How to send a file to the browser for download?

Question

PHP

There is a link to the video: https: //api2.musical.ly/aweme/v1/playwm/ ?video_id = ... I have the following file with this code:

download.php

<?php

if (isset($_GET['video']))
{
    $ch = curl_init($_GET['video']);

    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1)
    curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);

    curl_close($ch);

    header("Content-type: application/octet-stream");
    header("Content-Disposition: attachment; filename=video.mp4");
    echo $output;

    die();
}

I am trying to download a file like this:

https://example.com/download.php?video=https://api2.musical.ly/aweme/v1/playwm/?video_id=v09044530000bqsiqd8lths38b053nrg

A broken file with a weight of 1kb is downloaded, but if you pass it the final link that after the redirect, the file is saved correctly.

The question is how to display a dialog box prompting you to save the file when you click on the link?
It seems FOLLOWLOCATION indicated, but I don’t understand what the problem is.
