任何人都可以帮助我用更好的方法替换此代码片段，而无需使用ifif

Question

在此代码段中，所有值都将由数据库驱动，我需要更好地替换此代码。

佣金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>'; 

Answer 1

家伙怎么样这个想法..waiting为您的反馈和建议

$commissions = array 
    (
    '0'=>array 
    (
    "commission_start_range"=>"0","commission_end_range"=>"100","commission_amount"=>"10" 
), 
    '1'=>array 
    (
    "commission_start_range"=>"101","commission_end_range"=>"200","commission_amount"=>"20" 
), 
    '2'=>array 
    (
    "commission_start_range"=>"201","commission_end_range"=>"300","commission_amount"=>"30" 
) 
); 

function check_commission($task_price,$commissions) 
    { 
    foreach($commissions as $commission_data) 
    { 
    $start = $commission_data['commission_start_range']; 
    $end = $commission_data['commission_end_range']; 
    $amount= $commission_data['commission_amount']; 
    if($task_price >=$start && $task_price <=$end) 
    { 
    $admin_earnings = ($task_price * $amount)/100 ; 
    $genie_payment = $task_price - $admin_earnings; 
    return $admin_earnings;//echo $admin_earnings; 
    } 
    } 
    } 
    check_commission(200,$commissions); 

Answer 2

至于我，我会做一个简单的功能，有你所需要的快速访问：

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

这将是这样的：

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); 
} 

Answer 3

我同意其他条件是必需的。我将重构拔出计算，这样的事情：

<?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>'; 

?>
