I want to change something on the page for multi-page documents, depending on which page number is currently being assembled. As I loop through the items being output, is there a way to check the current page number programmatically? (I do not want to simply print the current page in the PDF.)
You can use
$mpdf = new Mpdf\Mpdf();
$pageNumber = count($mpdf->pages);
But the $pages
property of the object is internal and access to it may be disabled in future versions.
