Memcached::deleteMulti
(PECL memcached >= 2.0.0)
Memcached::deleteMulti — Delete multiple items
说明
public Memcached::deleteMulti
( array $keys
[, int $time
= 0
] ) : array
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).
参数
keys
- The keys to be deleted.
time
- The amount of time the server will wait to delete the items.
返回值
Returns array indexed by keys
and where values are indicating whether operation succeeded or not.
The Memcached::getResultCode() will return
Memcached::RES_NOTFOUND
if the key does not exist.
