Question

如果用户输入：

$sgl = 2;
$dbl = 0;
$twn = 1;
$trp = 0;
$quad = 0;

$price_room = 250000;

我希望结果如下图所示：

我尝试这样的代码：

<?php
    $sgl = 2;
    $dbl = 0;
    $twn = 1;
    $trp = 0;
    $quad = 0;

    $price_room = 250000;

    $counter = 0;
    if($sgl>0){
        $counter++;
        $room_type = 'Single';
        $price = $price_room * 1;
    }

    if($dbl>0){
        $counter++;
        $room_type = 'Double';
        $price = $price_room * 2;
    }

    if($twn>0){
        $counter++;
        $room_type = 'Twin';
        $price = $price_room * 2;
    }

    if($trp>0){
        $counter++;
        $room_type = 'Triple';
        $price = $price_room * 3;
    }

    if($quad>0){
        $counter++;
        $room_type = 'Quad';
        $price = $price_room * 4;
    }


    // echo $counter;

?>

<table border="1">
    <tr>
        <td>No</td>
        <td>Room type</td>
        <td>Price</td>
    </tr>
<?php 
    $no=1;
    for($i=0;$i<$counter;$i++){
?>
    <tr>
        <td><?php echo $no; ?></td>
        <td><?php echo $room_type; ?></td>
        <td><?php echo $price; ?></td>
    </tr>
<?php
        $no++;
    }
?>
    <tr>

        <td colspan="3" style="text-align: right;"><?php echo $price; ?></td>
    </tr>
</table>

但它不起作用。输出结果与图片中的结果输出不同

如何修复我的代码，以便将结果作为输出产生图像？

任何帮助非常感谢

干杯

Answer 1

作为替代方案，只需使用数组将它们组合在一起即可。首先建立一系列费率：

$rates = array(
    'sgl' => array('rate' => 1, 'type' => 'Single',),
    'dbl' => array('rate' => 2, 'type' => 'Double',),
    'twn' => array('rate' => 2, 'type' => 'Twin',),
    'trp' => array('rate' => 3, 'type' => 'Triple',),
    'quad' => array('rate' => 4, 'type' => 'Quad',),
);

有点像桌子，你有价格，标签和东西。

然后，构建一个输入数组，以便将其应用到您的数据库中并使用该键进行计算。

示例：

// input
$input = array('sgl' => $sgl, 'dbl' => $dbl, 'twn' => $twn, 'trp' => $trp, 'quad' => $quad);
// lay them all out as an array

现在你可以匹配键：

<?php

$sgl = 2;
$dbl = 0;
$twn = 1;
$trp = 0;
$quad = 0;

// input
$input = array('sgl' => $sgl, 'dbl' => $dbl, 'twn' => $twn, 'trp' => $trp, 'quad' => $quad);

$price_room = 250000;

$rates = array(
    'sgl' => array('rate' => 1, 'type' => 'Single',),
    'dbl' => array('rate' => 2, 'type' => 'Double',),
    'twn' => array('rate' => 2, 'type' => 'Twin',),
    'trp' => array('rate' => 3, 'type' => 'Triple',),
    'quad' => array('rate' => 4, 'type' => 'Quad',),
);

$total = 0;
foreach($input as $key => $user_input) {
    if($user_input > 0) {
        // all of the data are pushed in here
        $result[] = array(
            'no' => $user_input,
            'room_type' => $rates[$key]['type'],
            'price' => $rates[$key]['rate'] * $price_room,
        );

        $total += $rates[$key]['rate'] * $price_room;
    }
}

?>

至于演示文稿，普通的html标记和foreach应该可以正常使用：

<table border="1" cellpadding="10">
<thead><tr><th>No</th><th>Room Type</th><th>Price</th></tr></thead>
<?php foreach($result as $r): ?>
    <tr>
        <td><?php echo $r['no']; ?></td>
        <td><?php echo $r['room_type']; ?></td>
        <td><?php echo $r['price']; ?></td>
    </tr>
<?php endforeach; ?>
<tr>
    <td colspan="3" align="right"><?php echo $total; ?></td>
</tr>
</table>

请使用此代码，它会以您期望的方式输出。

    <?php
    $sgl = 2;
    $dbl = 0;
    $twn = 1;
    $trp = 0;
    $quad = 0;

    $price_room = 250000;

    $rooms = array();

    $counter = 0;
    if($sgl>0){
        $counter++;
        $room_type = 'Single';
        $price = $price_room * 1;
        $rooms[$room_type] = $price;
    }

    if($dbl>0){
        $counter++;
        $room_type = 'Double';
        $price = $price_room * 2;
        $rooms[$room_type] = $price;
    }

    if($twn>0){
        $counter++;
        $room_type = 'Twin';
        $price = $price_room * 2;
        $rooms[$room_type] = $price;
    }

    if($trp>0){
        $counter++;
        $room_type = 'Triple';
        $price = $price_room * 3;
        $rooms[$room_type] = $price;
    }

    if($quad>0){
        $counter++;
        $room_type = 'Quad';
        $price = $price_room * 4;
        $rooms[$room_type] = $price;
    }


    // echo $counter;

?>

<table border="1">
    <tr>
        <td>No</td>
        <td>Room type</td>
        <td>Price</td>
    </tr>
<?php 
    $no=1;$total_price =0;
    foreach($rooms as $toom_type=>$room_price){
?>
    <tr>
        <td><?php echo $no; ?></td>
        <td><?php echo $toom_type; ?></td>
        <td><?php echo $room_price; ?></td>
    </tr>
<?php
        $total_price += $room_price;
        $no++;
    }
?>
    <tr>

        <td colspan="3" style="text-align: right;"><?php echo $total_price ; ?></td>
    </tr>
</table>

您可以使用compact将变量添加到数组中（尽管您可以通过其他方式执行此操作）。

循环遍历它们，并使用switch设置值和输出。

$sgl = 2;
$dbl = 0;
$twn = 1;
$trp = 0;
$quad = 0;
$price_room = 25000;

// compact the variables into an array
$rooms = compact('sgl', 'dbl', 'twn', 'trp', 'quad');

echo '<table border="1">
    <tr>
        <td>No</td>
        <td>Room type</td>
        <td>Price</td>
    </tr>';
// set start values
$no = 1;
$total = 0;
// loop through array
foreach ($rooms as $type => $rm)
{
    // only output if greater than 0
    if ($rm > 0)
    {
        // set the values based on the type
        switch ($type) {
            case 'sgl':
                $room_type = 'Single';
                $price = $price_room * 1;
                break;
            case 'dbl':
                $room_type = 'Double';
                $price = $price_room * 2;
                break;
            case 'twn':
                $room_type = 'Twin';
                $price = $price_room * 2;
                break;
            case 'trp':
                $room_type = 'Triple';
                $price = $price_room * 3;
                break;
            case 'quad':
                $room_type = 'Quad';
                $price = $price_room * 4;
                break;
        }
        // output the row
        echo '<tr>
            <td>'.$no.'</td>
            <td>'.$room_type.'</td>
            <td>'.($rm * $price).'</td>
        </tr>';
        // add to total
        $total += $rm * $price;
        // increment number
        $no++;
    }
}
// output the total and close the table
echo '<tr>
        <td colspan="3" style="text-align: right;">'.$total.'</td>
    </tr>
</table>';
