I have array of the following  integer and a total value.

$total = 20;
$array = [1,2,3...];

can I add a $total value on array $array[0] to create a new value and then add the new value into array $array[1] to get new value and store that value into some variable that I can call later?

expected result:

$new_total1 = $total + $array[0]
$new_total2 = $new_total1 + $array[1]
and so on...
Answer :

code in PHP like :

$array = [1,2,3];
$total = 0;
$totals = [];
foreach($array as $index => $num){
    $total += $num;
    $totals[$index] = $total;
