Step 1: Download DOMPDF . Paste it into application\libraries folder

सबसे पहले आपको DOMPDF लाइब्रेरी को डाउनलोड कर लेना है!और एप्लीकेशन के अंदर

लाइब्रेरी का फोल्डर है उसके अंदर इस पीडीएफ लाइब्रेरी को रख देना है

Step 2: Create a file name named Pdf.php into application\libraries folder and paste below code.

और pdf.php नाम की फाइल वहां पर बना देनी है और उस फाइल में नीचे कोड लिखा है उसे उस कोड

            को पेस्ट कर देना है!

<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');

require_once 'dompdf/autoload.inc.php';

use Dompdf\Dompdf;

class Pdf extends Dompdf
{
   public function __construct()
   {
        parent::__construct();
   }
}

?>
Step 3 : Now create a controller that renders html view to PDF.

अब एक कंट्रोलर बनाएं जो html व्यू को पीडीएफ में रेंडर करे। और पीडीएफ लाइब्रेरी को लोड करें

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

class Home extends CI_Controller {

   function __construct()
   {
        parent::__construct();
        $this->load->library('pdf');

   }

   public function index()
   {
      $data['result']=$this->Common_model->get_run("SELECT * from tbl_student ");

        //$data = 'content/dashboard';
        $this->load->view('view_class', $data);

   }

   public function pdf()
   {
        if($this->uri->segment(3))
        {



            $id = $this->uri->segment(3);
            $table='tbl_student';
        $res = $this->Common_model->getdata_one($table,$id);
            $html_content = '<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
                 ';
                 foreach ($res as $key => $value) {
                     $fname = $value['fname'];
                     $lname = $value['lname'];
                     $gender = $value['gender'];
                     $address = $value['address'];
                     $pic = $value['pic'];

                 }
            $html_content.='<div class="body"><h1 align="center">Student List</h1>
                            <div class="table-responsive">
