PHP 动态 HTML 到带有 mPDF 的 PDF 证书

Question

正在寻找一种方法将 PHP 动态 html 输出到一个看起来像证书的 PDF 文档中 - 我有 html 的证书看起来不错，但是当我使用 mPDF 来return 将 html 结果转换为 PDF，但我什么也没得到。我确定这是 html 存储在 php var 中的方式，脚本需要在 html 之外，但我不确定如何完成此操作？

<?php

<SCRIPT>

Answer 1

html 中的 javascript 变量在绘制 php 页面后加载。 javascript var 需要通过 POST、GET 或查询字符串传递给 php var，并在刷新或新页面中获取 - $html 因此需要只是 html 而不是包含脚本。
