What are some alternative libraries or tools that can be used in PHP to generate PDFs from HTML without encountering layout issues like shifting or overlapping?

When generating PDFs from HTML in PHP, layout issues like shifting or overlapping can occur due to differences in rendering between HTML and PDF. One way to avoid these problems is to use a library or tool that specifically handles HTML to PDF conversion with better accuracy and control over layout. One alternative library that can be used to generate PDFs from HTML in PHP without encountering layout issues is Dompdf. Dompdf is a popular PHP library that converts HTML and CSS to PDF documents. It provides good support for CSS styles and layouts, resulting in accurate rendering of HTML content in the generated PDF. Here is an example PHP code snippet using Dompdf to generate a PDF from HTML:

<?php
// Include the Dompdf library
require_once 'dompdf/autoload.inc.php';

// Create a new Dompdf instance
$dompdf = new Dompdf\Dompdf();

// Load HTML content from a file or string
$html = '<html><body><h1>Hello, World!</h1></body></html>';

// Load HTML into Dompdf
$dompdf->loadHtml($html);

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF
$dompdf->stream('output.pdf');
?>
