Are there any specific PHP libraries or tools recommended for converting various file types to PDF?

Converting various file types to PDF in PHP can be achieved using libraries such as TCPDF, Dompdf, or MPDF. These libraries provide functions to generate PDF files from different input sources like HTML, images, or text.

// Example using TCPDF library to convert HTML to PDF

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->writeHTML('<h1>Hello, World!</h1>');
$pdf->Output('example.pdf', 'D');
