Memcached::setByKey

(PECL memcached >= 0.1.0)

Memcached::setByKeyStore an item on a specific server

说明

public bool Memcached::set ( string $server_key , string $key , mixed $value [, int $expiration ] )

Memcached::setByKey() is functionally equivalent to Memcached::set, except that the free-form server_key can be used to map the key to a specific server. This is useful if you need to keep a bunch of related keys on a certain server.

参数

server_key

The key identifying the server to store the value on.

key

The key under which to store the value.

value

The value to store.

expiration

The expiration time, defaults to 0. See Expiration Times for more info.

返回值

如果成功则返回 TRUE,失败则返回 FALSE。 Use Memcached::getResultCode if necessary.

范例

Example #1 Memcached::setByKey() example

$m->setByKey('api-cache''block-ip:169.127.127.202'1);
