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.
Зауваження:
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.

value
The string to append.
Повертає true
у разі успіху або false
