What are the limitations of using PHP for converting various file formats to PDF?

One limitation of using PHP for converting various file formats to PDF is that PHP does not have built-in support for all file formats. To overcome this limitation, you can utilize third-party libraries or tools that support a wider range of file formats for conversion.

// Example using the mPDF library for converting HTML to PDF
require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$html = '<h1>Hello, World!</h1>';
$mpdf->WriteHTML($html);
$mpdf->Output('output.pdf', 'F');
