我有一个数组，我想在多个表中显示数据。特定年份和学期的所有模块都应在一个表中。例如，在semester_id 1和year 1中找到的所有模块都应在一个单一的表中

这是我到目前为止的代码
if (isset($rows) && is_array($rows)) {
for ($i = 0; $i < count($rows); $i++) {
/*echo 'Year ID: ' . $rows[$i]['year_id'] . '<br>';
echo 'Semester ID : ' . $rows[$i]['semester_id'] . '<br>';
echo 'Module Code' . $rows[$i]['module_code'] . '<br>';*/
echo <<<HTML
<div class="title">
<h1>Year {$rows[$i]['year_id']}</h1>
</div>
<div class="datagrid">
<table>
<thead>
<tr>
<th>Semester {$rows[$i]['semester_id']}</th>
</tr>
</thead>
<thead>
<tr>
<th>Module Code</th>
<th>Module Name</th>
<th>Credits</th>
<th>Grade</th>
</tr>
</thead>
<tbody>
<tr>
<td>{$rows[$i]['module_code']}</td>
<td>{$rows[$i]['module_name']}</td>
<td>{$rows[$i]['module_credit']}</td>
<td>
<select class="combo">
<option value=""> --Grade-- </option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
<option value="F">F</option>
</select>
</td>
</tr>
<tr class="al">
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td bgcolor="#b3ffb3"><b>S.P.A</b></td>
<td bgcolor="#4dff4d">data</td>
</tr>
</tbody>
</table>
</div>
HTML;
您需要将静态代码放在for循环之外（即all）。
您必须仅为来自数据库的数据生成动态行
ie ({$rows[$i]['module_code']})
不需要使用多个头或表，只需创建一个表，一个头，然后使用内部tr，然后为数组数据创建动态。
<table>
<thead>
<tr>
<th>Module Code</th>
</tr>
</thead>
<tbody>
<?php
for ($i = 0; $i < count($rows); $i++){
?>
<tr>
<td><?php echo $rows[$i]['module_code'] ?></td>
</tr>
<?php } ?>
</tbody>
</table>
这是为了在需要创建单个表时使用。例如，在semester_id 1和year 1中找到的所有模块都应该在一个表中。在这种情况下，在数组中运行表，并设置上面的条件
如果匹配了新表，则继续使用当前表
在简单查询上迭代
SELECT DISTINCT year_id, semester_id FROM tablename;
对于每一行，打印表头并在另一个准备好的语句的行上迭代
SELECT ... FROM yourQuery WHERE year_id = ? AND semester_id = ?;
打印表格底部，在时结束
结束while（外部迭代）
