(mongodb >=1.4.0)

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

说明

final public MongoDB\BSON\Symbol::jsonSerialize ( void ) : mixed

参数

此函数没有参数。

返回值

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

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.

错误／异常

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