How can php trigger a 404 error on nginx?

Question

This should be a simple question, but I'm having trouble with it: how can I get php to trigger a 404 error, so that the page the user sees has a true 404 header? I've seen several answers to this, but none have worked for me, maybe because I'm on nginx. I've tried:

header("Status: 404 Not Found");
header("HTTP/1.0 404 Not Found");

When I've tried each of these (with an exit() afterwards), the server has sent a 200 header.

It seems like this question has been asked in many permutations (Apache / php / sending 404s from the server level, etc) but I'm having trouble finding someone trying to do what I'm trying to do. So, apologies if this is a duplicate - if it is I won't be surprised, and please let me know.

Thank you :) - Katie

You can have a look here , php.net/manual/en/function.http-response-code.php If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code. — Shankar Narayana Damodaran

@Shankar - I'm on php 5.3 so that's a no go, looking into alternatives and what it takes to update php. — heykatieben

@Mixthos yep, just tried it and it still returns 200. Thanks though :) — heykatieben

are you sending any data before the headers and have errors turned off? — Patrick Evans

This is what worked:

Step 1, handle in php:

header("HTTP/1.0 404 Not Found");
exit();

Step 2, Remove nginx error page. I had:

error_page 404 = /404.shtml;

With the combination of those, 404s are generated as desired.

Thank you, @Barmar and @Patrick Evans for each piece of this solution! :)
