Object of class stdClass could not be converted to string

Question

I am having a problem with PHP at the moment, I am getting this error,

Object of class stdClass could not be converted to string the error occurs when I run this portion of code in my site,

function myaccount() {     $data['user_data'] = $this->auth->get_userdata($this->uri->segment(3));     //var_dump($data['user_data']);     $this->load->model('users_model');     $data['user_info'] = $this->users_model->get_user_and_roadmaps_by_id($this->uri->segment(3));     $this->template->build('users/my_account', $data); } 

The line in which the error is occuring is this one,

$data['user_data'] = $this->auth->get_userdata($this->uri->segment(3)); 

And this line is calling this function,

   function get_userdata() {          $CI =& get_instance();          if(!$this->logged_in()) {             return false;         } else {             $query = $CI->db->get_where('users', array('user_id' => $CI->session->userdata('user_id')));             return $query->row();         }     } 

I don't really now what this problem is, so any help would be great.

Most likely, the userdata() function is returning an object, not a string. Look into the documentation (or var_dump the return value) to find out which value you need to use.
