Example #1 mysql_xdevapi\Collection::getOne() example

    <?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": "Alfred", "age": 42, "job": "Butler"}')->execute();// A unique _id is (by default, and recommended) generated by MySQL Server// This retrieves the generated _id's; only one in this example, so $ids[0]$ids        = $result->getGeneratedIds();$alfreds_id = $ids[0];// ...print_r($alfreds_id);print_r($collection->getOne($alfreds_id));?>

        [job] => Butler
        [name] => Alfred
