Using Las the constructor parameter should work just fine. Don't mess with the class internals.
使用L作为构造函数的参数应该只是罚款。不要弄乱类的内部结构。
This is my only code and it works fine. Try using the newest release: HTML2PDF.
这是我唯一的代码，它工作正常。尝试使用最新版本：HTML2PDF。
// convert to PDF
require_once('../../vendor/html2pdf_v4.03/html2pdf.class.php');
try
{
$html2pdf = new HTML2PDF('L', 'A4', 'en');
$html2pdf->setDefaultFont('Arial');
$html2pdf->writeHTML($html, false);
$html2pdf->Output('output.pdf', 'D');
}
catch(HTML2PDF_exception $e) {
echo $e;
exit;
}

Or you can add orientation on tag.
或者您可以在标签上添加方向。
<page orientation="landscape" format="A5" > Landscape </page>

This solution also is very good and it's in the documentation:
这个解决方案也很好，它在文档中：
var element = document.getElementById('element-to-print');
var opt = {
margin: 1,
filename: 'myfile.pdf',
image: { type: 'jpeg', quality: 0.98 },
html2canvas: { scale: 2 },
jsPDF: { unit: 'in', format: 'letter', orientation: 'portrait' }
};
// New Promise-based usage:
html2pdf().set(opt).from(element).save();
// Old monolithic-style usage:
html2pdf(element, opt);
