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
класата MongoDB\Driver\BulkWrite
MongoDB\BSON\Serializable::bsonSerialize — Provides an array or document to serialize as BSON
= NULL
Called during serialization of the object to BSON. The method must return an array, stdClass, MongoDB\BSON\Document, или MongoDB\BSON\PackedArray.
Root documents (e.g. a
MongoDB\BSON\Serializable passed to
објектите се создаваат преку статични методи на фабриката и не можат директно да се инстанцираат.) 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.
Users are encouraged to include an _id property (e.g. a MongoDB\BSON\ObjectId initialized in the constructor) when returning data for a BSON root document. In the absence of an _id property, the extension or server will generate a MongoDB\BSON\ObjectId for insert or upsert operations, respectively.

The return type was changed from array|object. Instead of object, the return type now specifies stdClass. Classes that implement this interface must be changed to no longer declare an object return type. As the return type is tentative, a deprecation warning is emitted on PHP 8.1 and newer. In addition to the changes above, the extension now also supports returning instances of MongoDB\BSON\Document and MongoDB\BSON\PackedArray. Please note that any MongoDB\BSON\PackedArray instances returned are silently converted to objects when stored as root documents. They are stored as arrays when used as an embedded field value. |
Примери
Пример #1 MongoDB\BSON\Serializable::bsonSerialize() returning an associative array for root document
<?php
class MyDocument implements MongoDB\BSON\Serializable
{
private $id;
function __construct()
{
$this->id = new MongoDB\BSON\ObjectId;
}
function bsonSerialize(): array
{
return ['_id' => $this->id, 'foo' => 'bar'];
}
}
echo MongoDB\BSON\Document::fromPHP(new MyDocument)->toRelaxedExtendedJSON(), "\n";
?>Горниот пример ќе прикаже нешто слично на:
{ "_id" : { "$oid" : "56cccdcada14d8755a58c591" }, "foo" : "bar" }
Пример #2 MongoDB\BSON\Serializable::bsonSerialize() returning a sequential array for root document
<?php
class MyArray implements MongoDB\BSON\Serializable
{
function bsonSerialize(): array
{
return [1, 2, 3];
}
}
echo MongoDB\BSON\Document::fromPHP(new MyArray)->toRelaxedExtendedJSON(), "\n";
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
{ "0" : 1, "1" : 2, "2" : 3 }
Пример #3 MongoDB\BSON\Serializable::bsonSerialize() returning an associative array for document field
<?php
class MyDocument implements MongoDB\BSON\Serializable
{
function bsonSerialize(): array
{
return ['foo' => 'bar'];
}
}
$value = ['document' => new MyDocument];
echo MongoDB\BSON\Document::fromPHP($value)->toRelaxedExtendedJSON(), "\n";
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
{ "document" : { "foo" : "bar" } }
Пример #4 MongoDB\BSON\Serializable::bsonSerialize() returning a sequential array for document field
<?php
class MyArray implements MongoDB\BSON\Serializable
{
function bsonSerialize(): array
{
return [1, 2, 3];
}
}
$value = ['array' => new MyArray];
echo MongoDB\BSON\Document::fromPHP($value)->toRelaxedExtendedJSON(), "\n";
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
{ "array" : [ 1, 2, 3 ] }
