    Memcached::append — Append data to an existing item

    Açıklama

    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.

    Bilginize:

    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.

    This method emits this php warning if OPT_COMPRESSION is not explicitly set to false (tested with libmemcached 1.0.18 & pecl-memcached 2.1.0):
