Question

好吧，我有一张桌子，上面有一些日期和时间。我使用while循环从数据库中获取数据。

我想在日期更改后将1行添加到下一行，这样我就可以计算出de day的总小时数。每天更换一次后，我只需要排一列（例如下面的图片）

            $stmt5->execute();   
            while($row = $stmt5->fetch(PDO::FETCH_ASSOC)){
                if($gewerkt == 0){
                    $gewerkt = $row['HOURS_WORKED'];
                }else{
                    $gewerkt = $gewerkt + $row['HOURS_WORKED'];
                }             
                echo "
                <td>" .$row['TRANSACTION_ID']."</td>
                <td>" .$row['RESOURCE_ID']."</td>
                <td></td>
                <td>" .$row['DEPARTMENT_ID']."</td>
                <td>" .$row['WORKORDER_BASE_ID']."/".$row['WORKORDER_LOT_ID'].".".$row['WORKORDER_SPLIT_ID']."-".$row['WORKORDER_SUB_ID'].":".$row['OPERATION_SEQ_NO']."</td>
                <td>" .date('Y-m-d', strtotime($row['TRANSACTION_DATE']))."</td>
                <td>" .TimeValue($row['CLOCK_IN'])."</td>
                <td>" .TimeValue($row['CLOCK_OUT'])."</td>
                <td>" .floatval($row['HOURS_BREAK'])."</td>
                <td>" .floatval($row['HOURS_WORKED'])."</td>
                <td></td>
                <td><form action='' method='POST'>
                            <button class='btn btn-default' type='submit' name='delete'>Verwijderen</button>
                    </form></td>
            </tbody>
            ";
            }

下面的照片是我的桌子的一个例子。如您所见，我的前三行具有相同的日期。在这3行之后，我只希望再增加1行就可以计算出一天的总费用。

您可以在实际显示所有行和小计之前对其进行汇总。这种方法可能会占用一些内存，但是可读性很强。


// aggregate the rows first
while($row = $stmt5->fetch(PDO::FETCH_ASSOC)){
    $row['ROW_DATE'] = date('Y-m-d', strtotime($row['TRANSACTION_DATE']));
    $dateRows[$row['ROW_DATE']]['rows'][] = $row; // aggregate a 2D array
    $dateRows[$row['ROW_DATE']]['HOURS_WORKED'] = isset($dateRows[$row['ROW_DATE']]['HOURS_WORKED'])
        ? $dateRows[$row['ROW_DATE']]['HOURS_WORKED'] + $row['HOURS_WORKED']
        : $row['HOURS_WORKED'];
}

foreach ($dateRows as $date => $rows) {
    // loop through all the rows of the day
    foreach ($rows['rows'] as $row) {
        echo "
        <td>" .$row['TRANSACTION_ID']."</td>
        <td>" .$row['RESOURCE_ID']."</td>
        <td></td>
        <td>" .$row['DEPARTMENT_ID']."</td>
        <td>" .$row['WORKORDER_BASE_ID']."/".$row['WORKORDER_LOT_ID'].".".$row['WORKORDER_SPLIT_ID']."-".$row['WORKORDER_SUB_ID'].":".$row['OPERATION_SEQ_NO']."</td>
        <td>" .$date."</td>
        <td>" .TimeValue($row['CLOCK_IN'])."</td>
        <td>" .TimeValue($row['CLOCK_OUT'])."</td>
        <td>" .floatval($row['HOURS_BREAK'])."</td>
        <td>" .floatval($row['HOURS_WORKED'])."</td>
        <td></td>
        <td>
            <form action='' method='POST'>
                <button class='btn btn-default' type='submit' name='delete'>Verwijderen</button>
            </form>
        </td>\n";
    }

    // display a subtotal row
    echo "
    <td colspan='9'>Subtotal:</td>
    <td>{$rows['HOURS_WORKED']}</td>
    <td></td>
    <td></td>\n";
}

使用Whileloop在表中某处的PHP额外行
