PDFMerger in loop

Question:

Can you guys help me, I try to merge a pdf file with PDFMerger, this is the sample code :

$pdf->addPDF('samplepdfs/one.pdf', '1, 3, 4') ->addPDF('samplepdfs/two.pdf', '1-2') ->addPDF('samplepdfs/three.pdf', 'all') ->merge('browser', 'samplepdfs/TEST2.pdf');

and how do I put the 'addPDF('samplepdfs/filename.pdf', '1-2')' in loop, so I can merge many pdf files in php dynamically ?

Answer1:

Well, never used that library, but I would expect this wo work:

<?php $pdfCatalog = [ ['samplepdfs/one.pdf', '1, 3, 4'], ['samplepdfs/two.pdf', '1-2'], ['samplepdfs/three.pdf', 'all'] ]; // $pdf = ....... (instantiation of the $pdf object, missing in your code above...) foreach ($pdfCatalog as $pdfDocument) { $pdf->addPDF($pdfDocument[0], $pdfDocument[1]); } $pdf->merge('browser', 'samplepdfs/TEST2.pdf');

<em>Note: I did not test this, but it appears logical from a normal understanding of the php syntax. It should work unless that library has been implemented totally borked...</em>
