Display PDF on browser

Question

I want to display a PDF file on browser which is store on our server. Here is my code :-

$path = $_SERVER['DOCUMENT_ROOT'].folder_name.'/resources/uploads/pdf/pdf_label_'.$order['id'].'.pdf';

$filename = 'pdf_label_'.$order['id'].'.pdf';

$file = $path;
$filename = $filename;

  header('Content-type: application/pdf');
  header('Content-Disposition: inline; filename="' . $filename . '"');
  header('Content-Transfer-Encoding: binary');
  header('Accept-Ranges: bytes');
  @readfile($file);

But it returns below output on browser :

%PDF-1.4 % 5 0 obj >stream

PDF File to show :

I am doing this on view of codeignter.

What I am doing wrong ? Please help me on this. thanks in advance

EDIT :-

Im doing something like below :

foreach($orders as $order){

$path = $_SERVER['DOCUMENT_ROOT'].folder_name.'/resources/uploads/pdf/pdf_label_'.$order['id'].'.pdf';

$filename = 'pdf_label_'.$order['id'].'.pdf';

$file = $path;
$filename = $filename;

  header('Content-type: application/pdf');
  header('Content-Disposition: inline; filename="' . $filename . '"');
  header('Content-Transfer-Encoding: binary');
  header('Accept-Ranges: bytes');
  echo file_get_contents($file);

  }

So how can I show more than one file on browser ?

Edit 2 :-

So as per the answer below I have to use phpmerger to merge multiple PDF file and display into the browser. I gone through this website http://pdfmerger.codeplex.com/ but unable to use into codeignter. Can anyone please help me to use this phpmerger inside my codeingter

Answer 1

$filePath="file path here";
$filename="file name here";
header('Content-type:application/pdf');
header('Content-disposition: inline; filename="'.$filename.'"');
header('content-Transfer-Encoding:binary');
header('Accept-Ranges:bytes');
@ readfile($filePath);

please try this code i hope it will working as i try.

Answer 2

Use exit after readfile:

$filepath = 'your-path/demo.pdf';
header('Content-Type: application/pdf');
header(sprintf("Content-disposition: inline;filename=%s", basename($filepath)));

@readfile($filepath);
exit;

ps. @ before readfile it's used to suppress errors, maybe remove it in dev mode.

Answer 3

you can use PDF Merger library to achive your goals. Here is the link to original library (outdated). Prefer myokyawhtun fork which is maintained

and a sample code will be as following

include 'PDFMerger.php';
$pdf = new PDFMerger;
$pdf->addPDF('path_to_pdf/one.pdf', '1, 3, 4')  //include file1 - pages 1,3,4
    ->addPDF('path_to_pdf/two.pdf', '1-2')      //include file2 -  pages 1 to 2
    ->addPDF('path_to_pdf/three.pdf', 'all')    //include file3 - all pages
    ->merge('browser', 'test.pdf');  // OUTPUT : make sure you choose browser mode here.

Supported modes - browser, file, download and string.

Edit : As i can see you have tagged CI you can put PDFMerger.php in applications/libraries. and load it in autoload.php or in controller

and then can use it like $this->pdfmerger->addPDF() and merge() functions.

Instead of using

@readfile($file);

Use

echo file_get_contents($file);

Or ommit the @
