Download file using PHP

Question

I tried

$file = file_get_contents("http://my_site/wp-content/uploads/2013/04/Dev-TipsTricks.pdf", true);
echo $file;

but browser showing special characters (see image).

and I also tried

$mime_type = getMimeType($extension[1]);
ob_start();
header("Content-type: $mime_type");
header("Content-disposition: attachment; filename=$file");
ob_clean();
flush();
readfile($upload_dir['baseurl'].'/'.$file);
exit;

it downloads file when I run from localhost but on live server it is also showing special characters see image.

I also followed it file_get_contents

I also tried for pdf

header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Type: application/pdf");
header("Content-Transfer-Encoding: binary");

This is happening with all file extensions.

File path are correct & if I echo path & copy/paste in new browser tab it opens pdf & if path for docx browser allows to download.

browser following warning shows:

Warning: Cannot modify header information - headers already sent by (output started at /home/me/public_html/my_site/wp-admin/includes/template.php:1638) in /home/me/public_html/my_site/wp-admin/download.php on line 224

and this is the code in template.php

function _wp_admin_html_begin() {
    $admin_html_class = ( is_admin_bar_showing() ) ? 'wp-toolbar' : '';
?>
<!DOCTYPE html>
<!--[if IE 8]>
<html xmlns="http://www.w3.org/1999/xhtml" class="ie8<?php echo $admin_html_class;?>"<?php do_action('admin_xml_ns');?><?php language_attributes();?>>
<![endif]-->
<!--[if !(IE 8) ]><!-->
<html xmlns="http://www.w3.org/1999/xhtml" class="<?php echo $admin_html_class;?>"<?php do_action('admin_xml_ns');?><?php language_attributes(); ?>>
<!--<![endif]-->
<head>
<meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php echo get_option('blog_charset'); ?>" />
<?php
}

now i can't able to figure out where is the bug......?

You're downloading a PDF file. That's what the PDF file format looks like. — Jon Grant, May 08 '13 at 11:56
if i removed browser says header already set though there is no echo, space etc — PHP Ferrari, May 08 '13 at 11:59
this mistake occurred when the header already sent or a sign like break are printed — Alex Ruhl, May 08 '13 at 12:00
check the headers in your browser dev tools ,check that the correct content type is displayed in the response. — mpm, May 08 '13 at 12:01
@PHPFerrari Have you tried this thing $file = file_get_contents("http://siteurl/test.pdf",true); header("Content-type: application/pdf"); header("Content-disposition: attachment; filename=$file"); echo $file; — Abhishek, May 08 '13 at 12:04

header("Content-type: 'application/pdf'");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=filename.pdf"); 
    echo $content;

here you have to set the "content" .This code is working to me .As i am fetching this "content" from database which saved as .pdf document in my database.
