Access array variable in session (CodeIgniter)

Question

I have an array called config. I\'m trying to echo a variable from the array in the session.

I\'ve tried:

echo $this->session->userdata(\'config[\

If you want to use the session array, use the variable, not the function:

echo $this->session->userdata['user_data']['item'];

If you want to write:

$this->session->userdata['user_data']['item'] = 'value';
$this->session->userdata['other_data']['other'] = 'value2';
$this->session->sess_write();

This allows you to edit values in array just like you do with $_SESION['user_data']['avatar'] = $avatar, with 'only' one extra line and only using CI library.
