How to get the total number of pages in MPDF?

Question

I'm using PHP MPDF to create PDF files. At the footer I'm able to print the current page number using

{PAGENO}

But how do I get the total number of pages in the PDF file? So that in the footer I can print like:

Page (Current Page) of (Total number of pages)   
Page 1 of 6

Answer 1

According to the official documentation:

$mpdf=new mPDF();
$mpdf->setFooter("Page {PAGENO} of {nb}");
