  Probably because the maximum signed 32 bit integer value is
  2,147,483,648


OK, but with bigger numbers works fine again.
Right now I made a function to deal with this issue:

function remainder($dividend,$divisor){
$remainder= $dividend-(floor($dividend/$divisor)*$divisor);
return $remainder;
}

What do you think about it?

  if you are dealing with numbers that large, consider using some arbitrary
 precision math functions that can work with as large of numbers as you need.
