1. we prepare an html file (with design and other unchanged content), in which we put markers like ###numberOfOrders### and the like in the right places
   A pdf is generated from php, something like this code:
   

   function makePdf($filename) {
       if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
           $wkhtmltopdf = '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe"';
       } else {
           $wkhtmltopdf = '/usr/local/bin/wkhtmltopdf';
       }
       $make = "$wkhtmltopdf $filename.html $filename.pdf";
       shell_exec($make);
   }

   
   I tried many PHP generators - they all generate crookedly (or the layout is complicated). And the specified utility generated everything correctly.
