Redis Stack server.
See Getting started for Redis installation
instructions.

library
with the following command line:

Connect and test
Connect to a locally-running server on the standard port (6379) with the following code:
<?php
require 'vendor/autoload.php';
use Predis\Client as PredisClient;
$r = new PredisClient();
Store and retrieve a simple string to test the connection:
echo $r->set('foo', 'bar'), PHP_EOL;
// >>> OK
echo $r->get('foo'), PHP_EOL;
// >>> bar
Store and retrieve a hash object:
$r->hset('user-session:123', 'name', 'John');
$r->hset('user-session:123', 'surname', 'Smith');
$r->hset('user-session:123', 'company', 'Redis');
$r->hset('user-session:123', 'age', 29);
echo var_export($r->hgetall('user-session:123')), PHP_EOL;
/* >>>
array (
'name' => 'John',
'surname' => 'Smith',
'company' => 'Redis',
'age' => '29',
)
*/
