Memcached::prepend

(PECL memcached >= 0.1.0)

Memcached::prependPrepend data to an existing item

설명

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

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.

Note: 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.

인수

key

The key of the item to prepend the data to.

value

The string to prepend.

반환값

성공할 경우 TRUE를, 실패할 경우 FALSE를 반환합니다. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.
