Message: syntax error, unexpected T_DOUBLE_ARROW

Question

I am getting below error

A PHP Error was encountered Severity: Parsing Error

Message: syntax error, unexpected T_DOUBLE_ARROW

Filename: controllers/Welcome.php

Line Number: 15

Backtrace:

my code is

<?php
    defined('BASEPATH') OR exit('No direct script access allowed');    
    class Welcome extends CI_Controller {
        public function __construct(){ 
            parent::__construct();
            $this->load->model('HotelModel');
        }    
        public function index(){    
            $hotData = $this->HotelModel->getAllHotelList();
            $cityData = $this->HotelModel->getAllHotelCity(); 
            $this->load->view('public/index',('hotData' => $hotData,'cityData' => $cityData));
        }
    }
?>

I am not able to find my mistake.
