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

說明

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_key can be used to map the keys to a specific server.

參數(shù)

server_key

本鍵名用于識別儲存和讀取值的服務(wù)器。沒有將實際的鍵名散列到具體的項目，而是在決定與哪一個 memcached 服務(wù)器通信時將其散列為服務(wù)器鍵名。這使得關(guān)聯(lián)的項目在單一的服務(wù)上被組合起來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

成功時返回 true， 或者在失敗時返回 false。 The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.
