使用dompdf将页面转换为PDF

我想使用dompdf将PHP页面转换为PDF，但我不确定最好的方式来做到这一点。我已经写了我的网页我怎么想它在标准的HTML/PHP提交，并希望它显示像这样，就像一个PDF：使用dompdf将页面转换为PDF

Desired output

我的PHP代码如下。我相信我需要将我的代码放入$html变量中以将其解析为dompdf，但我是一位PHP新手，所以希望得到一些帮助，以了解实现此目的的最佳方式。显然，页面的样式都是从外部CSS文件中引入的，所以我不确定这是否是一个问题？

<?php 
    include("checklog.php"); 
    require_once("watchlist-controller.php"); 
    require_once("dompdf/dompdf_config.inc.php"); 
    $html = 
?>

更新

基于BrianS的评论（谢谢！），我的新代码看起来像下面，但试图查看监视列表中时，我现在得到的只是一个普通的空白页。我已经测试了它没有dompdf的东西，并且页面显示完美，显示了我希望它显示的所有信息，并正确显示。我也用CSS替换了LESS文件并删除了所有的JS。

    include("checklog.php"); 
    require_once("watchlist-controller.php");

另外，如果有帮助，把错误报告让我以下：

试试这个：https://github.com/mreiferson/php-wkhtmltox – GBD 2013-04-28 11:57:35

一些一般建议：如果您只是将输出发送到浏览器，那么运行代码并不会产生什么影响。在这种情况下，您会得到一个错误，您可以使用它来尝试找出代码中缺少的内容。错误并不总是准确地报告问题的根源，但在大多数情况下，它们会为您提供所需的信息，以纠正任何语法问题。 – BrianS 2013-04-29 16:23:38

有多种方式做你想做的事。您的当前逻辑应该可行，但语法不太正确。但是，如果您想坚持使用当前的结构，则可以使用输出缓冲。

<?php 
include("checklog.php"); 
require_once("watchlist-controller.php"); 
require_once("dompdf/dompdf_config.inc.php"); 
ob_start(); 
?> 

<html>...</html> 

<?php 
$html = ob_get_clean(); 
$dompdf = new DOMPDF(); 
$dompdf->load_html($html); 
$dompdf->render(); 
$dompdf->stream("sample.pdf"); 
?>

链接样式表很好。 JavaScript不是，dompdf不支持客户端JS。所以如果你的LESS样式表是必需的，你将不得不将它转换为标准的CSS。

嗨，谢谢你的帮助！我很感激协助。我已经做出了您所建议的更改，但是现在我在尝试下载PDF时正在获得纯白色的页面。根据您的评论，我已更新了原始文章/新代码。 – 2013-04-29 18:37:45

编辑：还添加错误报告消息更新后发布进一步澄清。 – 2013-04-29 19:08:36

大多数警告/通知与dompdf没有任何关系。你所看到的似乎是一个导致你的MySQL查询失败的缺失变量。始终检查查询的状态。例如，'$ query = mysql_query（...）; if（$ query）{...} else {...}'。 – BrianS 2013-04-29 21:23:19

使用下面的简单代码。

require_once 'dompdf/autoload.inc.php'; 
use Dompdf\Dompdf; 
$dompdf = new Dompdf(); 

$html = 'Insert full HTML content'; 
$dompdf->loadHtml($html); 
$dompdf->setPaper('A4', 'landscape'); 
$dompdf->render(); 
$dompdf->stream("codexworld",array("Attachment"=>0));
