In what ways can PHP developers optimize their code for generating PDFs to ensure cross-browser compatibility, especially when targeting browsers like MS-IE?

When generating PDFs in PHP for cross-browser compatibility, especially with browsers like MS-IE, developers should ensure that the PDF is properly formatted and uses compatible features. One way to optimize code for this is to use libraries like TCPDF or FPDF that are known for their cross-browser compatibility. Additionally, developers should test the generated PDFs in various browsers to ensure they display correctly.

// Example using TCPDF library for generating a PDF
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', 'I');
