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

`server_key`

  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.
