Integer (64-bit) division of large numbers without using intdiv() (before php7)

Question

Tests are made at 64-bit system!

php7 has a nice function: intdiv(). The following code works perfect:

$number = 0x7fffffffffffffff;
$result         


        

Answer 1

You can use the % operator to get the remainder. Then after subtraction of the remainder perform the division:

$rem = $number % 62;
$result = ($number - $rem) / 62;
