Class 'Smalot\PdfParser\Parser' not found - php

Question

I am trying to use Pdfparser library to parse a PDF file but I have some issues with classes inclusion.
I read the documentation but it doesn't works.
I use Windows and XAMPP.
I created a directory in /xampp/htdocs/pdf_import
I installed Composer and I've generated the /vendor/autoload.php in pdfparser-master/src
I use the code example in documentation
Example:
<?php
require 'vendor/autoload.php';
// Parse pdf file and build necessary objects.
$parser = new \Smalot\PdfParser\Parser();
$pdf = $parser->parseFile('document.pdf');
// Retrieve all pages from the pdf file.
$pages = $pdf->getPages();
// Loop over each page to extract text.
foreach ($pages as $page) {
echo $page->getText();
}
When I run the php script I obtain this error:
Fatal error: Class 'Smalot\PdfParser\Parser' not found in C:\xampp\htdocs\pdf_import\pdfparser-master\src\import.php on line 8

Somehow your path is not good for
require 'vendor/autoload.php';
Verify if autoload is actually included.
In Codeigniter3/4 be sure you put the path in your config file
$config['composer_autoload'] = 'vendor/autoload.php';
then in your controller/library
// Parse pdf file and build necessary objects.
$parser = new \Smalot\PdfParser\Parser();
$pdf = $parser->parseFile(FCPATH . 'includes/temp/' . $pdf_file);
return $pdf->getText();
