HPTTL works like HTTL, but reports the remaining time to live of each listed field in milliseconds.

Return value

Section titled “Return value”

An array with one integer per field, in the order given, under both RESP2 and RESP3:

Value Meaning
-2 The field or the key does not exist.
-1 The field exists but has no time to live.
0 or more The remaining time to live in milliseconds.

The errors are the same as for HTTL.
