Docs > Redis Commands > P > Pexpire
This command works exactly like EXPIRE
but the time to live of the key is
specified in milliseconds instead of seconds.
Options
The PEXPIRE
command supports a set of options since Redis 7.0:
NX
-- Set expiry only when the key has no expiryXX
-- Set expiry only when the key has an existing expiryGT
-- Set expiry only when the new expiry is greater than current oneLT
-- Set expiry only when the new expiry is less than current one
A non-volatile key is treated as an infinite TTL for the purpose of GT
and LT
.
The GT
, LT
and NX
options are mutually exclusive.
@return
@integer-reply, specifically:
1
if the timeout was set.0
if the timeout was not set. e.g. key doesn't exist, or operation skipped due to the provided arguments.
@examples
SET mykey "Hello"
PEXPIRE mykey 1500
TTL mykey
PTTL mykey
PEXPIRE mykey 1000 XX
TTL mykey
PEXPIRE mykey 1000 NX
TTL mykey
