Question

我正在尝试从MySql数据库中导出一个表，以使用PHP进行处理。但是我收到文件格式或文件扩展名无效的错误。我当前的代码如下：

$db = JFactory::getDBO();
$output = '';

$query = "SELECT * FROM  student_management_module";
$db->setQuery($query);
$rows = $db->loadObjectList();

$output .= '
    <table class="table" bordered="1">
        <tr>
            <th>Name</th>
            <th>Email</th>
            <th>Program</th>
            <th>Class</th>
            <th>Start Date</th>
            <th>End Date</th>
        </tr>
';

foreach ($rows as &$row) {
    $output .= '
        <tr>
            <td>'.$row->name.'</td>
            <td>'.$row->email.'</td>
            <td>'.$row->program.'</td>
            <td>'.$row->class.'</td>
            <td>'.$row->start_date.'</td>
            <td>'.$row->end_date.'</td>
            <td>'.$row->student_id.'</td>
    ';
}
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment; filename='download.xlsx");
header("Pragma: no-cache");

$output .= '</table>';
echo $output;

在此先感谢您的帮助。

将文件名的扩展名从.xlsx更改为.xls。

如果在此之后仍然遇到问题，则注册表中的扩展名可能具有不正确的MIME类型；修复步骤和更多信息，请参见下面的链接。
