Memcached::deleteMulti()
(PECL memcached >= 2.0.0)
Delete multiple items
说明
public Memcached::deleteMulti(array $keys[,int $time= 0]): array
Memcached::deleteMulti() deletes the array of$keysfrom the server. The$timeparameter is the amount of time in seconds(or Unix time until which)the client wishes the server to refuseaddandreplacecommands for these keys. For this amount of time, the item is put into a delete queue, which means that it won't be possible to retrieve it by thegetcommand, butaddandreplacecommand with these keys will also fail(thesetcommand will succeed, however). After the time passes, the item is finally deleted from server memory. The parameter$timedefaults to 0(which means that the item will be deleted immediately and further storage commands with these keys will succeed).
参数
- $keys

- $time
The amount of time the server will wait to delete the items.
返回值
Returns array indexed by$keysand where values are indicating whether operation succeeded or not. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.
