session problem

[andreiga]

The code below saves my 'sessidsss' variable in a
sess_0987 and not in sess_123456 (which is set to 0 bytest). Why? How can I correct this?

/////////////////
session_id('123456');
session_start();
$SESSION['sessidsss'] = '0987';
//what code should be here?
session_id($SESSION['sessidsss']);
session_start();
///////////////////////

Can you explain what you are trying to do... Just a bit confuse.

I'm trying to save a user session id (e.g. 0987) in a known session id (e.g. 123456) variable so I can delete the 0987 session next time someone accesses the web site (this way even if a hacker got the session id of a user it will not be valid).

P.S. If my ideea has a flaw or there is a better way to do it please tell me.
