说明

Memcached::deleteMulti() deletes the array of keys from the server. The time parameter is the amount of time in seconds (or Unix time until which) the client wishes the server to refuse add and replace commands for these keys. For this amount of time, the item is put into a delete queue, which means that it won't be possible to retrieve it by the get command, but add and replace command with these keys will also fail (the set command will succeed, however). After the time passes, the item is finally deleted from server memory. The parameter time defaults to 0 (which means that the item will be deleted immediately and further storage commands with these keys will succeed).
