1. function aValues(&$arr) {
  2.     if (array_key_exists('item', $arr)) {
  3.         $arr['item'] = array_values($arr['item']);
  4.     } 
  6.     foreach ($arr['item'] as &$el) {
  7.         if (array_key_exists('item', $el)) {
  8.             aValues($el);
  9.         }
  10.     }
  11. }
  13. aValues($input_array);
  15. print_r($input_array);
