Memcached::deleteMultiByKey

(PECL memcached >= 2.0.0)

Memcached::deleteMultiByKey — Delete multiple items from a specific server

说明

public Memcached::deleteMultiByKey(string $server_key, array $keys, int $time = 0): array

Memcached::deleteMultiByKey() is functionally equivalent to Memcached::deleteMulti(), except that the free-form server_key can be used to map the keys to 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.

注意: As of memcached 1.3.0 (released 2009) this feature is no longer supported. Passing a non-zero time will cause the deletion to fail. Memcached::getResultCode() will return MEMCACHED_INVALID_ARGUMENTS.

返回值

Returns an array indexed by keys. Each element is true if the corresponding key was deleted, or one of the Memcached::RES_* constants if the corresponding deletion failed.

The Memcached::getResultCode() will return the result code for the last executed delete operation, that is, the delete operation for the last element of keys.
