Question

我在搜索参数后有一个结果数组，我想打印那个结果。当使用foreach循环打印结果时，我需要检查条件，如果购买日期相同，它们应该打印在同一行。我该如何实现呢？请帮帮我。谢谢你提前

这是我的代码:(我已在控制器中获得结果，然后我将结果附加到视图中）

foreach($res as $key => $row)
{


$i++;
$billfirst='';
$billend= $row['bill_date'];

if( $billfirst != $billend){

echo "<tr>
 <td class='txt'> ".$i."</td>
 <td class='txt'> ".$row['store']."</td>
<td class='txt'> ".$row['cust']."</td>
<td class='txt'> ".$row['name']."</td>
<td class='txt'> ".$row['net_amount']."</td>
<td class='txt'> ".$row['bill_date']."</td>

</tr>" ;

}
else {

echo "<tr><td class='txt'> ".$row['name']."</td>
<td class='txt'> ".$row['net_amount']."</td>
<td class='txt'> ".$row['bill_date']."</td>
</tr>";

}

$billfirst == $billend;
echo "</tbody></table>";

}

您需要创建其他数组来对行进行分组，例如：

$arRows = array();
$billPrevious = "empty";
// save new grouped array
foreach($res as $key => $row) {
    $arRows[$row['bill_date']][] = $row;
}

// show groups - in the way you want to group it visually in table
foreach ($arRows as $key => $arGroup) {
    echo '<tr>';
    $arName = '';
    $arStore = '';
    foreach ($arGroup as $keyInGroup => $row) {
        $arName[] = $row['name'];
        $arStore[] = $row['store'];
    }
    echo '<td>'.implode('<br>', $arName).'</td>';
    echo '<td>'.implode('<br>', $arStore).'</td>';
    echo '</tr>';
}

在foreach循环内进行条件检查，并在一行中打印多个结果
