PHP MySQL - 在循环中间添加一行

Question

我想知道是否可以在 PHP 的循环中间添加一行，而不必使用 WHERE 'team' = 'leader_name' 多次运行查询。假设我正在使用 while ($row = mysqli_fetch_array($results)) 来显示我的结果。在查询中，我将每个团队拉入 1 个查询中。所以我有 5 个团队，我想在每个团队之间有一个分隔符。可能吗？

当前结果:

Team Leader    |    Name
---------------+---------------------
 Team1         |     Name1
 Team1         |     Name2
 Team2         |     Name3
 Team3         |     Name4
 Team3         |     Name5
 Team3         |     Name6
 Team4         |     Name7
 Team4         |     Name8
 Team5         |     Name9
 Team5         |     Name10
 Team5         |     Name11
 Team5         |     Name12

预期结果:

Team Leader    |    Name
======================================
 Team1         |     Name1
 Team1         |     Name2
-------------------------------------
 Totals:       |     2
-------------------------------------
 Team2         |     Name3
-------------------------------------
 Totals:       |     1
-------------------------------------
 Team3         |     Name4
 Team3         |     Name5
 Team3         |     Name6
-------------------------------------
 Totals:       |     3
-------------------------------------
 Team4         |     Name7
 Team4         |     Name8
-------------------------------------
 Totals:       |     2
-------------------------------------
 Team5         |     Name9
 Team5         |     Name10
 Team5         |     Name11
 Team5         |     Name12
-------------------------------------
 Totals:       |     4
-------------------------------------

假设我使用

$data = mysqli_query ("Select * from tbl_name");
while ($row = mysqli_fetch_array($data)) {
    echo "<tr>";
        echo "<td>".$row['Team']."</td>";
        echo "<td>".$row['Name']."</td>";
    echo "</tr>";
}

你会如何实现下面的例子

writeheader();
$team = $data[0]['team'];
$count = 0;
foreach($data as $row){
 $count += 1;
 //if the current row's team is different than previous than add seperator
 if($row['team'] != $team){
   $team = $row['team'];
   writeseperator();
   writetotal($count);
   $count = 0;
 }
 writerow();
}

我应该把它放在哪里？我有点困惑

当然可以。你没有提供你的代码，所以我给你伪代码。

writeheader();
$team = $data[0]['team'];
$count = 0;
foreach($data as $row){
 $count += 1;
 //if the current row's team is different than previous than add seperator
 if($row['team'] != $team){
   $team = $row['team'];
   writeseperator();
   writetotal($count);
   $count = 0;
 }
 writerow();
}
