I have an array in php with Objects containing an id and a parent_id. All Objects without a parent_id should be the root Objects in a new array.

do bir parent_id tüm nesneler doğru nesnesinin çocukları dizide itti olmalıdır:

So this is my original array:

array
  0 => 
    object(Node)[528]
      protected 'id' => int 1
      protected 'parent_id' => null
  1 =>
   object(Node)[529]
      protected 'id' => int 2
      protected 'parent_id' => null
  2 => 
   object(Node)[530]
      protected 'id' => int 3
      protected 'parent_id' => 1
  3 =>  
   object(Node)[531]
      protected 'id' => int 4
      protected 'parent_id' => 1
  4 =>  
  object(Node)[532]
      protected 'id' => int 5
      protected 'parent_id' => 4
  5 =>  
  object(Node)[533]
      protected 'id' => int 6
      protected 'parent_id' => 4

this is what the new array should look like:

$nodes = array(
  array(
   'id' => 1,
   'parent_id' => null,
   'children' => array(
    array(
     'id' => 3,
     'parent_id' => 1,
     'children' => null
    ),
    array(
     'id' => 4,
     'parent_id' => 1,
     'children' => array(
      array(
       'id' => 5,
       'parent_id' => 4
      ),
      array(
       'id' => 6,
       'parent_id' => 5
      ), 
     )
    ),
   ),
  ),
  array(
   'id' => 2,
   'parent_id' => null,
   'children' => null
  ),
 );

Bunu nasıl Herhangi bir fikir?
