Memcached::append — Append data to an existing item
Memcached::append() appends the given value string to the value of an existing item. The reason that value is forced to be a string is that appending mixed types is not well-defined.
Замечание:
If the Memcached::OPT_COMPRESSION is enabled, the operation will fail and a warning will be issued, because appending compressed data to a value that is potentially already compressed is not possible.

$m->append('foo', 'def');
var_dump($m->get('foo'));
