Are there any best practices or recommended libraries for handling PDF files in PHP?

Handling PDF files in PHP can be done using libraries like TCPDF, FPDF, or Dompdf. These libraries provide functions to create, read, and manipulate PDF files easily. It is recommended to use these libraries for better performance and functionality when working with PDF files in PHP.

// Example using TCPDF library to create a PDF file
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(40, 10, 'Hello World!');
$pdf->Output('example.pdf', 'D');
