Using PdfParser without Composer #117

apmuthu · 2016-09-26T09:44:42Z

Alternative Autoloader built in

Since v0.18.2 you don't need to do the following steps to use PDFParser without Composer. Please check https://github.com/smalot/pdfparser#install for further information on our alternative autoloader.

❗ Outdated

Last checked in 2020

Updated file: vendor-autoload.zip - See #117 (comment)

The ../vendor/autoload.php gets generated when we use composer and we include it in our scripts for PdfParser access. If we wish to freeze our install and manage it without using Composer, this said file can be created to have the following:

<?php
/**
 * this file acts as vendor/autoload.php

$prerequisites = array();

/**

$prerequisites['pdfparser'] = array (

We can now create a test.php in the deployment folder (pdfdemos here) with:

<?php
include "../vendor/autoload.php";

$directory = getcwd();
$file = 'INV001.pdf';
$fullfile = $directory . '/' . $file;
$content = '';
$out = '';
$parser = new \Smalot\PdfParser\Parser();

$document = $parser->parseFile($fullfile);
$pages    = $document->getPages();
$page     = $pages[0];
$content  = $page->getText();
$out      = $content;
echo '<pre>' . $out . '</pre>';

EDIT 1 by k00ni: added updated PHP code from @ndmax. Also removed tecnickcom/tcpdf (not needed anymore) and added code highlighting.

The text was updated successfully, but these errors were encountered:

rajeshgozoom · 2017-11-08T14:14:25Z

Wow Man, You are great, that really awesome and worked for me...

Thanks a TON!!!

kaustavdey · 2018-03-06T23:02:49Z

Sir its simply great. Can you also help to install Tesseract OCR for php without composer?

apmuthu · 2018-03-07T11:03:53Z

I have not used this wrapper: Tesseract OCR for PHP. If you succeed in deploying it, do let us know what issues crop up.

I have only used the compiled version of Tesseract OCR.

yousaf50 · 2018-08-05T04:00:51Z

WOW sweet work ..love from pakistan.

federicovilla · 2018-10-26T08:14:45Z

Great hint apmuthu...this solve my issue since I cannot run composer on my remote server.
I'm trying to use your modified installation and autoload into a Codeigniter site...so I installed all files and autoload into the third_party folder.
I have created a library with the follpwing code
class Pdfparser { function __construct() { require_once '/third_party/vendor/autoload.php'; } }

after that I've added this method into the controller:
function file_pdf_parser($file){ $parser = new \Smalot\PdfParser\Parser(); $pdf = $parser->parseFile($file); $text = $pdf->getText(); return $text; }

but when I try to execute the method I get the following error:
[26-Oct-2018 08:18:58 UTC] PHP Fatal error: Class 'Smalot\PdfParser\Parser' not found in /home/gavsit/public_html/application/controllers/adm/Files.php on line 324

Any hint to solve this? Thanks a lot

apmuthu · 2018-10-31T01:11:56Z

Make the path to the autoload relative like (or completely absolute with full linux path):

class Pdfparser {
    function __construct() {
        require_once ('third_party/vendor/autoload.php');
    }
 }

doganoo · 2018-10-31T06:08:42Z

What exactly you mean by „freeze“? Composer doesn’t update any files until you run „composer update“ and you don’t change your composer.json and/or composer.lock files.

Therefore, just run “composer update” on your instance and enjoy?!

apmuthu · 2018-11-07T16:38:44Z

For those who cannot use composer for whatever reason (offline, stability, unfamiliarity, etc), this thread lists an alternative.

ndmax · 2019-03-26T11:22:39Z

I really do wish this was baked into pdfparser (and other projects that assume Composer). I don't use Composer, and don't want to add yet another dependency/package manager for one project submodule. Composer isn't installed in my production environment.

I don't mean to suggest ejecting Composer (it's a common standard and super easy if you're already using it), but simply including an installation procedure that doesn't require Composer. An example would be the DOMPDF project.

In any case, thanks @apmuthu for this post.

ndmax · 2019-03-27T01:03:51Z

Also: Object.php is now PDFObject.php

apmuthu · 2019-03-27T01:14:25Z

@ndmax: Thanks for the info and glad for the +1 composer-less implementation initiative.

Yes, you're right, the renaming of the file will now require, in the code snippet above, the replacement of the line:

include_once  $vendorDir . "/smalot/pdfparser/src/Smalot/PdfParser/Object.php";

with

include_once  $vendorDir . "/smalot/pdfparser/src/Smalot/PdfParser/PDFObject.php";

Stands corrected in the opening post above.

