<?php
	session_start();
        $sid1 = session_id();
	session_unset();
	session_destroy();

	// ...and create new one
	session_start();
        $sid2 = session_id();
        if ($sid1 === $sid2) {
          print 'equals';
        } else {
          print 'doesn\'t equal';
        }
?>

This prints 'equals'...is it OK ? I think that session id should change between two different sessions...

Confirming.

Looks like sessions are started only once. This issue is even with session_write_close(). session_start() after any session-closing commands simply does not work. It would be better if it reloaded session (or created new, depending on was it destroyed or saved). It is a pain to redirect the page to self to get session data again.

Hope it'll be fixed. Sometimes it is needed to unlock session/then access it again.

Of course it doesn't change..it's already set in the cookie.
This is a feature actually..

I don't use cookies...my session.use_cookies in php.ini is set to off. My answer is if session_start() called after session_destroy() should generate new session id or same one? Look at the code again to understnd what I mean.
