    $result = mysqli_query($connect, $sql);
    if(mysqli_num_rows($result) > 0)
    {
        $output .= '
            <table class="table" bordered="1">
                <tr>
                    <th>First Name</th>
                    <th>Middle Name</th>
                    <th>Last Name</th>

            ';
            while($row = mysqli_fetch_array($result))
            {
                $output .= '
                <tr>
                    <td>'.$row["fname"].'</td>
                    <td>'.$row["mname"].'</td>

                </tr>
            ';
        }
        $output .= '</table>';
        header("Content-Type: application/xls");
        header("Content-Disposition: attachment; filename=download.xls);
        echo $output;
    }
}
?>

Answer 1

你在 header(( 中丢失了一个 ' " '。

header("Content-Disposition: attachment; filename=download.xls);应该是

header("Content-Disposition: attachment; filename=download.xls");
