MongoBinData::__construct — Creates a new binary data object.
$data
   [, int $type = 0
  ] )Creates a new binary data object.
   There are seven types of binary data currently recognized by the BSON spec,
   which are defined as
   class constants. For
   backwards compatibility, the PHP driver uses
   MongoBinData::BYTE_ARRAY as the default; however, this
   may change to MongoBinData::GENERIC in the future.
   Users are encouraged to specify a type instead of relying on the default.
