Memcached::prependPrepend data to an existing item


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

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.


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.



The key of the item to prepend the data to.


The string to prepend.

Valor Retornado

Retorna true em caso de sucesso ou false em caso de falha. The Memcached::getResultCode() will return Memcached::RES_NOTSTORED if the key does not exist.


Exemplo #1 Memcached::prepend() example
