public function __construct() {
    parent::__construct();



}

public function index(){
$this->load->view('index.php');

}
public function blog(){
$this->load->view('arsiv');

}
public function test($param){
    $this->load->view('test');
    $a =  $this->uri->segment(2);


}
}

the uri class is loaded automatically, so i'm not sure how you are getting this error given that you've extended ci_controller. this is the exact code you are using? — Alex

Please verify the URL helper is enabled in your config function

try to use $this->uri->get_segment(1);

Try to use

$CI =& get_instance(); 
$this->CI->uri->segment('2')

Try to use

codigniter autoload.php file in config folder

$autoload['helper'] = array('url');

Url : http://localhost/laravel/users/abc
$product_id = $this->uri->segment(2);
Result : abc
