Memcached::deleteByKey

(PECL memcached >= 0.1.0)

Memcached::deleteByKeyDelete an item from a specific server

Description

public bool Memcached::deleteByKey ( string $server_key , string $key [, int $time = 0 ] )

Memcached::deleteByKey() is functionally equivalent to Memcached::delete(), except that the free-form server_key can be used to map the key to a specific server.

Parameters

server_key

The key identifying the server to store the value on or retrieve it from. Instead of hashing on the actual key for the item, we hash on the server key when deciding which memcached server to talk to. This allows related items to be grouped together on a single server for efficiency with multi operations.

key

The key to be deleted.

time

The amount of time the server will wait to delete the item.

Return Values

Returns TRUE on success or FALSE on failure. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.
