MongoDB\BSON\Int64::jsonSerialize — Returns a representation that can be converted to JSON
此函數沒(méi)有參數。
Returns data which can be serialized by json_encode() to produce an extended JSON representation of the MongoDB\BSON\Int64.
注意: The output is consistent with the MongoDB\BSON\toCanonicalExtendedJSON() function, which uses the ? canonical extended JSON format. This differs from other BSON classes, which use the driver-specific legacy extended JSON format (MongoDB\BSON\toJSON()), in order to ensure that the 64-bit integer value is correctly represented on 32-bit platforms.
