what's 'above' session scope?

jessevitrone

I need help with storing a variable in some kinda of scope that's above session scope.

I'm going to want every user to have access to this value, and it's going to be the same for all of them.

Is there something above session scope so that I can just set it once and have everyone pick it up?

Thanks in advance,
Jesse

Constants.

// Make SOMEVAL global to your entire script, and all included functions:
define(SOMEVAL, "some value");

Not really. But you can simulate Application variables with something like this:

I'm not sure I made myself clear...let me try to explain again.

I'm used to programming in Java with JSP's and servlets. If there is something (in this case, a tree structure of nodes), that I want all users to be able to grab, I would have a servlet put something in the "servlet context" scope.

The scopes went like this:

servlet context
session
request
page

Is there anything like that in PHP?

I have a tree of nodes that defines what links a user sees on each page. I don't want to have to hit the DB and populate that tree all the time for every user, I just wanted to populate the tree once and put it in some sort of application scope that I could grab from.

Are constants the only way to do that?

Thanks,
Jesse
