Exemplo #1 mysql_xdevapi\Collection::replaceOne() example

<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");

$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();

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

// ...

$alfred = $collection->getOne($alfred_id);
$alfred['age'] = 81;
$alfred['job'] = 'Guru';
