[Anon]

Hi all,

I have got a number like 89 or anything, And I want to count it like 8+9 =17 and then if it is more than 9 then count it again ..like 1+7=8

So my problem is I am unable to get any function which reads each charactor in a string or integer..

Can anybody help me ??

try accessing the individual characters using the {} syntax:

$str="12";

$total=$str{0}+$str{1};

$total will equal 3;

$sum = substr($var, 0,1) + substr($var, 1,1);
