How can one ensure compatibility and consistency when generating PDF or XLS files in PHP across different platforms or devices?

Ensuring compatibility and consistency when generating PDF or XLS files in PHP across different platforms or devices can be achieved by using libraries like TCPDF or PHPExcel that provide a standardized way to create these files. These libraries handle the complexities of different platforms and devices, ensuring that the generated files look consistent regardless of where they are viewed. 

// Example using TCPDF for generating PDF files
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('example.pdf', 'D');
