преобразовать этот формат массива в один массив в php

Question

Я хочу преобразовать этот массив в одномерный плоский массив без потери порядка сортировки.

 
Array 
(
    [0] => Array 
     (
      [id] => 1 
      [title] => Computer 
      [parent_id] => 0 
      [children] => Array 
       (
        [0] => Array 
         (
          [id] => 4 
          [title] => keyboard 
          [parent_id] => 1 
          [children] => Array 
           (
            [0] => Array 
             (
              [id] => 6 
              [title] => Mouse 
              [parent_id] => 4 
              [children] => Array 
               (
                [0] => Array 
                 (
                  [id] => 7 
                  [title] => webcam 
                  [parent_id] => 6 
                 )

Дайте ему попробовать с функциями, указанными ниже:

function makeOneDimensionArray(array $array, &$res = array()) 
{ 
    foreach($array as $arr) 
    { 
     $res[] = array(
      'id' => $arr['id'], 
      'title' => $arr['title'], 
      'parent_id' => $arr['parent_id'] 
     ); 
     if(isset($arr['children'])) 
     { 
      makeOneDimensionArray($arr['children'], $res); 
     } 
    } 
    return $res; 
} 

$finalArr = makeOneDimensionArray($your_array); 
print_r($finalArr);
