Unexpected T_VARIABLE is a parse error,
meaning that code syntax or structure is not valid.
This error usually occurs because of missing semicolon or bracket
somewhere before it's triggered.

class Upload extends CI_Controller
     {
        function __construct()
        {
           parent::__construct();
           $this->load->database();
           $this->load->library(array('session','ion_auth'));
           $this->load->helper(array('form', 'url'));    //error line HERE
           $this->load->model('User_profile_model', 'User_profile', TRUE);
        }
    }
