How can PHP be used to add numbering to PDF documents and display the number on the document?

To add numbering to PDF documents using PHP, you can utilize a library like TCPDF or FPDF. These libraries allow you to generate PDF documents programmatically and add various elements, including text with numbering. You can create a loop to iterate through the pages of the PDF document and add the desired numbering to each page. 

require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();

$number = 1;
$total_pages = $pdf->getNumPages();

for ($i = 1; $i <= $total_pages; $i++) {
    $pdf->setPage($i);
    $pdf->SetFont('helvetica', '', 12);
    $pdf->Text(10, 10, 'Page ' . $number);
    $number++;
}

$pdf->Output('numbered_document.pdf', 'I');
