Good mood to you all. Help the unfortunate to group such an array.

array(9) { [0]=> array(1) { ["level_1"]=> array(28) { [0]=> string(1) "8" ["id"]=> string(1) "8" [1]=> string(6) "Vka124" ["login"]=> string(6) "Vka124" [2]=> string(6) "Vka124" ["password"]=>

It is necessary that you can refer to the object by level_ for example, something like this

 echo $array["level_1"][0]["login"]

I have users in the array level_1 , level_2 and so on. So I need to group the array in such a way that I can pull information on the person who is in the array, for example, level_1

Thank you in advance for your help.

    If you consider that in your $array[$idx] can be only one level_X element, then the solution can be, for example, the following:

    Initial data:

     $data = [ 0 => [ "level_1" => ['login' => 'test-1-1']], 1 => [ "level_1" => ['login' => 'test-1-2']], 2 => [ "level_2" => ['login' => 'test-2-1']], ];

    Conversion:

     $result = []; foreach($data as $v){ $result[key($v)][] = current($v); } print_r($result);

    In this case, the key() and current() functions initially point to the first and only level_* element in the array.
    If for some reason you do not like using a loop, you can use the array_walk function to traverse the array, but this does not change the essence:

     $result2 = []; array_walk($data, function($v) use (&$result2){ $result2[key($v)][] = current($v);}); print_r($result2);
    • What you need, Thank you so much, that’s what you’ve felt today with this array. - Tokwiro
