PHP - Forcing download a file not working

code.php

$code = $_GET["code"];
$file = 'code/'.$code.'.html';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
}

Generated URL to download the file:

http://www.example.com/code.php?code=yoursite.com_nbsp63ibrf

Well, I want to forcing download the html file, above code not working and it just preview the file at browser!

This is actually not possible. The browser can always decide on its own, if the file should be downloaded or not.

The furthest you can go is sending the content-disposition header.

unfortunately it was a encoding issue. I changed code.php encoding from UTF-8 to UTF-8 Without BOM then problem solved. Thanks for all answers and helps. I forgot that PHP header only works with UTF-8 Without BOM.

Try this

$code = $_GET["code"];
$file = $_SERVER['DOCUMENT_ROOT'] . '/code/' . $code . '.html'; // set your path from document root.
if (file_exists($file)) {
    header("Content-Type: text/html");
    header("Content-Type: application/force-download");   
    header("Content-Type: application/octet-stream");   
    header("Content-Type: application/download");     
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
}

Try changing the content type to match the file type and setting the transfer encoding to binary: 

header('Content-Transfer-Encoding: binary');
header('Content-Type: text/html');

file_exists() returns false. Change your path with document root:

$code = $_GET["code"];
$file = $_SERVER['DOCUMENT_ROOT'] . '/code/' . $code . '.html'; // set your path from document root.
if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
}
