I created an abstraction layer over FPDI (might accommodate other engines). I published it as a Symfony2 bundle depending on a library, and as the library itself.

The bundle

The Library

usage:

public function handlePdfChanges(Document $document, array $formRawData)
{
    $oldPath = $document->getUploadRootDir($this->kernel) . $document->getOldPath();
    $newTmpPath = $document->getFile()->getRealPath();

    switch ($formRawData['insertOptions']['insertPosition']) {
        case PdfInsertType::POSITION_BEGINNING:
            // prepend 
            $newPdf = $this->pdfManager->insert($oldPath, $newTmpPath);
            break;
        case PdfInsertType::POSITION_END: 
            // Append
            $newPdf = $this->pdfManager->append($oldPath, $newTmpPath);
            break;
        case PdfInsertType::POSITION_PAGE: 
            // insert at page n: PdfA={p1; p2; p3}, PdfB={pA; pB; pC} 
            // insert(PdfA, PdfB, 2) will render {p1; pA; pB; pC; p2; p3} 
            $newPdf = $this->pdfManager->insert(
                    $oldPath, $newTmpPath, $formRawData['insertOptions']['pageNumber']
                );
            break;
        case PdfInsertType::POSITION_REPLACE: 
            // does nothing. overrides old file.
            return;
            break;
    }
    $pageCount = $newPdf->getPageCount();
    $newPdf->renderFile($mergedPdfPath = "$newTmpPath.merged");
    $document->setFile(new File($mergedPdfPath, true));
    return $pageCount;
}

I ve done this before  I had a pdf that I generated with fpdf  and I needed to add on a variable amount of PDFs to it    So I already had an fpdf object and page set up  http   www fpdf org   And I used fpdi to import the files  http   www setasign de products pdf-php-solutions fpdi   FDPI is added by extending the PDF class   class PDF extends FPDI               pdffile    Filename pdf        pagecount    pdf- gt setSourceFile  pdffile         for  i 0   i lt  pagecount   i              pdf- gt AddPage               tplidx    pdf- gt importPage  i 1    MediaBox             pdf- gt useTemplate  tplidx  10  10  200            This basically makes each pdf into an image to put into your other pdf  It worked amazingly well for what I needed it for

Both the accepted answer and even the FDPI homepage seem to give botched or incomplete examples   Here s mine which works and is easy to implement   As expected it requires fpdf and fpdi libraries    FPDF  http   www fpdf org en download php FPDI  https   www setasign com products fpdi downloads   require  fpdf php    require  fpdi php      files     doc1 pdf    doc2 pdf    doc3 pdf      pdf   new FPDI        iterate over array of files and merge foreach   files as  file         pageCount    pdf- gt setSourceFile  file       for   i   0   i  lt   pageCount   i               tpl    pdf- gt importPage  i   1    MediaBox             pdf- gt addPage             pdf- gt useTemplate  tpl               output the pdf as a file  http   www fpdf org en doc output htm   pdf- gt Output  F   merged pdf

myokyawhtun s solution worked best for me  using PHP 5 4   You will still get an error though - I resolved using the following   Line 269 of fpdf tpl php - changed the function parameters to   function Image  file   x null   y null   w 0   h 0   type      link     align      resize false   dpi 300   palign      ismask false   imgmask false   border 0       I also made this same change on line 898 of fpdf php

I ve had similar problem in my software  We ve wanted to merge several PDF files into one PDF file and submit it to an outer service  We ve been using the FPDI solution as shown in Christa s solution   However  the input PDF s we ve been using could be in version higher than 1 7  We ve decided to evaluate the FPDI commercial add-on  However  it turned out that some of the documents scanned by our office copier were having malformed indexes  which crashed the commercial FPDI add-on  So we ve decided to use Ghostscript solution as in Chauhan s answer   But then we got some strange metadata in the output PDF properties   Finally we ve decided to join two solutions to get PDF s merged and downgraded by Ghostscript  but the metadata is set by FPDI  We don t know yet how it would work with some advanced formatted pdfs  but for scans we use it works just fine  Here s our class excerpt   class MergedPDF extends  FPDI       private  documentsPaths   array         public function Render                  outputFileName   tempnam sys get temp dir     merged                merge files and save resulting file as PDF version 1 4 for FPDI compatibility          cmd     usr bin gs -q -dNOPAUSE -dBATCH -dCompatibilityLevel 1 4 -sDEVICE pdfwrite -sOutputFile  outputFileName           foreach   this- gt getDocumentsPaths   as  pdfpath                 cmd       pdfpath                       result   shell exec  cmd            this- gt SetCreator  Your Software Name             this- gt setPrintHeader false            numPages    this- gt setSourceFile  outputFileName           for   i   1   i  lt    numPages   i                   tplIdx    this- gt importPage  i                this- gt AddPage                 this- gt useTemplate  tplIdx                      unlink  outputFileName             content    this- gt Output null   S             return  content             public function getDocumentsPaths                 return  this- gt documentsPaths             public function setDocumentsPaths  documentsPaths                 this- gt documentsPaths    documentsPaths             public function addDocumentPath  documentPath                 this- gt documentsPaths      documentPath            The usage of this class is as follows    pdf   new MergedPDF     pdf- gt setTitle  pdfTitle    pdf- gt addDocumentPath  absolutePath1    pdf- gt addDocumentPath  absolutePath2    pdf- gt addDocumentPath  absolutePath3    tempFileName   tempnam sys get temp dir     merged     content    pdf- gt Render    file put contents  tempFileName   content
