Memcached::append || Memcached::cas || Memcached || PHP Manual

(PECL memcached >= 0.1.0)

Memcached::appendByKeyAppend data to an existing item on a specific server


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.



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.


The key under which to store the 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.
