请帮助!!我只是想显示Barangay,这是没有其他重复值的talojongon 让我们说我目前的输出是:
| Barangay | Disease |
__________________________________
| Talojongon | Cancer |
| Talojongon | Cancer |
| Talojongon | Cancer |
我希望将其转为:
| Barangay | Disease |
__________________________________
| Talojongon | Cancer |
| | Cancer |
| | Cancer |
数据库中的接收是疾病和数据库中的状态是barangay ...谢谢...任何建议表示赞赏.. :)

<table id="keywords" class="table table-striped table-bordered">

<th><center>Diseases</th></center>
</tr>
</thead>
<tbody>
<?php
include 'database.php';
$pdo = Database::connect();
$sql = 'SELECT * FROM patients WHERE receive="Cancer"';
foreach ($pdo->query($sql) as $row){
echo '<tr>';
echo '<td><center>'. $row['status'] . '</center></td>';
echo '<td><center>'. $row['receive'] . '</center></td>';
}
Database::disconnect();
?>
</tr>
</tbody>

<?php
include 'database.php';
$pdo = Database::connect();
$sql = 'SELECT * FROM patients WHERE receive="Cancer"';
$counter=0;
foreach ($pdo->query($sql) as $row){
$counter++;
echo '<tr>';
if($counter==1){
echo '<td><center>Cancer</center></td>';
}else{
echo '<td><center></center></td>';
}
echo '<td><center>'. $row['receive'] . '</center></td>';
}
Database::disconnect();
?>
只需回显第一行的状态......

将$row['status']
的最后一个值保存在变量中。如果相同则在输出中留空。
$last_status = null;
foreach ($pdo->query($sql) as $row) {
echo '<tr>';
$status = $row['status'] == $last_status ? '' : $row['status'];
echo '<td style="text-align: center;">' . $status . '</td>';
echo '<td style="text-align: center;">' . $row['receive'] . '</td>';
echo '</tr>';
$last_status = $row['status'];
}
此外,您不应使用过时的<center>
标记,请使用CSS。 </tr>
应该在循环内,而不是在最后。
您可能还应该在查询中使用ORDER BY status
,以便状态相同的所有行都在一起。

这个怎么样?
<?php
include 'database.php';
$pdo = Database::connect();
$sql = 'SELECT * FROM patients WHERE receive="Cancer" order by status';
$last = '';
foreach ($pdo->query($sql) as $row){
echo '<tr>';
if($last == $row['status'])
{
echo '<td></td>';
}
else
{
$last = $row['status'];
echo '<td><center>'. $row['status'] . '</center></td>';
}
echo '<td><center>'. $row['receive'] . '</center></td>';
}
Database::disconnect();
?>
