How to return a 200 ok status programmatically to ajax request in PHP?

Question

I ask this question for the comment of this answer:

https://serverfault.com/questions/104648/is-this-http-servers-issue/104679#104679

EDIT

I missed an important point,should also keep the connection not closed.

You guys can smell I'm trying to figure out how long polling actually works.

Answer 1

200 OK happens as long as nothing goes wrong. So you should always get that status as long as the HTTP request succeeds. No need to do anything special.

Answer 2

从PHP 5.4.0开始，您可以使用http_response_code() ：

<?php http_response_code(200); ?>

Answer 3

to complete hitautodestruc post, with PHP <5.4 you could also set

<?php header("HTTP/1.1 200 OK"); ?>

..but sending 200 code in any way is useless, since it is already sent by default when request completes, and if none error occurs otherwise on server-side (5xx)

maybe you are looking for something like this ?

HTTP/1.1 206    Partial Content
