How to get Specific Value from Session Array?

I have created a session and assigned User_id to the Session Variable. When i use print_r(); it shows me the the session variable data in an associative array but when i use foreach it gives me many error messages.

Kindly check it and guide me what i am doing wrong here.

        print_r($session_dataa= $this->session->all_userdata());

        Session dataArray ( [session_id] => 5943ecd761c336e70240b25d37b054b8 
        [ip_address] => ::1 
        [user_agent] => Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) 
        Gecko/20100101 Firefox/28.0
        [last_activity] => 1397982790
        [user_data] => [41] => )

I want to grab [user_data]=> [41] and store in student_id variable. To accomplish this i used foreach loop, but its giving me following error message.

$session_data= $this->session->all_userdata();

foreach ($session_data as $data)
{
    $student_id =   $data->user_data;
}

Severity: Notice

Message: Trying to get property of non-object

Filename: views/students.php

Line Number: 32

This is how i am assigning User_id to session data. mycontroller.php

                //[[session]]

$data['students_data']= $this->loginmodel->student_profile($currentId);     


$this->load->library('session');
   $this->session->set_userdata($currentId);

You are not associating current_id with any variable, The Correct way to assign Values to a session variable is given below;

Controller

$this->load->library('session');

$this->session->set_userdata(array(
                             'currentId' =>$current_id                           
                            ));

View 

$student_id                   = $this->session->userdata('currentId');

To get your session variable simply do

$this->session->userdata('user_data');

When you access a session variable using the session class like this it will automatically check to see if its set or not so you won't get any errors.

How about

$student_id= $session_data['user_data'];

Try this

$session_data= $this->session->all_userdata();

$student_id =   $session_data[user_data];

OR

$session_data= $this->session->all_userdata();

foreach ($session_data as $data)
{
    $student_id =   $data[user_data];
}
