In reference to the factorial function posted previously: A recursive solution is almost any time
worse than an iterative one. Plus, in this case it is easy to provide such a solution:
<?php
bcfact($x) {
$res = 1;
for ($i = $x; bccomp($i, '0') == 1; bcsub($i, '1')) {
$res = bcmul($res, $i);
}
return $res;
}
?>
