это код PDF Generator

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 
class Createpdf extends CI_Controller { 

    function __construct() 
    { 
     parent::__construct(); 
     $this->load->library("Pdf"); 
    } 

    public function create_pdf() { 

    // create new PDF document 
    $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);  

    // set document information 
    $pdf->SetCreator(PDF_CREATOR); 
    $pdf->SetAuthor('lakmini'); 
    $pdf->SetTitle('RCJ CONSTRUCTIONS'); 
    $pdf->SetSubject('TCPDF Tutorial'); 
    $pdf->SetKeywords('TCPDF, PDF, example, test, guide'); 

    // set default header data 
    $pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING, array(0,64,255), array(0,64,128)); 
    $pdf->setFooterData(array(0,64,0), array(0,64,128)); 

    // set header and footer fonts 
    $pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); 
    $pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); 

    // set default monospaced font 
    $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); 

    // set margins 
    $pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); 
    $pdf->SetHeaderMargin(PDF_MARGIN_HEADER); 
    $pdf->SetFooterMargin(PDF_MARGIN_FOOTER);  

    // set auto page breaks 
    $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); 

    // set image scale factor 
    $pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

    // set some language-dependent strings (optional) 
    if (@file_exists(dirname(__FILE__).'/lang/eng.php')) { 
     require_once(dirname(__FILE__).'/lang/eng.php'); 
     $pdf->setLanguageArray($l); 
    } 

    // ---------------------------------------------------------  

    // set default font subsetting mode 
    $pdf->setFontSubsetting(true); 

    // Set font 
    // dejavusans is a UTF-8 Unicode font, if you only need to 
    // print standard ASCII chars, you can use core fonts like 
    // helvetica or times to reduce file size. 
    $pdf->SetFont('dejavusans', '', 14, '', true); 

    // Add a page 
    // This method has several options, check the source code documentation for more information. 
    $pdf->AddPage(); 

    // set text shadow effect 
    $pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));  

    // Set some content to print 
    $html = <<<EOD 
    <h1> this is my first pdf </h1> 
EOD; 
    // Print text using writeHTMLCell() 
    $pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true); 

    // ---------------------------------------------------------  

    // Close and output PDF document 
    // This method has several options, check the source code documentation for more information.

У меня есть код библиотеки MPDF сначала вы должны загрузить CodeIgniter ссылку библиотеки MPDF (http://mpdf1.com/repos/MPDF60.zip) с последней версии, затем извлечение zip-файла и вставку библиотеки MPDF на пути приложений/библиотек к использованию ниже кода -

<a href="<?php echo base_url(); ?>controllerName/PDFFile(method name)">Generate PDF</a> 

PDFFile Метод -

public function PDFFile() 
    { 
     $data['results'] = $this->common_model->federationPDF_file(); 
     // it will fetch data from database 

      $html = $this->load->view('Print_pdf',$data,true); // here we will pass view file name that contain table data 

      $this->load->library('MPDF/mpdf'); 
      $mpdf=new mPDF('utf-8','A4', '12', '', 10, 10, 10, 10, 9, 9); 
      $mpdf->useOnlyCoreFonts = true; 
      $mpdf->SetProtection(array('print')); 
      $mpdf->SetTitle(SITE_NAME); 
      $mpdf->SetAuthor(SITE_NAME); 
      $mpdf->SetCreator(SITE_NAME); 
      $mpdf->SetDisplayMode('fullpage'); 
      $mpdf->WriteHTML($stylesheet,1); 

      $search = array("<div class=\"row-fluid\">", "<div class=\"span6\">"); 
      $replace = array("<div style='width: 100%;'>", "<div style='width: 100%; float: left;'>"); 
      $html = str_replace($search, $replace, $html); 
      $name = "PDF File"; // file name 
      $mpdf->WriteHTML($html); 
      $mpdf->Output($name, 'D'); 
      exit; 
    } 

Мой Print_pdf Просмотр файла -

<!DOCTYPE html> 
<html> 
<head> 
    <title>PDF File</title> 
</head> 
<body> 
<div align="center"> 
</div> 
<h2 align="center">Table Data</h2> 
    <table border="1" align="center" cellpadding="1" cellspacing="0"> 
<thead> 
    <tr> 
     <td><b>S.No.</b></td> 
     <td><b>First Name </b></td> 
     <td><b>Last Name </b></td> 
     <td><b>Mobile</b></td> 
     <td><b>Address</b></td> 
    </tr> 
</thead> 
<tbody> 
    <?php $count = 1; 
    foreach($results as $s) 
     { ?> 
     <tr> 
      <td><?php echo $count; ?></td> 
      <td><?php echo $s['fname']; ?></td> 
      <td><?php echo $s['lname']; ?></td> 
      <td><?php echo $s['mobile']; ?></td> 
      <td><?php echo $s['address']; ?></td> 
     </tr> 
    <?php $count++; } ?> 
</tbody> 
</table> 

</body>
