Example #1 MongoDB\BSON\Unserializable::bsonUnserialize() example

<?php

class MyDocument implements MongoDB\BSON\Unserializable
{
private $data = [];

function bsonUnserialize(array $data): void
{
$this->data = $data;
}
}

$bson = MongoDB\BSON\Document::fromJSON('{ "foo": "bar" }');

var_dump($bson->toPHP(['root' => 'MyDocument']));

?>

    string(3) "bar"
  }
}
