Content-Disposition ERR_INVALID_RESPONSE response

Modified on Thu, 14 Oct 2021 at 07:40 PM

When you send out a Content-Disposition header in PHP, you might end up in some situations with the wrong HTTP status code. Simply adding ",true, 200" as arguments to the header function resolves this issue.

<?php
header('Content-Disposition: attachment; filename="'.$filename.'.csv";', true, 200);
