Bug description:PHP function to clamp numbers

Description:
------------
Need a PHP function to clamp numbers, natively. Currently it is
possible, but will be great if it supports natively.

    function clamp($number, $minValue, $maxValue) {
        return max($minValue, min($maxValue, $number)); 
    }

Basically, it will return the $number if is greater than $minValue and
lower than $maxValue. If $number is lower than $minValue, it returns
$minValue. If $number is greater than $maxValue, it returns $maxValue.

    clamp(2, 1, 3); // => 2 (in range)
    clamp(1, 1, 3); // => 1 (in range, min value)
    clamp(3, 1, 3); // => 3 (in range, max value)
    clamp(0, 1, 3); // => 1 (out range, using min value)
    clamp(4, 1, 3); // => 4 (out range, using max value)
