How do I get the Array value using Codeigniter

Question

I have this select

    $this->db->select('modulo_regra.regra_descricao');
    $this->db->from('modulo_regra');
    $this->db->where('modulo_regra.modulo_regra_id', id);
    $query = $this->db->get();

that return to me 2 elements in

  return $query->result_array();

Then I put the return in a Array

   $permissoes =array('areas' => $this->Regra_model->user_has($regra['regra_id']));

then I the $permissoes to the session

   $this->session->set_userdata($permissoes);

So the real problem comes here. when I'm loading the value from session

   $permissoes = array('areas');
   $permissoes = $this->session->userdata('areas'); 

this is its content:

array(2) ([0] => array(1) ([regra_descricao] => (string) clientes_cadastrar)
          [1] => array(1) ([regra_descricao] => (string) clientes_visualizar))

So i can't validate it with the in_array(), or other way...I would like to know if there is how if there is away to compare the value in this array with one another variable

like

if(in_array('clientes_cadastrar',$permissoes)){}

I'm new on it... so sorry for the way i ask.

Solution 1

don't put entire array in return i.e

foreach ($query->result() as $row)
{
   $return[] = $row->regra_descricao;
}
return $return;

THEN

you can easily find using:

if(in_array('clientes_cadastrar',$permissoes[**'areas'**])){}

hope this helps

Solution 2

U can use the same scope.

 $this->db->select('modulo_regra.regra_descricao');
     $this->db->from('modulo_regra');
     $this->db->where('modulo_regra.modulo_regra_id', id);
     $query = $this->db->get();

    foreach ($query->result() as $row)
    {
       $permissoes = array['areas'];
    }

    $this->session->set_userdata($permissoes);
