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

說明

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

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.

參數(shù)

server_key

本鍵名用于識別儲存和讀取值的服務器。沒有將實際的鍵名散列到具體的項目，而是在決定與哪一個 memcached 服務器通信時將其散列為服務器鍵名。這使得關(guān)聯(lián)的項目在單一的服務上被組合起來以提高多重操作的效率。

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.

返回值

Returns new item's value on success 或者在失敗時返回 false.
