Hello friends , I have stated using codeigniter framework for php. I would recommended codeigniter for all PHP developers.
Recently i had a task to generate PDF file in my codeigniter project ,there are many libraries like FPDF, Panda, DOM-pdf, R&OS to generate PDF documents with PHP.

I found a method to integrate R&OS pdf class file with codeigniter. I am sharing you the same.

Step 1

Download latest version of Codeigniter framework.

Step 2

Download the class files for pdf integration from here. The rar folder contains 2 folders.

1. library class files

2. fonts

Extract files under class files folder to application/libraries/

Extract fonts directory to root folder of your CI application.

Step 3

Now into final stage . Create a controller named home.php and paste the following code.

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

class Home extends CI_Controller {

 function __construct()
 {
 parent::__construct();
 }

 function index()
 {
 $this->hello_world();
 }

 function hello_world()
 {
 $this->load->library('cezpdf');

 $this->cezpdf->ezText('Hello World', 12, array('justification' => 'center'));
 $this->cezpdf->ezSetDy(-10);

 $content = 'The quick, brown fox jumps over a lazy dog. DJs flock by when MTV ax quiz prog.
 Junk MTV quiz graced by fox whelps. Bawds jog, flick quartz, vex nymphs.';

 $this->cezpdf->ezText($content, 10);

 $this->cezpdf->ezStream();
 }

 function tables()
 {
 $this->load->library('cezpdf');

 $db_data[] = array('name' => 'Jon Doe', 'phone' => '111-222-3333', 'email' => 'jdoe@someplace.com');
 $db_data[] = array('name' => 'Jane Doe', 'phone' => '222-333-4444', 'email' => 'jane.doe@something.com');
 $db_data[] = array('name' => 'Jon Smith', 'phone' => '333-444-5555', 'email' => 'jsmith@someplacepsecial.com');

 $col_names = array(
 'name' => 'Name',
 'phone' => 'Phone Number',
 'email' => 'E-mail Address'
 );

 $this->cezpdf->ezTable($db_data, $col_names, 'Contact List', array('width'=>550));
 $this->cezpdf->ezStream();
 }

}

/* End of file welcome.php */
/* Location: ./application/controllers/home.php */

You are done .

Execute the code :

http://localhost/pdf/index.php/home/index – for basic pdf creation.

http://localhost/pdf/index.php/home/tables – for table creation.

Note: In Order to write the output as a .pdf file just change $this->cezpdf->ezStream(); to $this->cezpdf->ezOutput();

Complete Code :

create a folder named pdf in root directory of codeigniter project and replace the tables function in the above controller
[ home.php ] with the following.

function tables()
{
$this->load->helper('path');
$this->load->library('cezpdf');

$this->cezpdf->ezText('Hello World', 12, array('justification' => 'center'));
$this->cezpdf->ezSetDy(-10);

$db_data[] = array('name' => 'Jon Doe', 'phone' => '111-222-3333', 'email' => 'jdoe@someplace.com');
$db_data[] = array('name' => 'Jane Doe', 'phone' => '222-333-4444', 'email' => 'jane.doe@something.com');
$db_data[] = array('name' => 'Jon Smith', 'phone' => '333-444-5555', 'email' => 'jsmith@someplacepsecial.com');

$col_names = array(
 'name' => 'Name',
 'phone' => 'Phone Number',
 'email' => 'E-mail Address'
);

$this->cezpdf->ezTable($db_data, $col_names, 'Contact List', array('width'=>550));

$directory = './pdf/';
set_realpath($directory);

$file = $directory.date('d-m-Y h:i:s').'.pdf';

$pdfcode = $this->cezpdf->ezOutput();
$fp = fopen($file,'wb');
fwrite($fp,$pdfcode);
fclose($fp);
}

You are done !
