Question

这是我的情景：

如果单位<= 100，则收取Rs 1卢比/单位
如果单位是＆gt; 100＆amp;＆amp; ＆lt; = 200然后充电Rs 2卢比/单位
如果单位是＆gt; 200＆amp;＆amp; ＆lt; = 300然后充电Rs 3卢比/单位

如果单位是＆gt; 300然后充电Rs 7卢比/单位

if($units > 100){
$bill = 100 * 1;
$remaining_units= $units  -100;

if($remaining_units > 100 ){
    $remaining_units= $remaining_units  -100;
    $bill = $bill +  (100* 2);
    if($remaining_units > 100 || $remaining_units < 100){
         $remaining_units= $remaining_units  -100;
        $bill = $bill +  (100* 3);

        if($remaining_units > 100 || $remaining_units < 100){

            $bill = $bill +  (100* 7);
        }
    }
}
}
echo $bill;

Answer 1

使用此功能此功能适用于您：

echo calculate_bill(210);

    function  calculate_bill($units, $multipler = 1, $oldBill=0){
        if($units > 100){
            $remainingUnits = $units -100;
            $oldBill = (100 * $multipler) + $oldBill;           
        }else{
             $a = ($units * $multipler) + ($oldBill);
             return $a;
        }
        /*first level complete*/            
        if($multipler == 1){ 
            $multipler = 2;
        }elseif($multipler == 2){
            $multipler = 3;
        }elseif($multipler >= 3){ 
            $multipler = 7;
        }
        return calculate_bill($remainingUnits,$multipler, $oldBill);        
    }

Answer 2

雅现在正常工作

if($units < 100){
        $bill = $units*1;
    }elseif($units > 100 && $units <=200){
        $temp = 100*1;
        $remaining_units = $units - 100;
        $bill = $temp + ($remaining_units *2);
    }elseif($units > 200 && $units <=300){
        $temp = (100*1)+ (100*2);
        $remaining_units = $units - 200;
        $bill = $temp + ($remaining_units *3);
    }else{
        $temp = (100*1)+ (100*2)+ (100*3);
        $remaining_units = $units - 300;
        $bill = $temp + ($remaining_units *7);
    }

    echo $bill;

我想用php中的单位计算电费
