谁能帮助我用更好的方法代替这个代码片段，而不使用if elseif - can anyone help me to replace this code snippet with better approach without using if elseif

can anyone help me to replace this code snippet with better approach without using if elseif

在这个代码片段中，所有的值都是数据库驱动的，我需要一个更好的替代这个代码。

佣金的百分比将根据任务价格范围计算。

$commission1=10;//in percentage
     $commission2=20;
     $commission3=30;
     $taskprice =200;
     if($taskprice >=0 && $taskprice <=150)
       {
    $adminearnings = ($taskprice *$commission1 ) / 100 ;
    $Geniepayment = $taskprice - $adminearnings;
       }
    else if($taskprice >=151 && $taskprice <=300)
      {
     $adminearnings = ($taskprice * $commission2) / 100 ;
     $Geniepayment = $taskprice - $adminearnings;
      }
   else if($taskprice >=301 && $taskprice <=450)
     {
    $adminearnings = ($taskprice * $commission3 ) / 100 ;
    $Geniepayment = $taskprice - $adminearnings;
     }
 echo $taskprice.'</br>';
 echo $adminearnings.'</br>';
 echo $Geniepayment.'</br>';

对于我来说，我会做一个简单的函数来快速访问您需要的内容:

function calculate($commission, $taskprice)
{
    $arrayCommission = array(0, 10, 20, 30);
    $adminearnings = ($taskprice * $arrayCommission[$commission] ) / 100 ;
    $Geniepayment = $taskprice - $adminearnings;
    return array($taskprice, $adminearnings, $Geniepayment);
}

就像这样:

if($taskprice >=0 && $taskprice <=150)
{
   $arrayAnswer = calculate(1, $taskprice);
}
elseif($taskprice >=151 && $taskprice <=300)
{
   $arrayAnswer = calculate(2, $taskprice);
}
elseif($taskprice >=301 && $taskprice <=450)
{
   $arrayAnswer = calculate(3, $taskprice);
}

我同意其他人认为条件是必需的。我将重构以提取计算结果，如下所示:

<?php
// Returns array(earnings, payment)
//
function getEarningsPayment($taskprice, $commission)
{
    $earnings = ($taskprice * $commission) / 100 ;
    $payment = $taskprice - $adminearnings;
    return array ($earnings, $payment);
}

$commission1=10;//in percentage
$commission2=20;
$commission3=30;
$taskprice =200;
if($taskprice >=0 && $taskprice <=150)
    $commission = $commission1;
else if($taskprice >=151 && $taskprice <=300)
    $commission = $commission2;
else if($taskprice >=301 && $taskprice <=450)
    $commission = $commission3;
list ($adminearnings, $Geniepayment) = getEarningsPayment($taskprice, $commission);
echo $taskprice.'</br>';
echo $adminearnings.'</br>';
echo $Geniepayment.'</br>';
?>

伙计们，这个主意怎么样?等待您的反馈和建议

    }
    }
    check_commission(200,$commissions);
