Storing session information
 

I am working on a plugin which builds an array and I want to keep this in their session (or, ideally, for X minutes).

calling session_start() and then $_SESSION['my_var'] = [my array] seems to not exactly have the desired effect and it is causing the page to be forceably reloaded through the Cache-Control header.

What is the best way to store this information so it doesn't have to be queried/built on every page load? I'm new to vB modification programming...

vBulletin doesn't use PHP sessions.

Which I quickly learned :)

So what method should I use to store this? Should I create another column in the sess table and just store it as serialized, or what?

If you decide to create another column you may find this helpful: [How-To] Extend and use the Session Table Effectively

Thanks.

Is that the "best" way to accomplish what I want?

Edit: Just realized it's a MEMORY table and therefore I can't store a serialized array in that table... there won't be enough room. Ideas?

Do you really need to store a whole array?

Instead of running the query on every load and then building the array, yes.
