这是我的 php 代码:从 Mysql 中检索一个表并将其打印在页面上。

代码:

<?php

// Inialize session
session_start();

// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['username'])) {
header('Location: index.php');
}

?>

基本上它看起来有点像这样:

Sql table

我需要的是此页面上的一个按钮,单击该按钮即可将同一张表下载为 PDF 文件。

如有任何帮助,我们将不胜感激。

最佳答案

将 html 轻松转换为 pdf 的唯一可行解决方案是使用 domPdf 库 https://code.google.com/p/dompdf/ .

您可以使用 ?pdf get 参数添加指向同一页面的链接,并在 $_GET['pdf'] 出现时让您的 php 代码通过 dompdf 输出而不是将其回显给浏览器。

用法见wiki: https://code.google.com/p/dompdf/wiki/Usage

我认为在您的情况下,最简单的方法是添加:if ( $_GET['pdf'] ) ob_start();到页面顶部。 (启动输出缓冲区:参见 http://php.net/manual/en/function.ob-start.php

if ( $_GET['pdf'] ) {
$html = ob_get_contents(); // this fills $html with all your output generated above.

//do the dompdf stuff here , using the $html variable.

}

到您页面的底部..
