php - pdf 下载 html2pdf

Question

我正在使用 html2pdf 类生成 pdf。在我的问题中，它为 html 代码生成 pdf，但它没有提供下载该 pdf 的对话框选项。请帮助我的类(class)。

<?php
ob_start();
include(dirname(__FILE__).'/res/pdf_demo.php');
$content = ob_get_clean();

// conversion HTML => PDF
require_once(dirname(__FILE__).'/../html2pdf.class.php');
try
{
    $html2pdf = new HTML2PDF('P','A4', 'fr', false, 'ISO-8859-15');
    $html2pdf->pdf->SetDisplayMode('fullpage');
    $html2pdf->writeHTML($content, isset($_GET['vuehtml']));
    $html2pdf->Output('pdf_demo.pdf'); 
}
catch(HTML2PDF_exception $e) { echo $e; }
?>
