Memcached – Can't caching object in codeigniter

I have this following code in the Address controller

public function index()
    {
        if($this->session->userdata('isLogin')) {
            $this->load->driver('cache');
            $this->load->model('MemberModel');
            if(!$this->cache->get('province') == false) {
                $this->load->model('ShippingModel');
                $data['provinces'] = $this->ShippingModel->the_provinces(); // it will return json object
                $this->cache->save('province', $data['provinces'], 300);
            } else {
                $data['provinces'] = $this->cache->get('province');
            }
            $userdata = $this->MemberModel->getProfile($this->session->userdata('userid'));
            $data['user'] = $userdata;

            $this->display_member_area('member/address', $data);
        }
        else {
            redirect(base_url());
        }
    }

When I want to get the data using:

var_dump($this->cache->get('province'));

the result I get always shows

bool(false)

but when I tried to do this instead

var_dump($data['provinces']) // it's show me json object, that I want

Can anyone please show me where I’am doing wrong?

Thanks in advance

    Remove false from the if condition and use this code. 

           if(!$this->cache->get('province')) {
            $this->load->model('ShippingModel');
            $data['provinces'] = $this->ShippingModel->the_provinces();
            $this->cache->save('province', $data['provinces'], 300);
        } else {
            $data['provinces'] = $this->cache->get('province');
        }

    Make sure you have the correct credential on your config at:

    https://github.com/bcit-ci/CodeIgniter/blob/develop/application/config/memcached.php

    it will be at you application/config/memcached.php file. Hostname is the ip you setup your memcached instance. You could provide multiple server if you wish.
