Use MPDF to convert .php file with variables to HTML

在php中创建页面后，我正在使用mpdf创建一个看起来像页面的pdf。该页面是收据，因此其某些条目是变量。将收据页面（"Receipt_Template_2.php"）转换为 pdf 的页面的代码是：

<?php
include("MPDF57/mpdf.php");
ob_start();
include "Receipt_Template_2.php"; 
$template = ob_get_contents();
ob_end_clean();
$mpdf=new mPDF('','A4','','',32,25,27,25,16,13,'L'); 
$mpdf->WriteHTML($template);
$mpdf->Output('MyPDF.pdf', 'D');
?>

但是，实际的收据模板页面上正确打印了 php 变量。但是，这些变量不会打印到收据上（字段留空）。谢谢。

我主要在收据模板中使用会话变量，如下所示：

<div id="apDiv1"><img src="Receipt_Template_2.jpg" width="765" height="519"></div>
<div id="apDiv2">
<p><strong><?php echo $_SESSION['firstName'] . ' ' . $_SESSION['lastName'];?></strong>       </p>
  <p><?php echo $_SESSION['address'];?></p>
  <p><?php echo $_SESSION['city'] . ' ' . $_SESSION['province'];?></p>
  <p><?php echo $_SESSION['postal'];?></p>
  <p><?php echo $_SESSION['country'];?></p>
</div>
<div id="apDiv3"><?php echo $_SESSION['dateReceived'];?></div>
<div id="apDiv4"><?php echo date("Y-m-d");?></div>
<div id="apDiv5"><?php echo $_SESSION['locationIssued'];?></div>
<div id="apDiv18">$<?php echo $_SESSION['donationAmount'];?></div>
<div id="apDiv6"><?php echo $preReceiptNumber . $receiptNumber;?></div>

尝试...

ob_start();
include "Receipt_Template_2.php"; 
$template = ob_get_contents();
ob_end_clean();
$mpdf->WriteHTML($template);

试试这个（导入库后）：

$url = "Receipt_Template_2.php";
$CurlConnect = curl_init();
curl_setopt($CurlConnect, CURLOPT_URL, $url);
curl_setopt($CurlConnect, CURLOPT_RETURNTRANSFER, 1 );
$file_contents = curl_exec($CurlConnect);
curl_close($CurlConnect);
$CurlConnect = null;
echo $file_contents;
$html = ob_get_contents();
ob_end_clean();
$mpdf->WriteHTML($html);
$mpdf->Output();
