MongoDB\BSON\Undefined::jsonSerializeReturns a representation that can be converted to JSON

説明

final public MongoDB\BSON\Undefined::jsonSerialize(): mixed

パラメータ

この関数にはパラメータはありません。

戻り値

Returns data which can be serialized by json_encode() to produce an extended JSON representation of the MongoDB\BSON\Undefined.

注意: The output is consistent with the MongoDB\BSON\toJSON() function, which uses the driver-specific legacy extended JSON format. This does not necessarily match the » relaxed or » canonical extended JSON representations used by MongoDB\BSON\toRelaxedExtendedJSON() and MongoDB\BSON\toCanonicalExtendedJSON(), respectively.