WillRun4Cake · 2020-05-04T19:00:54Z

Apmuthu, thank you. This thread was very helpful.
Below I have attached an example for doing this without Composer. This should be extracted to the /var/www/html directory or public_html directory.

Three additional things to mention:

I just cloned the master branch on May 3, 2020 and the Object.php has still not been renamed to PDFObject.php
Make sure you have the php-mbstring extension installed, e.g.
sudo apt-get install php-mbstring
yum install php-mbstring
You may also need to enable in php.ini:
extension=mbstring

Examples:

example.zip
example.tar.gz

apmuthu · 2020-05-04T21:08:36Z

Thanks Joseph. Stands corrected.

Duplicates #279

ndmax · 2020-07-28T18:17:18Z

For those who have been manually implementing w/o Composer, the following two new includes are now required:
/RawData/FilterHelper.php
/RawData/RawDataParser.php

k00ni · 2020-07-29T09:28:21Z

Because this issue seems interesting for some people, we could pin it. Furthermore, information like the last of @ndmax should be merged into the initial post so that new people find them quickly without the need to scroll through the whole issue.

What do you think?

CC @j0k3r

j0k3r · 2020-07-29T09:56:25Z

@k00ni I agree. I've pinned the issue. Can you update the initial post?

k00ni · 2020-07-29T10:00:32Z

@ndmax, @apmuthu and others: I would like to keep the initial post up-to-date. Can you tell me, what needs to be changed?

As far as I saw, these files need to be added:

/RawData/FilterHelper.php
/RawData/RawDataParser.php

ndmax · 2020-07-29T11:04:24Z

Thanks @k00ni and @j0k3r. Relative to the project directory, I think a current full list of includes would look something like this:

/Parser.php
/Document.php
/Header.php
/PDFObject.php
/Element.php
/Encoding.php
/Font.php
/Page.php
/Pages.php
/Element/ElementArray.php
/Element/ElementBoolean.php
/Element/ElementString.php
/Element/ElementDate.php
/Element/ElementHexa.php
/Element/ElementMissing.php
/Element/ElementName.php
/Element/ElementNull.php
/Element/ElementNumeric.php
/Element/ElementStruct.php
/Element/ElementXRef.php
/Encoding/StandardEncoding.php
/Encoding/ISOLatin1Encoding.php
/Encoding/ISOLatin9Encoding.php
/Encoding/MacRomanEncoding.php
/Encoding/WinAnsiEncoding.php
/Font/FontCIDFontType0.php
/Font/FontCIDFontType2.php
/Font/FontTrueType.php
/Font/FontType0.php
/Font/FontType1.php
/RawData/FilterHelper.php
/RawData/RawDataParser.php
/XObject/Form.php
/XObject/Image.php

k00ni · 2020-08-13T10:27:32Z

Sorry for the late response @ndmax. I hope its not too much of an ask: can you put your file list (as includes) in the code from @apmuthu so I can copy it directly?

apmuthu · 2020-08-13T10:53:48Z

vendor-autoload.zip
The order of the files given by @ndmax is correct and the ../vendor/autoload.php file stands attached herewith.

ndmax · 2020-08-16T13:34:12Z

Sorry I missed this @k00ni and thanks @apmuthu for posting up a drop-in file.

For what it's worth, I implement pdfparser as part of a larger class responsible for all PDF-related functionality. Here's how the pdfparser component get's wired up (trimmed up a bit for simplicity):

<?php

  $prerequisites = array();

  $pdfparser = '/host/path/to/pdfparser';

  $prerequisites['pdfparser'] = array (
    $pdfparser.'/Parser.php',
    $pdfparser.'/Document.php',
    $pdfparser.'/Header.php',
    $pdfparser.'/PDFObject.php',
    $pdfparser.'/Element.php',
    $pdfparser.'/Encoding.php',
    $pdfparser.'/Font.php',
    $pdfparser.'/Page.php',
    $pdfparser.'/Pages.php',
    $pdfparser.'/Element/ElementArray.php',
    $pdfparser.'/Element/ElementBoolean.php',
    $pdfparser.'/Element/ElementString.php',
    $pdfparser.'/Element/ElementDate.php',
    $pdfparser.'/Element/ElementHexa.php',
    $pdfparser.'/Element/ElementMissing.php',
    $pdfparser.'/Element/ElementName.php',
    $pdfparser.'/Element/ElementNull.php',
    $pdfparser.'/Element/ElementNumeric.php',
    $pdfparser.'/Element/ElementStruct.php',
    $pdfparser.'/Element/ElementXRef.php',
    $pdfparser.'/Encoding/StandardEncoding.php',
    $pdfparser.'/Encoding/ISOLatin1Encoding.php',
    $pdfparser.'/Encoding/ISOLatin9Encoding.php',
    $pdfparser.'/Encoding/MacRomanEncoding.php',
    $pdfparser.'/Encoding/WinAnsiEncoding.php',
    $pdfparser.'/Font/FontCIDFontType0.php',
    $pdfparser.'/Font/FontCIDFontType2.php',
    $pdfparser.'/Font/FontTrueType.php',
    $pdfparser.'/Font/FontType0.php',
    $pdfparser.'/Font/FontType1.php',
    $pdfparser.'/RawData/FilterHelper.php',
    $pdfparser.'/RawData/RawDataParser.php',
    $pdfparser.'/XObject/Form.php',
    $pdfparser.'/XObject/Image.php'
  );

