Memcached::appendByKey

Append data to an existing item on a specific server

Description

public bool Memcached::appendByKey ( string $server_key , string $key , string $value )

Memcached::appendByKey is functionally equivalent to Memcached::append, 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 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.

key

The key under which to store the value.

value

The string to append.

Return Values

Returns TRUE on success or FALSE on failure. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.
