Question

my framework is codeigniter.

I want to use redis. I'm using predis.

https://packagist.org/packages/predis/predis

but I got this error:

An uncaught Exception was encountered

Type: Predis\Connection\ConnectionException

Message: No connection could be made because the target machine actively refused it. [tcp://127.0.0.1:6379]

my codes:

\Predis\Autoloader::register();
$redis = new \Predis\Client(array(
    "scheme" => "tcp",
    "host" => "127.0.0.1",
    "port" => 6379));

$client = new \Predis\Client();

$client->set('foo', 'bar');
$value = $client->get('foo');

echo $value;
return ;

1. Installing Redis

Firstly you need to understand, that you've to install Redis as a serparate Service. You can't simply install a Redis Client like PRedis without a Redis Server.

Since it was supported by the MSOpentechGroup there are several Windows Forks on Github out there, but unfortunately nobody maintains this forks anymore. You can see a conversation about this topic here.

Anway, you find the download of the latest build here.

2. Installing the client

You can choose PRedis as a standalone PHP Library which is much slower compared to PHPRedis.

The official Codeigniter documentation recommends PHPRedis because its caching driver depends on it. You can find more information here.

Installing PHPRedis on Windows depends on your PHP Version. If you tell me your PHP Version i'm certainly willing to help you to find the correct driver.

3. Using it with Codeigniter

Since CI has an out of the box Driver for that you simple have to study this page here.
