Predefined Constants


Generic binary data.




Generic binary data (deprecated in favor of MongoDB\BSON\Binary::TYPE_GENERIC).


Universally unique identifier (deprecated in favor of MongoDB\BSON\Binary::TYPE_UUID). When using this type, the Binary's data should be 16 bytes in length.

Historically, other drivers encoded values with this type based on their language conventions (e.g. varying endianness), which makes it non-portable. The PHP driver applies no special handling for encoding or decoding data with this type.


Universally unique identifier. When using this type, the Binary's data should be 16 bytes in length and encoded according to » RFC 4122.


MD5 hash. When using this type, the Binary's data should be 16 bytes in length.


User-defined type. While types between 0 and 127 are predefined or reserved, types between 128 and 255 are user-defined and may be used for anything.


Version Description
1.2.0 Implements Serializable and JsonSerializable.
