Multiple sessions in one instance using PHP?

Question

I have a project where I would like to create two session cookies in one browser. The first session would be to uniquely identify a person, the second would be to share even

Answer 1

Where is the "valueSharedBetweenUsers" coming from? Is it a constant or database entry?

Either way, it wouldn't make sense to create one session per group. You should instead be giving each user a unique session per user; with your "shared" attribute as a session attribute for each individual.

So start the unique session then just do

Now everyone has a session with a unique sessionID and a common value 'session'.

(Obviously if you need to change this attribute later you'll have to do it separately for each authed individual)
