Memcached::deleteMultiByKey()
(PECL memcached >= 2.0.0)
Delete multiple items from a specific server
说明
public Memcached::deleteMultiByKey(string $server_key,array $keys[,int $time= 0]): bool
Memcached::deleteMultiByKey() is functionally equivalent to Memcached::deleteMulti(), except that the free-form$server_keycan be used to map the$keysto a specific server.
参数
- $server_key
本键名用于识别储存和读取值的服务器。没有将实际的键名散列到具体的项目，而是在决定与哪一个 memcached 服务器通信时将其散列为服务器键名。这使得关联的项目在单一的服务上被组合起来以提高多重操作的效率。
- $keys
The keys to be deleted.
- $time
The amount of time the server will wait to delete the items.
返回值
成功时返回TRUE，或者在失败时返回FALSE。 The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.
