【中文标题】用双引号或单引号打印 HTML 和 PHP 代码【英文标题】：Print the HTML and PHP Code in Double or single quotation marks 【发布时间】：2017-06-22 11:19:32 【问题描述】：

我正在显示从 php 中的数据库获取数据的 html 表，并将其导出到 PDF 页面中...一切都很好，但是当 PDF 文件下载时，除了来自 mysql 的值之外，它会在表中显示 php 代码，并且问题在于引号，那么如何用引号编写代码，以便在表格中准确显示除 php 代码之外的值？

点击时

<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

【参考方案2】：

写下这些行：

<td style='color:red;'><b><?php echo getTotalDistrictUnique();?></b></td>

像这样：

<td style='color:red;'><b>".getTotalDistrictUnique()."</b></td>

你的代码是这样构建的：

<?php 
 ...
 <?php // this is wrong, the opening PHP tag is still alive
  ... getTotalDistrictUnique()...
 ?>
?>

【讨论】：

mPDF错误：部分数据已经输出到浏览器，无法发送PDF文件比你在getTotalDistrictUnique() 函数中的echo | print_r | var_dump | ...（输出）命令。该函数必须返回（不显示）您的数据。永远欢迎。【参考方案3】：
