    <?php
    $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":   "Bernie",
        "traits": ["Friend", "Brother", "Human"]}')
      ->execute();

    $collection
      ->modify("name in ('Bernie', 'Jane')")
      ->arrayAppend('traits', 'Happy')
      ->execute();

    $result = $collection
      ->find()
      ->execute();

    print_r($result->fetchAll());
    ?>

    Array
    (
        [0] => Array
            (
                [_id] => 00005b6b5361000000000000010c
                [name] => Bernie
                [traits] => Array
                    (
                        [0] => Friend
                        [1] => Brother
                        [2] => Human
                        [3] => Happy
                    )
            )
    )
