Find Sum of Digits
In the following example, we will add all the digits in the given number (12345) for just one time.
For example, 12345 = 1 + 2 + 3 + 4 + 5
i.e., 12345 = 15
Example
PHP Compiler
<?php
$num = 12;
$copyNum = $num;
$total = 0;
// Add Each digit from last digit
while($copyNum != 0)
{
$total += $copyNum % 10;
$copyNum = floor($copyNum / 10);
}
// result
echo "Sum of digit of $num: $total";
?>
Output
Sum of digit of 12: 3
