Memcached::append — Append data to an existing item

Description

public Memcached::append ( string $key , string $value ) : bool

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.

Note:

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.
