trying to show off using the new __serialize() and __unserialize() magic methods

Create.php

<?php
require 'vendor/autoload.php';

use App\Model\Users;
use Symfony\Component\Uid\Uuid;

$mongo = new MongoDB\Client('mongodb://localhost:27017/');

$collection = $mongo->selectCollection('demo', 'users');

$user = new Users();
$user->userUuid = Uuid::v4()->toRfc4122();
$user->emailAddress = 'ac1Xo2NmH@example.com';
$user->firstName = 'Mouse';
$user->lastName = 'Provide';
$user->roles = ['USER'];

$result = $collection->insertOne($user);

echo 'Inserted with Object ID: '. $result->getInsertedId()."\n";

GetOne.php

<?php
require 'vendor/autoload.php';

$typeMap = [
    'array' => 'array',
    'document' => 'MongoDB\Model\BSONDocument',
    'root' => 'MongoDB\Model\BSONDocument'
];

$mongo = new MongoDB\Client('mongodb://localhost:27017/');

$collection = $mongo->selectCollection('demo', 'users');

$query = [
    'UserUuid' => '47f4b337-cd9d-446a-b030-c311e534e94a'
];

$document = $collection->findOne($query, ['typeMap' => $typeMap]);

if (null === $document)
{
    echo "Nothing was found.\n";
}
else
{
    var_dump($document);
}
