Question

以下是我使用dompdf显示pdf的代码，但错误无法加载pdf PDF.js v0.8.787（build：58407cf）消息：InvalidPDFException

表名是acad_act，数据库名是pbas_db。数据库连接的详细信息存储在db_connect.php中。任何帮助都会很明显

    <?php
            include('db_connect.php');
            require 'dompdf/dompdf_config.inc.php';

    $sqlinv="SELECT * FROM acad_act";
    $res_inv = mysql_query($sqlinv) or die(mysql_error());
    while ($sql3=mysql_fetch_array($res_inv)) {
            $inv_id = $sql3['User_id'];
            $date = $sql3['Year'];
            $cname = $sql3['Gen_Info_AQ'];
            $subtotal = $sql3['Gen_Info_NOC'];
            $disc = $sql3['Gen_Info_Place'];
            $subtotal2 = $sql3['Gen_Info_Duration'];
            $tax = $sql3['Gen_Info_SA'];
            $gtotal = $sql3['Gen_Info_Aqyear'];
    }

    $dompdf= new DOMPDF();

   $html .="<html>
        <head>
        <style>
    body {
        font-family: arial;

    table {

            </tr>
    </thead>
    <tbody>
            <tr>
            <td>" . $inv_id . "</td>
            <td>" . $date . "</td>
            <td>" . $cname . "</td>

            </tr>
    </tbody>
    </table>
    </body>
    </html>";

    $dompdf->load_html($html);
    $dompdf->render();

    $dompdf->stream("sample.pdf");

    exit(0);
    ?>

异常是由于浏览器中安装了pdf.js插件。 pdfjs不显示错误，而是显示不显示错误的异常。只需删除pdfjs插件，就可以看到所需的错误。
