Downloading show garbage on the screen

I have PHP code for downloading pdf files from mysql database. The code is working fine in firefox mozilla and google chrome but not in IE 10, it show garbage in the screen. I have debugged the code with some headers utilities to examine the headers request, it appear the headers is not sending back to the user agent (IE browser) it just blank.

my php code

Code:

<?php
ob_start();
$company =$_GET['company'];
if(isset($_GET['id']))
{
  $id = intval($_GET['id']);
  if($id <= 0)
  {
    die('The ID is invalid!');
  }
  else
  {
    $dbLink = new mysqli('localhost', 'sqldata', 'sqldata', 'balhaf');
    if(mysqli_connect_errno())
    {
      die("MySQL connection failed: ". mysqli_connect_error());
    }
    $query = "SELECT mime, name, size, data FROM $company WHERE id = $id";
    $result = $dbLink->query($query);
    if($result)
    {
      if($result->num_rows == 1) {
        $row = mysqli_fetch_assoc($result);
        $size = $row['size'];
        $filename = $row['name'];
        $data = $row['data'];
        $mime = $row['mime'];
        ini_get('zlib.output_compression');
        ini_set('zlib.output_compression', 'Off');
        header('Content-Type: application/pdf');
        while (@ob_end_clean());
        header('Content-Disposition: attachment; filename='.($filename));
        header('Content-Length:'.($size));
        echo $data;
        exit();
      }
      else
      {
        echo 'Error! No image exists with that ID.';
      }
      mysqli_free_result($result);
    }
    else
    {
      echo "Error! Query failed: <pre>{$dbLink->error}</pre>";
    }
    mysqli_close($dbLink);
  }
}
else
{
  echo 'Error! No ID was passed.';
}
?>

xdg-settings

XDG-SETTINGS(1) 						xdg-settings Manual						   XDG-SETTINGS(1)

NAME

       xdg-settings - get various settings from the desktop environment

SYNOPSIS

       xdg-settings {get | check | set} {property} [subproperty] [value]

       xdg-settings {--help | --list | --manual | --version}

DESCRIPTION

       xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and
       default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop
       environment's libraries (which would use the settings natively).

       xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root.

OPTIONS

       --help
	   Show command synopsis.

       --list
	   List all properties xdg-settings knows about.

       --manual
	   Show this manual page.

       --version
	   Show the xdg-utils version information.

PROPERTIES

       When using xdg-settings to get, check or set a destkop setting, properties and possibly sub-properties are used to specify the setting to
       be changed.

       Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as
       default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided
       in a sub-property.

EXIT CODES

       An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:

       1
	   Error in command line syntax.

       2
	   One of the files passed on the command line did not exist.

       3
	   A required tool could not be found.

       4
	   The action failed.

EXAMPLES

       Get the desktop file name of the current default web browser

		   xdg-settings get default-web-browser

       Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current
       value (if only some of the underlying settings actually reflect that value)

		   xdg-settings check default-web-browser firefox.desktop

       Set the default web browser to google-chrome.desktop

		   xdg-settings set default-web-browser google-chrome.desktop

       Set the default mailto URL scheme handler to be evolution.desktop

		   xdg-settings set default-url-scheme-handler mailto evolution.desktop
