PHP array_column - how to keep the keys?

Question

I'm having issues getting the key of $items using array_column.

This is the $items array:

$items = array(
    1 => [
        "id" => 5
    ],
    3 => [
        "id" => 6
    ],
    4 => [
        "id" => 7
    ],
);
    
var_dump(array_column($items,"id"));

Result:

array (size=3)
  0 => int 5
  1 => int 6
  2 => int 7

How can I get the desired result below?

array (size=3)
  1 => int 5
  3 => int 6
  4 => int 7

See if this could help

array_filter(array_combine(array_keys($items), array_column($items, 'id')));
