PHP only long no long long

If you need to do mathematical calculations, anti-Japanese righteousness using BC or GMP high-precision mathematical function extension

Can you specify how to use it? I want to calculate a value of 13353715570921140386 3

echo bcmod (' 13353715570921140386 ', 3); Out 2

You verify that, I'm right.
$s = ' 13353715570921140386 ';
$n = Array_sum (Str_split ($s));
echo $n% 3; Out 2
