This documentation seems to be obsolete because I tried the first example and it doesn't convert the objectId to a string.
This seems to be more current documentation but I can't figure out how to get bson to json

MongoDB\BSON\Serializable::bsonSerialize
(mongodb >=1.0.0)
MongoDB\BSON\Serializable::bsonSerialize — Provides an array or document to serialize as BSON
Опис
Called during serialization of the object to BSON. The method must return an array or stdClass.
Root documents (e.g. a MongoDB\BSON\Serializable passed to MongoDB\BSON\fromPHP()) will always be serialized as a BSON document. For field values, associative arrays and stdClass instances will be serialized as a BSON document and sequential arrays (i.e. sequential, numeric indexes starting at 0) will be serialized as a BSON array.

Приклади
Приклад #1 MongoDB\BSON\Serializable::bsonSerialize() returning an associative array for root document

echo MongoDB\BSON\toJSON($bson), "\n";
?>
Наведений вище приклад виведе:
{ "foo" : "bar" }
Приклад #2 MongoDB\BSON\Serializable::bsonSerialize() returning a sequential array for root document
<?php
class MyArray implements MongoDB\BSON\Serializable
{
function bsonSerialize()
{
return [1, 2, 3];
}
}
$bson = MongoDB\BSON\fromPHP(new MyArray);
echo MongoDB\BSON\toJSON($bson), "\n";
?>
Наведений вище приклад виведе:
{ "0" : 1, "1" : 2, "2" : 3 }
Приклад #3 MongoDB\BSON\Serializable::bsonSerialize() returning an associative array for document field
<?php
class MyDocument implements MongoDB\BSON\Serializable
