Memcached::prepend() prepends the given
value
string to the value of an existing item. The
reason that value
is forced to be a string is
that prepending 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 prepending
compressed data to a value that is potentially already compressed is not
possible.
Список параметров

value
The string to prepend.

The Memcached::getResultCode will return
Memcached::RES_NOTSTORED if the key does not exist.
