Hello my goal is to add the same values ​​in an array and remove the repeated values ​​then add the sum of these repeated values ​​in the same array in a repetitive way until all the elements of the array will be distinct.
I made this code but it does it just once, how to repeat this action several times until the good result? thanks

function magic($arr)

{



    $result = array_filter(array_count_values($arr), function ($el) {

        return $el > 1;

    });

    foreach ($result as $k => $val) {

        $a[] = $k;

        $b[] = $k * $val;

    }



    $c[] = array_merge(array_diff($arr, $a), $b);



    return $c;

}





print_r(magic([5, 5, 8, 8, 10, 9,20, 7, 7]));//found:[10,9,20,10,16,14]  excpected:[9,40,14,16]( stape to find  result:[10,9,20,10,16,14]==>[20,9,20,16,14]==>[9,40,14,16])
