PHP - Manual: Memcached::incrementByKey

2025-05-09

Memcached::incrementByKey

(PECL memcached >= 2.0.0)

Memcached::incrementByKeyIncrement numeric item's value, stored on a specific server

说明

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.

参数

server_key

本键名用于识别储存和读取值的服务器。没有将实际的键名散列到具体的项目,而是在决定与哪一个 memcached 服务器通信时将其散列为服务器键名。这使得关联的项目在单一的服务上被组合起来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 或者在失败时返回 false.
