TCPDF如何在HTML里面写PHP代码

Question

我正在使用 TCPDF 创建库存清单打印。 我在将 while 循环放入 HTML 标签时遇到了一个问题，它出错了，我该如何正确编写它。 我尝试过所以我写在下面。 日期和lastinserted和grandtotal工资余额都显示得很好。 只有我需要while循环我试过很多次但我不能

<?php

$pdf->setPrintFooter(false);
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetFont('dejavusans', '', 10);
$pdf->AddPage();
include("db.php");
