(PECL memcached >= 0.1.0)
Memcached::getDelayedByKey — Request multiple items from a specific server
Description
$server_key
, array $keys
[, bool $with_cas
[, callable $value_cb
]] )
Memcached::getDelayedByKey() is functionally equivalent to
Memcached::getDelayed(), except that the free-form
server_key can be used to map the
keys to a specific server.
Parameters
-
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.
-
keys -
Array of keys to request.
-
with_cas -
Whether to request CAS token values also.
-
value_cb -
The result callback or
NULL.
Return Values
Returns TRUE on success or FALSE on failure.
Use Memcached::getResultCode() if necessary.
