Solution 2

The second return (return self::$door_count;) is never reached because the first one is the exit point.

Solution 1

PHP

static function car_detail(){
    return self::$wheel_count;
    return self::$door_count;
}

The first return statement is the one that exits the function, and returns the value 4. Please go to PHP: PHP Manual - Manual[^] and study the language.

Basically yes. In your code the second return statement can never be reached.
