Parse error: syntax error, unexpected $end caused by foreach in view

Now I am getting each string from the controller and my first and last name our showing, but I am getting an error: Trying to get property of non-object. I am getting this error for every string I echo in my view which is currently the $first_name and $last_name,

Code:

function members_area()
{
  $this->load->model('Membership_model');
  $data = $this->Membership_model->retrieve();
  $first_name = $data['first_name'];
  $first_name = $data->first_name;
  $last_name = $data['last_name'];
  $last_name = $data->last_name;
  //$data['t'] = $this->db->get('membership','first_name');    //Need to have result before converting to a string.
  $this->load->view('logged_in_area', $data);

Code:

function retrieve()
   {
    $this->db->where('email_address', $this->input->post('email_address'));  //validate username
    $q = $this->db->get('membership');

    if($q->num_rows() > 0) {
      // return a single db row array $row['name'];
      return $q->row_array();
      // return a single db object $row->name;
      // return $q->row;      
     }
     return FALSE;

  
    
  }

}
