PdfParser in Codeigniter

I'm trying to use the PdfParser library ( PDFparser link ) in Codeigniter, so first of all I have downloaded, unzipped and installed the library under third_party/vendor folder, additional I have downloaded, unzipped and installed the tcpdf library in the same third_party/vendor folder. Since I cannot run Composer on my remote server I have created a autoload.php file into the thir_party/vendor folder. The folder structure is now the following one:

third_party
   vendor
      autoload.php
      tecnickcom
         tcpdf
      smalot
         pdfparser
            src
               Smalot
                  PdfParser

The code into the autoload file to load all the dependencies is the following:

    $vendorDir = '../vendor';
$tcpdf_files = Array(
    'Datamatrix' => $vendorDir . '/tecnickcom/tcpdf/include/barcodes/datamatrix.php',
    'PDF417' => $vendorDir . '/tecnickcom/tcpdf/include/barcodes/pdf417.php',
    'QRcode' => $vendorDir . '/tecnickcom/tcpdf/include/barcodes/qrcode.php',
    'TCPDF' => $vendorDir . '/tecnickcom/tcpdf/tcpdf.php',
    'TCPDF2DBarcode' => $vendorDir . '/tecnickcom/tcpdf/tcpdf_barcodes_2d.php',
    'TCPDFBarcode' => $vendorDir . '/tecnickcom/tcpdf/tcpdf_barcodes_1d.php',
    'TCPDF_COLORS' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_colors.php',
    'TCPDF_FILTERS' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_filters.php',
    'TCPDF_FONTS' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_fonts.php',
    'TCPDF_FONT_DATA' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_font_data.php',
    'TCPDF_IMAGES' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_images.php',
    'TCPDF_IMPORT' => $vendorDir . '/tecnickcom/tcpdf/tcpdf_import.php',
    'TCPDF_PARSER' => $vendorDir . '/tecnickcom/tcpdf/tcpdf_parser.php',
    'TCPDF_STATIC' => $vendorDir . '/tecnickcom/tcpdf/include/tcpdf_static.php'
);

foreach ($tcpdf_files as $key => $file) {
    include_once $file;
}

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

I have created a new file into Codeigniter library folder, the file is named Pdfparser.php and its content is the following:

    defined('BASEPATH') OR exit('No direct script access allowed');

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

In the controller, I load the libray file manually with:

$this->load->library('pdfparser');

The problem is that when I try to instantiate the class with

$parser = new \Smalot\PdfParser\Parser();

I get the following error:

PHP Fatal error:  Class 'Smalot\PdfParser\Parser' not found

Any suggestion to fix this? Thanks a lot

I take it you use version control?

Install the libs via composer locally (I see you just downloaded and unzipped - that won't work). Just use the normal directory structure of vendor.

You should have a composer.json and composer.lock in your project root. After installing, composer also creates classmap files etc, which it needs in order to find your classes.

So. You can either put the vendor folder into Git (which can get a little messy depending how often you run composer commands), or you can just use a tool like scp to securely copy and deploy the vendor files into place.

Hope this helps!
