PHP 转 PDF 分页
我正在使用 dompdf HTML 到 PDF 转换器根据某些变量动态生成 PDF 文件。我有一个脚本创建一个 PHP 文件，然后读取该 PHP 文件以提示使用 dompdf 下载 PDF 文件。
我唯一的问题是输出并不真正关心它何时破坏 PDF 中的页面。例如，如果我在第 1 页末尾有一个表格，它不会将第 1 页的剩余部分移动到第 2 页，而是将表格切成两半，并将一半放在第 1 页，一半放在第 2 页。
我想要为了避免这种情况，请让脚本截断 PDF 页面，以便元素在整个文档中简洁对齐。
有没有办法用 CSS、PHP 或其他方式做到这一点？
以下是将数据输出到 PHP 文件的脚本：
$filename = 'dompdf/www/test/' . $_GET['rubric'] . '_' . $_GET['student'] . '.php';
$somecontent = "

I'm using the dompdf HTML to PDF converter to dynamically generate PDF files based on certain variables. I have the script creating a PHP file, and then reading from that PHP file to prompt the download of a PDF file using dompdf.
My only problem is that the output doesn't really care when it breaks the page in the PDF. For example, if I have a table towards the end of page 1, rather than moving the remainder of page 1 to page 2, it will cut the table in half and put one half on page 1 and one half on page 2.
I want to avoid this, and have the script truncate the PDF page so elements are succinctly aligned throughout the document.
Is there a way to do this in CSS, PHP, or some other way?
Here's the script that is outputting the data to a PHP file:
$filename = 'dompdf/www/test/' . $_GET['rubric'] . '_' . $_GET['student'] . '.php';
$somecontent = "
