        }
    }
    
    public static function main()
    {
        $total = 6;
        echo "Fibonacci series of " . $total . " Elements  :";
        Fibonacci::fib($total, 0, 1);
        
        $total = 10;
        echo "\nFibonacci series of " . $total . " Elements :";
        Fibonacci::fib($total, 0, 1);
    }

Fibonacci::main();
