Is it recommended to use PDF instead of .doc or .rtf files in PHP for document generation?

When generating documents in PHP, it is recommended to use PDF files instead of .doc or .rtf files for better compatibility and consistency across different platforms. PDF files ensure that the document layout remains intact regardless of the device or software used to view it. Additionally, PDF files are more secure and can prevent unauthorized editing of the document content.

// Example PHP code to generate a PDF document 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');
