What is the default response code of the php header function

Question

When I redirect users using the header() function, only passing the first argument, what response code will be send?

I had header('Location: https://' . $_SERVER['HTTP_HOST']); set for some time on old pages, and now I'm curious if that redirect might have been cached by browsers.

if you use header("Location" you should get a 302. You can read this in the docs already. Or you could have tested it about as quickly as writing a question — ADyson

It will send a 302 (temporary redirect) if you send a Location header and don't specify otherwise. From the manual:

The second special case is the "Location:" header. Not only does it send this header back to the browser, but it also returns a REDIRECT (302) status code to the browser unless the 201 or a 3xx status code has already been set.

Edit: So, to answer your follow-up query: no, this should not have been cached.

There are two special-case header calls. The first is a header that starts with the string "HTTP/" (case is not significant), which will be used to figure out the HTTP status code to send. For example, if you have configured Apache to use a PHP script to handle requests for missing files (using the ErrorDocument directive), you may want to make sure that your script generates the proper status code.

for more details , please check http://php.net/manual/en/function.header.php
