### Examples

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));
    ?>

The above example will output something similar to:

    00005b6b536100000000000000b1

    Array
    (
        [_id] => 00005b6b536100000000000000b1
        [age] => 42
        [job] => Butler
        [name] => Alfred
    )
