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
)
