How to download a dynamically generated file and make the location of this page?

I have a file dynamically created with some text, you need to download it, and then do header("Location").
I do not understand how to do this, because I send the browser a header:

header('Content-disposition: attachment; filename=test.txt');
header('Content-type: text/plain');
echo "Что-то пишем в файл";

header('Location: ' . $_SERVER["REQUEST_URI"]);

And of course it gives an error, because the text is already being output, and after that we still send headers
. You can somehow fix this or offer alternative options (I don’t really want to store the file on the server)

Your problem is that you give the UTF-8 encoding, and place the text in 1251 encoding .
1. kruslan 's answer - change the encoding to UTF-8 of the received text
2. header('Content-Type: text/html; charset= windows-1251')
somewhere at the very beginning of the code before any text is printed.

Grigory Vasilkov , in general, did it through js, but I don’t know how good it is, I just don’t see any more options, because unique values ​​​​are generated, and then go to hash, after which I do a js hook

<a download="password.txt" id="data" href="#" style="display: none;"></a>
  var type = "data:application/octet-stream;base64, ";
  var text = "Данные для авторизации \\r\\nЛогин: ' . $login . ' \\r\\nПароль: ' . $password . '";
  var base = btoa(unescape(encodeURIComponent(text)));
  var res = type + base;
  document.getElementById("data").href = res;

unfortunately only javascript. you can't send a file and then redirect it. the return of the file is code 200 - everything is ok. and the redirect is 301
action logic code - try to do it like on megashare mine or some such well-known exchanger that gives the file in its own way, I suppose it somehow transfers it piece by piece to javascript via a websocket, probably, and then connects the pieces of the file already on the client and download instantly. and after that instant download - redirect person
