What are some best practices for handling PDF files in PHP applications?

When handling PDF files in PHP applications, it is important to use libraries like TCPDF or FPDF to generate PDF files, and libraries like PDFlib or pdftk to manipulate existing PDF files. It is also recommended to sanitize user input when working with PDF files to prevent security vulnerabilities. Additionally, consider optimizing PDF file sizes to improve performance. 

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

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('example.pdf', 'D');
