How to get data from an array in array inside session in codeigniter?

Question

I want to get data from an array in array inside of session. i want to get the rule1 of each array. But when i print $y like in the code below, it doesn't print anything

$this->session->userdata['namearray'];

this is print_r of the session

Array (
        [0] => stdClass Object
        (
            [class] =>array (
                   [0] => stdClass Object
                   (
                     [rule1] =>a

                    )
                   [1] => stdClass Object
                   (
                     [rule1] =>b

                    )
             )
         [1] => stdClass Object
        (
            [class] =>array (
                   [0] => stdClass Object
                   (
                     [rule1] =>c

                    )
                   [1] => stdClass Object
                   (
                     [rule1] =>d

                    )
             )

    )

foreach ($nameArray as $y){ 
                $string2[] = $y->class->rule1;  
             }

I've written a possible solution for your query, which is quite similar to your previous question. Comments are mentioned wherever necessary. See if it helps you.

$nameArray = $this->session->userdata('namearray'); // access the session data like this (remove namearray with your session name)

foreach ($nameArray as $x){ // traverse the data

    foreach($x->class as $class){ // now traverse the class array which is an object of parent array

        $newArr[][] = $class->rule1;  // use -> to access objects

    }
}

This will return an array like

// print_r($newArr);

[0] => 
      [0] => a
      [1] => b
[1] => 
      [0] => c
      [1] => d

What do you mean by two array? Like first array will have a and b, and second will have c and d Like so? @Loka

Can you share the desired output in the question?

inside the second foreach $string2[]=$class->rule1; and then $data = array( 'rule' =>$string2 ); $this->load->view('view',$data)
