I am writing some server to server software that needs to maintain state.
When I say server to server I mean that the client is not a browser, it
is another PHP server (as if that wasn't obvious).
The word "server" has lots of meanings. What do you mean exactly? If you
are connecting to a remote server using HTTP, it doesn't matter who you
are: the mechanism is exactly the same.
This is the server (pseudocode). Forget the transport mechanism, imagine
that any function can be called remotely.
You are making a rather curious assumption but...
The problem seems to be that session_start on the server side is called
at the top of the script, and there is no way to change the session_id
midstream.
.... this works for me:
<?php
session_id('A');
session_start();
$_SESSION['who_am_i'] = 'I am session A';
session_write_close();
session_id('B');
session_start();
$_SESSION['who_am_i'] = 'I am session B';
session_write_close();
session_id('A');
session_start();
echo $_SESSION['who_am_i'] . "\n";
session_write_close();
session_id('B');
session_start();
echo $_SESSION['who_am_i'] . "\n";
session_write_close();
?>
You need to set session.use_cookies to 0 in your php.ini (or use @ to hide
warnings).
