php - Creating a new PDF by Merging PDF documents using TCPDF

Question

How can I create a new document using other PDFs that I'm generating?

I have methods to create some documents, and I want to merge them all in a big PDF, how can I do that with TCPDF?

I do not want to use other libs.

TCPDF has a tcpdf_import class, added in 2011, but it is still "under development". If you don't want to use anything outside of TCPDF, you're out of luck!

But FPDI is an excellent addition to TCPDF: it's like an addon. It's as simple as this:

require_once('tcpdf/tcpdf.php');
require_once('fpdi/fpdi.php'); // the addon

// FPDI extends the TCPDF class, so you keep all TCPDF functionality
$pdf = new FPDI(); 

$pdf->setSourceFile("document.pdf"); // must be pdf version 1.4 or below
// FPDI's importPage returns an object that you can insert with TCPDF's useTemplate
$pdf->useTemplate($pdf->importPage(1)); 

Done!
