php > require __DIR__ . '/vendor/autoload.php';
php > $redis = new Predis\Client(['host' => '#####.publb.rackspaceclouddb.com', 'port' => 6379, 'password' => '#####']);

C.R.U.D.¶

Create, read, update and destroy are the four basic functions of persistent storage.

php > echo $redis->set("best_car_ever", "Tesla Model S");
OK

php > echo $redis->get("best_car_ever");
