php太多if else声明

Question

I have php code as below:

if($ptp_car_1 == "ptp_Denpasar_Ubud_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Ubud_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Tanah_Lot_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Tanah_Lot_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Sanur_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Sanur_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Seminyak_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Seminyak_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Kuta_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Kuta_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Jimbaran_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Jimbaran_Denpasar_fee_".$way."_car_1";
    }
    if($ptp_car_1 == "ptp_Denpasar_Nusa_Dua_fee_".$way."_car_1"){
        $ptp_car_1 = "ptp_Nusa_Dua_Denpasar_fee_".$way."_car_1";
    }
// many code over 1,000

How can i optimize it ? I want the page run faster, now is too slow for it.

Answer 1

in this case, SWITCH CASE should be better.

go through this...

Why the switch statement and not if-else?

Is "else if" faster than "switch() case"?

give a try to this,

switch ($ptp_car_1){   
        case "ptp_Denpasar_Ubud_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Ubud_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Tanah_Lot_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Tanah_Lot_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Sanur_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Sanur_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Seminyak_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Seminyak_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Kuta_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Kuta_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Jimbaran_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Jimbaran_Denpasar_fee_".$way."_car_1";
        }
        break;
        case "ptp_Denpasar_Nusa_Dua_fee_".$way."_car_1":
        {
             $ptp_car_1 = "ptp_Nusa_Dua_Denpasar_fee_".$way."_car_1";
        }
        break;

        /*
        //OPTIONAL

        default:
            $ptp_car_1 = $ptp_car_1;

        */
