Sum of Digits

To find sum of digits of a number just add all the digits.

For example,

14597 = 1 + 4 + 5 + 9 + 7
14597 = 26

Logic:

Take the number.
Divide the number by 10.
Add the remainder to a variable.
Repeat the process until remainder is 0.

Example:

Given program shows the sum of digits of 14597.

<?php
$num = 14597;
$sum=0; $rem=0;
  for ($i =0; $i<=strlen($num);$i++)
 {
  $rem=$num%10;
   $sum = $sum + $rem;
   $num=$num/10;
  }
 echo "Sum of digits 14597 is $sum";
 ?>
