        // Not so nice.

        function foo($bar)

            if ($bar > 0) {
                return "YES";
            } else if ($bar == 0) {
                return "MAYBE"
            } else {
                return "NO";
            }
        }


        // Not so nice as well.

        function foo($bar)
        {
            $value = '';            

            if ($bar > 0) {
                $value = "YES";
            } else if ($bar == 0) {
                $value = "MAYBE"
            } else {
                $value = "NO";
            }

            return $value;
        }

        // Very much nice, yes, yes, sexy.

        function foo($bar) 
        {
            if ($bar > 0) {
                return "YES";
