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.
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.
The key under which to store the value.
The value to store.
The expiration time, defaults to 0. See Expiration Times for more info.
Returns TRUE
on success or FALSE
on failure. Use Memcached::getResultCode() if necessary.
<?php $m = new Memcached(); $m->addServer('localhost', 11211); /* keep IP blocks on a certain server */ $m->setByKey('api-cache', 'block-ip:169.254.253.252', 1); $m->setByKey('api-cache', 'block-ip:169.127.127.202', 1); ?>
