使用dompdf将页面转换为PDF

我正在尝试使用dompdf将PHP页面转换为PDF，但我不确定最佳方法。我已经在页面上写了我希望它如何以标准HTML / PHP呈现，并希望它像这样显示，就像PDF一样：

Desired output

我的PHP代码如下。我相信我需要将我的代码放入$html变量以将其解析为dompdf，但我是一个PHP新手，所以我们希望得到一些帮助，知道实现这一目标的最佳方法是什么。显然，页面的样式都是从外部CSS文件中引入的，所以我不确定这是不是一个问题？

<?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！），我的新代码如下所示，但是我在尝试查看监视列表时现在只得到一个简单的空白页面。我在没有dompdf的情况下对它进行了测试，页面看起来很完美，显示了我想要显示的所有信息，并且显示正确。我还用CSS替换了LESS文件并删除了所有JS。

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

有很多方法可以做你想做的事。您当前的逻辑应该可行，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");
?>

链接的样式表很好。 JavaScript不是，dompdf不支持客户端JS。因此，如果您需要LESS样式表，则必须将其转换为标准CSS。

使用以下简单代码。

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));
