memcached entry expiration set to 0

Question

Does memcached entries with expiry time set to 0 not expire - as mentioned in the PHP Memcached docs, but not mentioned in the memcached protocol spec?

I am using spymemcached client and the docs for spymemcached does not say anything about it either.

Answer 1

Setting expiration to 0 means the item has no expiration. Therefore it will never expire.
