Answer 1

I am using PDF Parser from http://pdfparser.org/

I create files application/libraries/pdf.php

class Pdf
{
    public function __construct()
    {
        require_once APPPATH."/third_party/pdfparser.php";
    }
}

Then I create file application\third_party\pdfparser.php

if (!defined('pdfparser')) {
    define('pdfparser', dirname(__FILE__) . '/');
    require(pdfparser . 'pdfparser/autoload.php');
}

Last, I include PDF Parser Library in Directory => application\third_party\pdfparser
