PHP library for merging multiple PDFs using FPDI


Install using composer. Exists as iio/libmergepdf in the packagist repository.

composer require iio/libmergepdf:~3.0


Append the first ten pages of bar.pdf to foo.pdf:

use iio\libmergepdf\Merger;
use iio\libmergepdf\Pages;

$m = new Merger();
$m->addFromFile('bar.pdf', new Pages('1-10'));
file_put_contents('foobar.pdf', $m->merge());

Bulk add files from an iterator:

use iio\libmergepdf\Merger;
$m = new Merger();
$m->addIterator(array('A.pdf', 'B.pdf'));
file_put_contents('AB.pdf', $m->merge());

Bulk add files using symfony finder:

use iio\libmergepdf\Merger;
use Symfony\Component\Finder\Finder;

$finder = new Finder();

$m = new Merger();

file_put_contents('finder.pdf', $m->merge());


Unit tests requires dependencies to be installed using composer:

$ curl -sS https://getcomposer.org/installer | php
$ php composer.phar install
$ phpunit