  foreach($prerequisites as $project => $includes) {
    foreach($includes as $mapping => $file) {
      require_once $file;
    }
  }

?>

k00ni · 2020-08-17T07:58:35Z

OK, i adapted @apmuthu's initial post with code from @ndmax. Hope I didn't miss something. AFAIK these classes in the use section are not needed (and not available) anymore (like Datamatrix), because I removed tecnickcom/tcpdf a while ago.

WillRun4Cake · 2020-11-01T02:52:36Z

I have updated my example for using PdfParser when Composer is not an option.

It now aligns with the v0.17.1 release and includes 3 new files:
RawData/FilterHelper.php
RawData/RawDataParser.php
Encoding/PostScriptGlyphs.php

You can download, extract and copy this to your webroot directory to start using PdfParser immediately.
Follow the example code in text_extractor_example.php to invoke PdfParser.
Only the classes/ directory is required. The following files are for example and may be deleted:
readme.md
test.pdf (replace with your own pdf)
text_extractor_example.php (example code)
index.php (use your existing index.php)

This should be placed in the /var/www/html directory or public_html webroot directory, as applicable.

Two additional things to mention:
1. Make sure you have the php-mbstring extension installed, e.g.
sudo apt-get install php-mbstring
OR
yum install php-mbstring
2. You may also need to enable in php.ini:
extension=mbstring

PdfParser Team, I noticed that Object.php was renamed to PDFObject.php. Thanks for making this fix.

example.tar.gz

WillRun4Cake · 2020-11-01T02:58:12Z

I have attached an updated set of example files to use the new files: /RawData/FilterHelper.php /RawData/RawDataParser.php This should now align with v0.17.1. This took quite some time to get around to doing, but hopefully this will be helpful to someone. Thanks for including me in the email list.

Hello Everyone,

If you're still implementing this project manually and you're suddenly getting 500s with Fatal error: Uncaught Error: Class 'Smalot\PdfParser\Config' not found there's a new include:

'/Config.php'

@apmuthu @k00ni it might be worth adding $pdfparser.'/Config.php', to the code snippet for manual include.

k00ni · 2021-01-18T08:23:24Z

@ndmax thank you for the hint. I updated the initial post accordingly.

In my opinion Composer should be the way to go, but I acknowledge that there is also the need to use other ways. Therefore my proposal:

create a new file in root folder, named autoload.php or something like that
move includes from initial post into that file
close this issue with a notice about that file

Advantages:

Its easier for developers to just require this file and have everything they need (no need to parse this issue again and again when there are upgrades)
We can extend this file by using pull requests, which makes it easier to keep it up to date than using this issue (and copy paste).

What do you think?

CC @j0k3r @apmuthu

j0k3r · 2021-01-18T13:15:13Z

That might be a good idea. We should warm people that the mbstring extension will then be required because the Symfony polyfill won't be installed (required in composer.json).
Following adding that new autoload.php file, we should also add a custom test to ensure it is working as expected. So the test will fail if we add a new file and forgot to update the autoload.php file.

ndmax · 2021-01-18T21:20:48Z

I think it's a good approach @k00ni. It eliminates the cat-and-mouse for the few who incorporate manually, without disrupting the majority who install with Composer. Comment instructions at the top of autoload.php and a brief reference to install options in README.md would point everyone down the right path.

apmuthu · 2021-01-19T02:27:51Z

The said autoload.php should not be overwritten by any unintended composer update / unzip.

A file called autoload_standalone.php that gets included if present may be the answer.

In order not to break dependencies of certain missing libraries / files, the optional set of includes can be commented out and enabled as needed by the end user.

Notes in it as applicable to certain commits onwards would be useful to use the appropriate version.

k00ni · 2021-02-09T10:44:22Z

There is a new pull request which may help in the future. Once it passes there should be no more manual work required to use PDFParser without Composer.

Feedback is appreciated at #388

DionardoMarques · 2023-01-12T15:38:17Z

Thanks a lot, it worked perfectly! Regards from Brazil.
