sum of number

[Pawan_Agarwal]

I want to add the number with this code

 

 

while($i>0)

{

$j=$i%10;

$i=$i/10;

$sum=$sum+$j;

}

 

I have number in $i=12345, now after execution, sum must return the sum of all digits of its number 15

 

Example:

$i=23, sum=5

$i=18, sum=9

$i=19, sum=10

 

As you can see the code must terminate as soon as $i==0, but I am facing infinite loop........thanks

Seems to work fine for me. One thing you could change is to ensure $i is an int.

 

$i=12345;
while($i>0)
{
  $j=$i%10;
  $i=intval($i/10);
  $sum=$sum+$j;
}

var_dump($sum);
