I'm using library PDFparser (https://github.com/smalot/pdfparser) to convert PDF file to text.

When I try to convert a file on a local web-server, it parses OK. When I try to convert a file on remote web-server, it fails with the following error: TCPDF_PARSER ERROR: Invalid object reference: Array.

I couldn't find a proper solution in the bug-tracker of a library, although there is exist the similar question (it didn't solved for two years).

How can I avoid this error? Or should I use another library for converting pdf to text (which)?

I am using it straight as mentioned in documentation:

use Smalot\PdfParser\Parser;

$this->parser = new Parser;

if (file_exists($full_path) && !is_dir($full_path)) {
    $paper->text = $this->parser->parseFile($full_path)->getText();
}

WTF dude! How can anyone know with no code? – AbraCadaver Feb 04 '18 at 03:07
@AbraCadaver, added code, sorry :) – Александр Чи Feb 04 '18 at 03:40
You need to make sure your PDF is 1.4 or lower. This means roughly Acrobat 5 compatible. – hcoat Feb 04 '18 at 03:42
@hcoat, but on local web-server it converts even PDF1.7. On remote server - it fails on PDF1.3! (and on 1.4 and on 1.7) – Александр Чи Feb 04 '18 at 03:43
@АлександрЧи That is odd. I guess I would suggest using composer to upgrade packages or reinstall. Also make sure you are running the same version of PHP on both machines with the same extensions. – hcoat Feb 04 '18 at 03:49
Do you check if the PDF is not corrupted? A site to verify: https://www.pdf-online.com/osa/validate.aspx – LuizMoratelli May 15 '19 at 14:45
The fix on this page was useful for me with a case like yours: https://github.com/smalot/pdfparser/issues/86 – Natxet Jul 30 '20 at 10:10
