Tag: concat

As requirement for one of my projects, I needed to concatenate multipe PDF files provided by the user into just one file.

To achieve this, we need the TCPDF and FPDI libraries.

Class to concatenate pdf, Pdf_concat.class.php:

require_once('./includes/tcpdf/config/lang/eng.php');
require_once('./includes/tcpdf/tcpdf.php');
require_once('./includes/fpdi/fpdi.php');

class Pdf_concat extends FPDI {
     var $files = array();
	 
     function setFiles($files) {
          $this->files = $files;
     }
	 
     function concat() {
          foreach($this->files AS $file) {
               $pagecount = $this->setSourceFile($file);
               for ($i = 1; $i <= $pagecount; $i++) {
                    $tplidx = $this->ImportPage($i);
                    $s = $this->getTemplatesize($tplidx);
                    $this->AddPage('P', array($s['w'], $s['h']));
                    $this->useTemplate($tplidx);
               }
          }
     }
}
