如何在DOMPDF中使用php变量生成动态PDF？
下面是我使用 DOMPDF 将 HTML 生成为 PDF 的代码，它将生成一个静态 pdf 到这里完美工作，但是当我添加了一些 PHP 变量（在代码中我使用会话变量）来获取用户的动态数据这不会渲染 PDF。 在将 HTML 文件转换为最终 PDF 之前，是否有其他方法可以使用 DOMPDF 将一些动态数据添加到 HTML 文件中？
<?php
//$first_name = "Gopal Kshirsagar"
session_start();
$_SESSION["mandatory_date"]= $mandatory_date;
$_SESSION["first_name"]= $first_name;
$_SESSION["last_name"]= $last_name;
?>
<?php
use Dompdf\Options;
//add autoload.inc.php
require_once "./dompdf/autoload.inc.php";
// reference the Dompdf namespace
use Dompdf\Dompdf;
// instantiate and use the dompdf class
$dompdf = new Dompdf();
//$dompdf->loadhtml($aData['html']);
$dompdf->set_option('isRemoteEnabled', TRUE);
//$dompdf->loadHtml($html);
$dompdf->loadHtml('

Below is my code to generate HTML into PDF using DOMPDF, It will be generating a static pdf up to here perfectly working fine, but when I have added some PHP variables (in the code I am using session variables) to get users' dynamic data that will not render PDF.
Is there any other way to add some dynamic data into the HTML file using DOMPDF before it converts into a final PDF?
<?php
//$first_name = "Gopal Kshirsagar"
session_start();
$_SESSION["mandatory_date"]= $mandatory_date;
$_SESSION["first_name"]= $first_name;
$_SESSION["last_name"]= $last_name;
?>
<?php
use Dompdf\Options;
//add autoload.inc.php
require_once "./dompdf/autoload.inc.php";
// reference the Dompdf namespace
use Dompdf\Dompdf;
// instantiate and use the dompdf class
$dompdf = new Dompdf();
//$dompdf->loadhtml($aData['html']);
$dompdf->set_option('isRemoteEnabled', TRUE);
//$dompdf->loadHtml($html);
$dompdf->loadHtml('
