How to setup redirect after 403 Forbidden header in php?

Question

PHP

Hello. I wanted to do this: when trying to request a specific page, check if the user is not authorized - send a 403 code and redirect, for example, to the main one.
What do I do:

header("HTTP/1.1 403 Forbidden");
header("Location: http://" . $_SERVER['HTTP_HOST']);
exit();

But when viewed in a browser, I see the following answer:
Status Code:302 Found
It turns out that 403 does not shine anywhere .. The question is why?

Answer 1

What if you try it?

header("HTTP/1.1 403 Forbidden");
header("Location: http://" . $_SERVER['HTTP_HOST'], TRUE, 403);
exit();
