MongoDB\BSON\MinKey::jsonSerialize

(mongodb >=1.2.0)

MongoDB\BSON\MinKey::jsonSerialize — Returns a representation that can be converted to JSON

Description

final public function MongoDB\BSON\MinKey::jsonSerialize(): mixed

Parameters

This function has no parameters.

Return Values

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

Note:
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.

Errors/Exceptions

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
