How to get the number of pages (variable) into a variable before generating a file through mpdf?

Question

PHP

Good afternoon! How to get the total number of pages (a variable for further processing, output through placeholders is not suitable) that will be generated (or during the formation) through the mpdf library?

Answer 1

And how does anyone, including mpdf, know how many pages your document will spread to before all these calculations are done? Between PDF generation and file output, the number of pages is known:

$mpdf->WriteHTML($html);
$pageCount = $mpdf->page;
$mpdf->Output();
