PHP send both http 1.0 and 1.1 headers

I see somewhere people doing something like:

<?php
header('HTTP/1.0 200 OK');
header('HTTP/1.1 200 OK');
?>

What's the purpose of this? Seems the second one will always overwrite the first header? Or is this because if some clients doesn't support http 1.1 so they can still receive a 1.0 header?

There is no purpose to this. Only one HTTP status line can be sent to the client.

The default is to send 200 OK anyway, so unless you're overriding a previous status line (which would be strange), then both lines are pointless.

If you are using PHP 5.4+, you should use http_response_code() to set the status code anyway. Leave the protocol implementation up to the web server.
