Reverse Number

This algorithm reverse the given number. For example if given number is 123 then output number will be 321.

									function Reverse($num)
{
	$reverse = 0;

	while ($num != 0)
	{
		$reverse *= 10;
		$reverse += $num % 10;
		$num = (int)($num / 10);
	}

	return $reverse;
}

Example

									$rev = Reverse(1234);
