Still too much typing ;) , try this:

$t = R('test',0,'int');

function R($k,$def = null,$type = null)
{
	if (!isset($_REQUEST[$k])) {
		return $def;
	}
	
	if (isset($type)) {
		return checktype($type,$_REQUEST[$k],$def);
	}
	
	return $_REQUEST[$k];
}

function checktype($type,$v,$def = null)
{
	switch ($type) {
		case 'int':
		case 'integer':
			if ((string)intval($v) !== strval($v)) {
				return $def;
			}
			return intval($v);
		case 'string':
			if (!is_string($v)) {
				return $def;
			}
			break;
	}
	
	return $v;
}

Mix up some additional flavors for $_GET, $_POST, etc and have some real
fun.
