具有溢出整数的PHP模数

I get integer overflow value 7.233907357909E+16 from multiplication.

Now i need to calculate modulus 7.233907357909E+16 % 15.

How can i solve it, any idea how to do this?

You should look into bcmul and bcmod for arbitrary precision computations.

Example:

$res = bcmul('134334244395933282', '2834783723423487283');
$modRes = bcmod($res, '15');
echo $modRes;
