Memcached::getByKey — Retrieve an item from a specific server
Description
public mixed Memcached::getByKey
( string $server_key
, string $key
[, callback $cache_cb
[, float &$cas_token

Memcached::getByKey() is functionally equivalent to Memcached::get, except that the free-form server_key can be used to map the key to a specific server.
Parameters

The key identifying the server to store the value on.
- key
-
The key of the item to fetch.
- cache_cb
-
Read-through caching callback or NULL
- cas_token

The variable to store the CAS token in.
Return Values
Returns the value stored in the cache or FALSE otherwise. The Memcached::getResultCode will return Memcached::RES_NOTFOUND if the key does not exist.
