Storing Array Data in CI Session

[eluser]Corey Wynsma[/eluser]
I've started using this to keep arrays in ci session vars.

Code:

// get existing array from session var (returns false if first time called)
$items = $this->session->userdata('items');

// add new $key=>$val to array
$items['some_new_key'] = "some_new_value";

// pass it back to the session var
$this->session->set_userdata('items',$items);
