How can one ensure compatibility and consistency when working with PDF files in PHP?

When working with PDF files in PHP, it is important to ensure compatibility and consistency across different platforms and devices. One way to achieve this is by using a library like TCPDF or FPDF to generate PDF files, as these libraries provide a consistent way to create PDFs that are compatible with various PDF viewers. Additionally, it is important to test the PDF files on different platforms and devices to ensure that they display correctly. 

// Example using TCPDF library to generate a PDF file
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');
