php - 在双引号或单引号中打印 HTML 和 PHP 代码

Question

我正在显示从 PHP 数据库中获取数据的 HTML 表，并在 PDF 页面中导出它...一切都很好，但是当下载 PDF 文件时，除了来自 Mysql 的值外，它在表中显示 php 代码，并且问题在于引号，那么如何用引号编写代码，使其在 php 代码之外的表中准确显示值？

当点击它时

<a href="file.php" class="export-pdf" data-filename="PDFFILE"><button type="button" class="btn btn-success">PDF FORMAT</button></a>

以 PDF 代码“FILE.PHP”导出表格

<?php require_once 'components/app.php'; ?>
<?php
include('mpdf/mpdf.php');
$mpdf=new mPDF();
$mpdf->WriteHTML("

你的代码很乱。字符串中的 PHP 代码只是一个字符串，不再是代码。您应该正确编写代码。

<?php
require_once 'components/app.php';
include('connection.php');
include('mpdf/mpdf.php');

$content = '

            <th>Recreational</th>
            <th>Awareness Raising</th>
            <th>Training</th>
