Hi,
I want to display a error screen with `show_error` when redis server does not start.
But RedisException occured on `__destruct`.
What should I do?
## error log
Code:

## my codes
PHP Code:
class Welcome extends CI_Controller {
public function index()
{
$this->load->driver('cache', ['adapter' => 'redis']);
if ($this->cache->is_supported('redis'))
{
echo 'redis connection was established';
}
else
{
show_error('redis connection was not established', 500);
}
// $this->load->view('welcome_message');
}
}

<?php

$config['socket_type'] = 'tcp'; //`tcp` or `unix`
$config['host'] = '127.0.0.1';
$config['password'] = NULL;
$config['port'] = 6379;
$config['timeout'] = 0;
