Question

我以这种方式从Mysql输出创建一个HTML表：

$i = 0;
while ( $row = mysql_fetch_assoc($result) ) {
    if ( $i == 0 ) {
        echo "<tr>";
        foreach ( array_keys($row) as $fieldName ) echo "<th>".$fieldName."</th>";
        echo "</tr>";
    }
    echo "<tr>";
    foreach ( $row as $value ) echo "<td>".$value."</td>";      
    echo "</tr>";   
    $i++;
}

如果列中有两个或更多相同的单元格，则应使用HTML属性rowspan

自动加入此单元格

我无法找到在同一列中动态创建包含已连接单元格的表格的解决方案。

当您想要更改行数时，您必须做两件事：

检查该列中的下一个值，以了解相同的数量
检查先前的rowspan值以避免打印值不应该（因为前一个有一个rowpan＆gt; 1）

以下是一些带有示例值的代码，以便您可以对其进行测试。第一个foreach()必须替换为while ($row = mysql_fetch_assoc($result)) {才能使其与您的数据库数据一起使用。

// Example datas for tests
$rows = array(
    0 => array(
        'name' => 'Product 1',
        'price' => 20,
        'option_x_included' => 'No',
        'duration' => 12
    ),
    1 => array(
        'name' => 'Product 2',
        'price' => 30,
        'option_x_included' => 'Yes',
        'duration' => 12
    ),
    2 => array(
        'name' => 'Product 3',
        'price' => 45,
        'option_x_included' => 'Yes',
        'duration' => 18
    ),
    3 => array(
        'name' => 'Product 4',
        'price' => 60,
        'option_x_included' => 'Yes',
        'duration' => 24
    )
);

echo '<table>';

$i = 0;
$rowspanValues = array();
foreach($rows as $index => $row) {
// Replace this foreach (for tests) by:
// while ($row = mysql_fetch_assoc($result)) {

    // First row: Column headers
    if ($i == 0) {
        echo '<tr>';
        foreach (array_keys($row) as $fieldName) {
            echo '<th>'.$fieldName.'</th>';

            // Init rowspan value for each column
            $rowspanValues[$fieldName] = 1;
        }
        echo '</tr>';
    }

    // Other rows: Values
    echo '<tr>';
    foreach ($row as $fieldName => $value) {

        if ($rowspanValues[$fieldName] == 1) {
        // rowspan for that column is 1: means that we have not tested next values

            // Test if next values in the same column is the same
            $nextIndex = $index+1;
            while (!empty($rows[$nextIndex][$fieldName]) && $value == $rows[$nextIndex][$fieldName]) {
                // Increment nextIndex to test the row after
                $nextIndex++;

                // Increment current rowspan value
                $rowspanValues[$fieldName]++;
            }

            // Put the calculated rowspan to current cell
            echo '<td rowspan="'.$rowspanValues[$fieldName].'">'.$value.'</td>'; 
        } else {
        // rowspan value > 1: means that the previous column had a bigger rowspan, so this cell must not been printed
            $rowspanValues[$fieldName]--;
        }

    }    
    echo '</tr>';   
    $i++;
}

echo '</table>';

Answer 2

这就是工作：

$result = mysql_query ($sql, $con);

$numRows = mysql_num_rows($result);
while ( $row = mysql_fetch_assoc($result) ) $rows[] = $row;

echo "<table>";
foreach($rows as $index => $row) {
    // First row: Column headers
    if ($index == 0) {
        echo '<tr>';
        foreach (array_keys($row) as $fieldName) {
            echo '<th>'.$fieldName.'</th>';

            // Init rowspan value for each column
            $rowspanValues[$fieldName] = 1;
        }
        echo '</tr>';
    }
    echo '<tr>';
    // Other rows: Values
    foreach ($row as $fieldName => $value) {

        if ($rowspanValues[$fieldName] == 1) {
        // rowspan for that column is 1: means that we have not tested next values

            // Test if next values in the same column is the same
            $nextIndex = $index + 1;            
            while ($value == $rows[$nextIndex][$fieldName]) {
                // Increment nextIndex to test the row after
                $nextIndex++;

                // Increment current rowspan value
                $rowspanValues[$fieldName]++;
            }

            // Put the calculated rowspan to current cell
            echo '<td rowspan="'.$rowspanValues[$fieldName].'">'.$value.'</td>'; 
        } else {
        // rowspan value > 1: means that the previous column had a bigger rowspan, so this cell must not been printed
            $rowspanValues[$fieldName]--;
        }
    }    
    echo '</tr>';   
}
echo '</table>';

使用rowspan从mysql结果创建动态表
