Memcached::getDelayed — Request multiple items

Описание

public bool Memcached::getDelayed ( array $keys [, bool $with_cas [, callback $value_cb ]] )

Memcached::getDelayed() issues a request to memcache for multiple items the keys of which are specified in the keys array. The method does not wait for response and returns right away. When you are ready to collect the items, call either Memcached::fetch or Memcached::fetchAll. If with_cas is true, the CAS token values will also be requested.

Instead of fetching the results explicitly, you can specify a result callback via value_cb parameter.

Список параметров

keys: Array of keys to request.
with_cas: Whether to request CAS token values also.
value_cb: The result callback or NULL.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки. Use Memcached::getResultCode if necessary.
