What common issues can arise when using DOMPDF to generate PDFs from HTML code in PHP?

One common issue when using DOMPDF to generate PDFs from HTML code in PHP is that certain CSS properties or HTML elements may not be fully supported, leading to formatting issues or missing content in the generated PDF. To solve this, you can try simplifying your HTML and CSS, avoiding complex layouts or styles that may not be fully compatible with DOMPDF.

// Example code snippet to generate PDF using DOMPDF with simplified HTML and CSS

require_once 'dompdf/autoload.inc.php';

use Dompdf\Dompdf;
use Dompdf\Options;

// HTML content with simplified CSS
$html = '<html><head><style>body { font-family: Arial, sans-serif; }</style></head><body><h1>Hello, World!</h1></body></html>';

// Initialize DOMPDF
$options = new Options();
$options->set('isHtml5ParserEnabled', true);
$options->set('isPhpEnabled', true);
$dompdf = new Dompdf($options);

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

// Render PDF (optional: set paper size and orientation)
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();

// Output PDF
$dompdf->stream('output.pdf', array('Attachment' => 0));
