Memcached::incrementByKey — Increment numeric item's value, stored on a specific server

Açıklama

public Memcached::incrementByKey ( string $server_key , string $key [, int $offset = 1 [, int $initial_value = 0 [, int $expiry = 0 ]]] ) : int

Memcached::incrementByKey() increments a numeric item's value by the specified offset. If the item's value is not numeric, an error will result. Memcached::incrementByKey() will set the item to the initial_value parameter if the key doesn't exist.

Değiştirgeler

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 of the item to increment.
offset: The amount by which to increment the item's value.
initial_value: The value to set the item to if it doesn't currently exist.
expiry: The expiry time to set on the item.
