phpBB way of adding session vars

[MasterZ]

If I want to add a new var to the user session just to be stored for a couple of pages, how do I do this?

Currently I'm using $_SESSION['var_name'] but there has to be a phpBB method for doing this. I need to set the value, get the value, and delete the key. Any ideas? I keep searching phpBB docs but no luck so far.

What exactly are you storing?

To be honest, it's either stored in a db table or cached..

Storing some information for the openid authentication before the user gets sent to the openid provider.

So do I need to create a new table to store information then? Or just leave the session_start() in there for now

If I do store the information in a new table I need some way to track the session id to make sure I pull out information from the same session that it gets saved to. How do I get the session id?

Or does someone else have a better way to do this?

Since this is going to require an extra table to be created in the DB I think I'm just going to leave it as is for now. If the MOD validation team complains then I will make the new table.
