如何在PHP类中重新定义变量值并将其用于其他方法？

Question

I can't get value variable in a method, after use this value to another method in one class PHP Laravel.

public function paymentCourse(Request $request)
{

    $idCourse = $request->input('idcourse');
    $CoursePrice = Course::where('id', $idCourse)->first();

    if(Auth::user()->palate) {

        if(Auth::user()->palate->is_palate == 1) {
             // this value I want to transfer method getTransactionAmount()
            $currentPrice = $CoursePrice->price_palate;
        }

    } else {
         // this value I want to transfer method getTransactionAmount()
        $currentPrice = $CoursePrice->price;
    }

    return view('pages.payment-course', compact('currentPrice'));

}



public function getTransactionAmount($type) {

    switch ($type) {
        case 'palate':
            return 11645;
            break;
        case 'course':            
            return 15000; // I get value method paymentCourse() $currentPrice.
            break;
        case 'course_sale':                
            return 12000; // I get value method paymentCourse() $currentPrice.
            break;
        default:
            throw new \Exception('Wrong transaction type');
    }

}

This is my solution, thank you for help.

public function paymentCourse(Request $request)
{

    $idCourse = $request->input('idcourse');
    $CoursePrice = Course::where('id', $idCourse)->first();

    if(Auth::user()->palate) {

        if(Auth::user()->palate->is_palate == 1) {
            $currentPrice = $CoursePrice->price_palate;
            \Session::put('currentPrice', $currentPrice);
        }

    } else {
        $currentPrice = $CoursePrice->price;
        \Session::put('currentPrice', $currentPrice);
    }


    return view('pages.payment-course', compact('currentPrice'));

}

private function getTransactionAmount($type) {

    $currentPrice = \Session::get('currentPrice');

    switch ($type) {
        case 'palate':
            return 11645;
            break;
        case 'course':
            return $currentPrice;
            break;
        case 'course_sale':
            return $currentPrice;
            break;
        default:
            throw new \Exception('Wrong transaction type');
    }

}
