You can echo + sign if your total is greater than 0: echo ($total > 0 ? '+' : '').$total;

$total = 2;
echo ($total > 0 ? '+' : '').$total; // +2

$total = 0;
echo ($total > 0 ? '+' : '').$total; // 0

$total = -1;
echo ($total > 0 ? '+' : '').$total; // -1

You can use a helper function as following:

function getPositiveOrNegative($number){
  return ($number >= 0) ? '+' : '';
}

$number = 10;
echo getPositiveOrNegative($number).$number.'<br/>';

$number = -20;
echo getPositiveOrNegative($number).$number.'<br/>';

$number = 0;
echo getPositiveOrNegative($number).$number.'<br/>';

Output:
+10
-20
+0
