SMISMEMBER checks each member against the set stored at key and returns one result per member, in the order given. A missing key behaves like an empty set.

Return value

Section titled “Return value”
Case RESP2 RESP3
Success Array of integers: 1 for a member, 0 otherwise Same

SMISMEMBER replies with a WRONGTYPE error if key holds a value that is not a set.
