示例1: append
/**
* Append data to an existing item.
*
* This method should throw an error if it is used with compressed data. This
* is an expected behavior. Memcached casts the value to be appended to the initial value to the
* type of the initial value. Be careful as this leads to unexpected behavior at times. Due to
* how memcached treats types, the behavior has been mimicked in the internal cache to produce
* similar results and improve consistency. It is recommend that appends only occur with data of
* the same type.
*
* @link http://www.php.net/manual/en/memcached.append.php
*
* @param string $key The key under which to store the value.
* @param mixed $value Must be string as appending mixed values is not well-defined.
* @param string $group The group value appended to the $key.
* @param string $server_key The key identifying the server to store the value on.
* @param bool $byKey True to store in internal cache by key; false to not store by key
* @return bool Returns TRUE on success or FALSE on failure.
