Maybe all the optimizations that came with PHP 7 will make this point obsolete. However I don’t have strict evidence at the moment. The only depedency tool you use is Composer.ĬLI tools, especially these written in C/C++, might be faster and use less memory. They are a lot easier to set up and update. Native PHP libraries should work independently from the host environment. There are a couple of basic considerations. In fact, these two libraries are wrappers to a wrapper, since poppler-utils are just a collection of CLI wrappers for the Poppler C++ library 😉 Which to pick? Native or CLI? Also, this library is not very convenient as it forces you to choose an output directory for a file (it does not return processed data as string).

ncjoes/poppler-php: a library supposed to wrap all poppler-utils, but at the moment pdftotext is still unsupported.

The library does not wrap additional input arguments, so you have to specify them manually.

It requires an input PDF to exist in the file system.

spatie/pdf-to-text only allows to extract text from a PDF.

Poppler has several PHP wrapper libraries: Imagemagick and Ghostscript are the basis for spatie/pdf-to-image wrapper. PDFBox CLI can be accessed via schmengler/PdfBox. Wrappersįor pdftk, check out this library: mikehaertl/php-pdftk. At the time of writing, there are no native PHP libraries to render a PDF. You can do it with pdftocairo from Poppler, or use ImageMagick’s convert. Sometimes you might want to create a PNG or JPEG screenshot of a document. You can use it to extract JavaScript too. Also, pdfinfo provides comprehensive information about a file, like page format, encryption type etc. For example, the pdftotext tool gives a lot of control over the plain text dump – you can even preserve a proper document layout while rendering, or crop the document to a specified region.

This C++ library can be accessed via dedicated CLI tools – poppler-utils, which we can run from PHP.

Later I discovered the Poppler library, which is said to fully support the ISO 32000-1 standard for PDF. However, in the PHP world we can only access a CLI wrapper for that library which has a limited set of options. It is written in Java and, as I described before, it offers some very nice features. The need to extract plain text from a document led me to the Apache PDFBox library.

The only thing that’s missing is a text extraction feature. It supports all PDF formats unlike FPDI library. I used it to join separate documents into one, apply watermarks and extract basic metadata, like a number of pages. The first command-line tool I played with was pdftk. We decided to switch to another tool, pdftk, which is described below.

And that’s what the bug report was about.

To support higher document versions, you have to buy a full library.

The problem is that the free version of FPDI supports only PDF version 1.4 and below. The module received a PDF, parsed it using FPDI, generated a watermark with FPDF and stamped it over all pages. I got familiar with this library when I received a bug report for a watermarking module in some e-book system. They can differ especially in terms of processing corrupted files. You can compare both libraries by parsing different documents. This parser draws less interest than the first one, though the author has over 15 years of experience handling PDFs. This is a library made by the creator of TCPDF, a well-known library generating PDF files. Smalot/pdfparser has commercial support from Actualys. print_r ( $document -> getDetails ()) // text dump echo $document -> getText () $parser = new Smalot\PdfParser\Parser () $document = $parser -> parseFile ( 'test.pdf' ) // creator, date of creation, number of pages etc. You can test the library at its demo page. However, encrypted files are not yet supported. It allows you to extract metadata and plain text from a document along with other objects (images, fonts). The library is convenient as it supports both parsing an existing file or a string with PDF data. It parses a PDF file into an array of document objects which is further processed to get what we need. There is an interesting library called smalot/pdfparser. Native PHP librariesĪgain, we will start from checking if there are any PHP libraries to manipulate PDF files without depending on external binary tools. Today we will browse possibilities to read and edit existing PDF files. Back then, the choice was not easy and we had a lot of criteria to consider while picking the best tool. In the previous article I described several tools that can be used together with PHP to create PDF files. To make a JPEG or PNG screenshot of a PDF, use ImageMagick or pdftocairo.

To join or split PDF files, encrypt them or apply watermarks, use pdftk. For advanced options, try pdftotext and pdfinfo from Poppler. TL DR For simple PDF text and metadata extraction, use pdfparser.
