Example #1 Factorial function using GMP


<?php

function fact($x) 

{

    $return = 1;

    for ($i=2; $i < $x; $i++) {

        $return = gmp_mul($return, $i);

    }

    return $return;

}



echo gmp_strval(fact(1000)) . "\n";

?>

This will calculate factorial of 1000 (pretty big number) very fast.
