Memcached::getDelayedByKey — Request multiple items from a specific server

Description

public Memcached::getDelayedByKey ( string $server_key , array $keys [, bool $with_cas [, callable $value_cb ]] ) : bool

Memcached::getDelayedByKey() is functionally equivalent to Memcached::getDelayed(), except that the free-form server_key can be used to map the keys to a specific server.

Parameters

server_key

The key identifying the server to store the value on or retrieve it from. Instead of hashing on the actual key for the item, we hash on the server key when deciding which memcached server to talk to. This allows related items to be grouped together on a single server for efficiency with multi operations.

keys

Array of keys to request.

with_cas

Whether to request CAS token values also.

value_cb

The result callback or NULL.
