我如何高效地在php中編寫查找表？

我正在嘗試編寫一個函數，用於查找汽車上保險支付的$InterestRate值。我已經插入的代碼見下表：我如何高效地在php中編寫查找表？

目前我曾嘗試：

function interestRate() { 
if ((int)$VehicleYear >= 2001) && (int)$VehicleYear <= 2005){ 

    $Term = 24; 

    if ((int)$CreditScore >= 720){ 
     $InterestRate = 15.90; 
    } 
    elseif ((int)$CreditScore >= 610) || ((int)$CreditScore <= 719) { 
     $InterestRate = 19.90; 
    } 
    elseif ((int)$CreditScore >= 580) || ((int)$CreditScore <= 609) { 
     $InterestRate = 22.90; 
    } 
    elseif ((int)$CreditScore >= 530) || ((int)$CreditScore <= 579) { 
     $InterestRate = 22.90; 
    } 
    elseif ((int)$CreditScore >= 489) || ((int)$CreditScore <= 529) { 
     $InterestRate = 22.90; 
    } 
} 

if ((int)$VehicleYear == 2006){ 

    $Term = 24; 

    if ((int)$CreditScore >= 720){ 
     $InterestRate = 15.90; 
    } 
    elseif ((int)$CreditScore >= 610) || ((int)$CreditScore <= 719) { 
     $InterestRate = 18.90; 
    } 
    elseif ((int)$CreditScore >= 580) || ((int)$CreditScore <= 609) { 
     $InterestRate = 21.90; 
    }

     $InterestRate = 18.90; 
    } 
} 
}

它既是乏味的，只是當我嘗試在計算中使用$InterestRate不起作用。解決這個問題的最好方法是什麼？

無論你傳遞'$ ssn'和'$ VehicleYear'值到這個函數，你也不會使用'global'。你是如何在函數內獲得這個'$ ssn'和'$ VehicleYear'的值的？ –

哦對不起，讓我解決這個問題 – Tendi

在這裏你去：所有重複的代碼被刪除：

function creditScore($cs) { 
    $cs = (int) $cs; 

    if  ($cs >= 720)    return 5; 
    elseif ($cs >= 610 && $cs <= 719) return 4; 
    elseif ($cs >= 580 && $cs <= 609) return 3; 
    elseif ($cs >= 530 && $cs <= 579) return 2; 
    elseif ($cs >= 489 && $cs <= 529) return 1; 
    else        return 0; 
} 

function interestRate($vehicleYear, $creditScore) { 
    $vehicleYear = (int) $vehicleYear; 
    $cred = creditScore($creditScore); 
    if (! $cred)  // handle credit score below 489: returns 0 
     throw new Exception("Unsupported creditScore: $creditScore"); 
    $cred--; // otherwise it's 1..5, change to 0..4 for array index 

    $rates = [ 
     2001 => [ 'term' => 24, 'rates' => [ 22.90, 22.90, 22.90, 19.90, 15.90 ] ],

    return [ // TODO: check if isset($rates[$vehicleYear ]) 
     $rates[$vehicleYear]['rates'][ $cred ], 
     $rates[$vehicleYear]['term']

list($interestRate, $term) = interestRate(2013, 666);

我不確定這是如何實際工作的，以及如何使用它。順便提一下，我正在用適當的變量更新問題。 – Tendi

好吧，我會解釋這一點，以及如何在查詢表中不使用SQL。幾分鐘。 – Kenney

我創建了一個表並將其放在問題的詳細信息中，以查看我正在處理的問題 – Tendi

我如何高效地在php中編寫查找表？
