Where to put a "global variable" for the entire website

chakhar86, simshaun is autoloading the library. But that is not the main problem.

The main problem is the library gets loaded when the user_id is in the session or not, making database calls when they aren't needed.

The cur_user_level data is only useful when a user is logged in or you have to see the not logged user as a user_level. but that can be checked as follows

Code:

if( ! $this->session->userdata('cur_user_level'))
{
   // not logged in
}
else
{
    // do something with cur_user_level here
}
