$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$collection = $schema->createCollection("people");
$result = $collection->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();

$ids = $result->getGeneratedIds();
$alfred_id = $ids[0];
// ...
