I want to add the page numbers in the footer.

Answer 1

You can get the number of pages in the pdf using $pdf->pages and loop through them increasing the index and rendering them at the same time. Something as follows;

$number_pages = sizeof($pdf->pages);

foreach($pdf->pages AS $key => $page) {
    $page->setFillColor(new Zend_Pdf_Color_GrayScale(0));
    $page->drawText(($key + 1) . "/$number_pages", 540, 15, 'UTF-8');
}
