What are the best practices for handling PDF files in PHP to ensure a seamless viewing experience for users?

When handling PDF files in PHP, it is important to ensure that the files are properly processed and displayed to users without any issues. One way to achieve this is by using a library like TCPDF or FPDF to generate and manipulate PDF files. These libraries provide functions to create PDFs, add content, and customize the appearance. Additionally, it is essential to handle file uploads securely and validate user input to prevent any malicious attacks. 

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

// Create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// Add a page
$pdf->AddPage();

// Set some content
$pdf->SetFont('helvetica', '', 12);
$pdf->Write(0, 'Hello, World!');

// Output the PDF as a file
$pdf->Output('example.pdf', 'D');
