Storing Array Data in CI Session

[eluser]Kyle Johnson[/eluser]
Good Morning,

I am hoping someone can help me with this small question.

I use the database version of the CI Sessions to store permissions. It is stored as an array.

Code:

$this->session->set_userdata('permissions', $permissions);

Is there a way to get specific array data from within the session?

Code:

$permissions = $this->session->userdata('permissions["shp"]'); // Example, this does not actually work!!

Currently I have to do the following:

Code:

$permissions = $this->session->userdata('permissions');
echo $permissions['shp']['add'];

This isn't a huge deal, but I would prefer not to have to load the entire permissions dataset into each page that needs permissions.

Any thoughts?
