Question

我想在数组中计算重复的order_id，并根据表格单元格上的结果打印rowspan。我不确定如何用PHP实现这一点，任何帮助都表示赞赏。

我有这样的php数组：

Array (
[0] => Array
    (
        [order_id] => 1374282003
        [status] => 1
        [mark] => Casio
        [model] => W-81
        [price] => 10.00
    )

[1] => Array
    (
        [order_id] => 1374282003
        [status] => 1
        [mark] => Casio
        [model] => W-81
        [price] => 10.00
    )

[2] => Array
    (
        [order_id] => 1374282573
        [status] => 1
        [mark] => Casio
        [model] => W-81
        [price] => 10.00
    )

[3] => Array
    (
        [order_id] => 1374282573
        [status] => 1
        [mark] => Casio
        [model] => W-81
        [price] => 10.00
    )

[4] => Array
    (
        [order_id] => 1374282573
        [status] => 1
        [mark] => Casio
        [model] => W-81
        [price] => 10.00
    )

）

我想在表格单元格上使用rowspan

<table>
<tr>
<td>Order</td>
<td>Product</td>
<td>Price</td>
<td>Status</td>
</tr>
<tr>
  <td rowspan="2">1374282003</td>
  <td>Casio</td>
  <td>10</td>
  <td>1</td>
</tr>
<tr>
  <td>Casio</td>
  <td>10</td>
  <td>1</td>
</tr>
<tr>
<td rowspan="3">1374282573</td>
  <td>Casio</td>
  <td>10</td>
  <td>1</td>
</tr>
<tr>
  <td>Casio</td>
  <td>10</td>
  <td>1</td>
</tr>
<tr>
  <td>Casio</td>
  <td>10</td>
  <td>1</td>
</tr>
</table>

这是数组循环的代码

<?php
$rowspan = array_count_values(array_map(function($item) { return $item['order_id']; }, $result));
foreach( $result as $row) {
?>
<tr>
  <td rowspan="<?php echo $rowspan[$row['order_id']]"><?php echo $row['order_id']; ?></td>
  <td><?php echo $row['mark']. " " .$row['model']; ?></td>
  <td>1</td>
  <td><?php echo number_format($row['price'], 2, '.', ','); ?> kuna</td>
  <td><?php echo $row['status']; ?></td>
</tr>
<?php } ?>

它将起作用

function check_next_rowspan($sql_values, $checkkey, $rowspan) {
    $current_id = $sql_values[$checkkey]['id'];
    if(count($sql_values) != $checkkey+1) {
        if($sql_values[$checkkey+1]['id'] == $current_id) {
            $rowspan++;
            return check_next_rowspan($sql_values, $checkkey+1, $rowspan);
        }
    }                   
    return $rowspan;
}

function check_previous_rowspan($sql_values, $checkprevkey) {
    if($checkprevkey != 0) {
        if($sql_values[$checkprevkey]['id'] == $sql_values[$checkprevkey-1]['id']) {
            return true;
        }
    }
    return false;
}   

$sql_values = array(
                    array('id'=>'1', 'value'=>'test1'),
                    array('id'=>'1', 'value'=>'test2'),
                    array('id'=>'1', 'value'=>'test3'),
                    array('id'=>'2', 'value'=>'test4'),
                    array('id'=>'3', 'value'=>'test5'),
                    array('id'=>'3', 'value'=>'test6'),
                    array('id'=>'3', 'value'=>'test7'),
                    array('id'=>'4', 'value'=>'test8'),
                    array('id'=>'4', 'value'=>'test9'),
                );
$rowspan = 1;
$tablehtml = '';
foreach($sql_values as $key => $sql_value){ 
    $tablehtml .= '<tr>';
    $current_id = $sql_value['id'];
    $rowspancount = check_next_rowspan($sql_values, $key, $rowspan);
    if($rowspancount > 1) {
        $checkprevid = check_previous_rowspan($sql_values, $key);
        if($checkprevid) {
            $tablehtml .= '<td>'. $sql_value['value'] .'</td>';
        } else {
            $tablehtml .= '<td rowspan="'.$rowspancount.'">'. $sql_value['id'] .'</td><td>'. $sql_value['value'] .'</td>';
            $rowspancount = 1;
        }
    } else {
        $checkprevid1 = check_previous_rowspan($sql_values, $key);
        if($checkprevid1) {
            $tablehtml .= '<td>'. $sql_value['value'] .'</td>';
        } else {
            $tablehtml .= '<td>'. $sql_value['id'] .'</td><td>'. $sql_value['value'] .'</td>';
        }                   
    }
    $tablehtml .= '</tr>';
}

$html = '<!DOCTYPE html>
        <html>
        <head>
            <title></title>
        </head>
        <body>
            <table border="1">
                '.$tablehtml.'
            </table>
        </body>
        </html>';
echo $html;

Answer 2

在用于填充表数据的循环中尝试使用：

if(in_array($item['order_id'], $tempArray))
{
    $rowspan += count($tempArray);
}
$tempArray[] = $item['order_id'];

Answer 3

    <?php
$rowspan = array_count_values(array_map(function($item) { return $item['order_id']; }, $result));
foreach( $result as $row) {
?>
<tr>
  <td rowspan="<?php echo $rowspan[$row['order_id']]"><?php echo $row['order_id']; ?></td>
  <td><?php echo $row['mark']. " " .$row['model']; ?></td>
  <td>1</td>
  <td><?php echo number_format($row['price'], 2, '.', ','); ?> kuna</td>
  <td><?php echo $row['status']; ?></td>
</tr>
<?php } ?>

好的，在这里，你有一些PHP，然后它围绕着一些HTML，然后它进入一些PHP，并且和。最终，这会让你发疯。

首先将PHP标记减少到每个文件一个或两个。它并不意味着通过跳入和跳出PHP引擎来进行字符串处理。所以切换到这样的事情：

<?php
$rowspan = array_count_values(array_map(function($item) { return $item['order_id']; }, $result));
foreach( $result as $row){
    echo "<tr>\n";
    echo "<td rowspan=" . $rowspan[$row['order_id']] .$row['order_id'] ."></td>\n" ;
    echo "<td><" .$row['mark']. " " .$row['model'] . "></td>\n";
    echo "<td>1</td>";
    echo "<td>" . $row['order_id']. "</td>";
    echo "<td><" . number_format($row['price'], 2, '.', ',') . "> kuna</td>\n";
    echo "<td><" .$row['status'] ."></td>\n";
    echo "</tr>\n";
    } 
?>
