Merging 2 pdf with Zend Framework

merge, pdf, php, zend-framework

Solution

Alright, with the guide from @Gordon 's comment in my question, I got a solution.

- You must have at least Zend Framework 1.11 (I was in 1.9, first error) (found thanks to the 3rd comment to this question)

- You must `clone` page from the PDF you want to merge, else, your application will print an error (self explanatory one) (found thanks to this slideshare which is very interesting for Zend_Pdf)

- The static PDF must be a PDF <= 1.4 (mine was 1.6). Zend_Pdf can't parse PDF which version is > 1.4

I used this application to convert the static files I had in version 1.6 to 1.4.

Here's the rough code I have and work (I know it's not optimised, I'll do it later; but still, it can be useful)

$pdf2show = new Zend_Pdf();  // Initializing the merged PDF
$pdf1 = Zend_Pdf::parse($pdfContent, 1); // $pdfContent is the generated one, got the content...
$template = clone $pdf1->pages[0]; // cloning the page (a must do)
$page1 = new Zend_Pdf_Page($template); // Creating the first page of the merged PDF with the previous content
$pdf2show->pages[] = $page1; // Adding this page to the final PDF
$pdf2 = Zend_Pdf::load('urlToYourPDF.pdf'); // Loading the statif PDF
$template2 = clone $pdf2->pages[0]; // cloning the page (a must do)
$page2 = new Zend_Pdf_Page($template2); // Creating the second page of the merged PDF with the previous content
$pdf2show->pages[] = $page2; // Adding this page to the final PDF
sendToWebBrowser('title', $pdf2show->render());

`sendToWebBrowser` is a function sending the PDF content to browser with the `title` as... title. `$pdf2show->render()` produces the merged PDF content as a string.

Problem

I'm trying to merge 2 PDF, one on my server (not dynamically generated) and one generated just before the merge and not saved anywhere on the server (I just want my client to download it). So I only have the pdf's content. Both PDF have the same format (A4). The merged file will have 2 pages and won't be saved on server as well. Since, I'm using Zend Framework, I would prefer a solution with it (can't find one online...) else any advice ? (common solution found online but doesn't work) Edit : because people are lazy to click. The code is in the link anyway since it's wrong and doesn't work. I try the script below, but I get the error: Uncaught exception 'Zend_Pdf_Exception' with message 'Page is attached to one documen, but rendered in context of another
