Memcached::setOption — Set a Memcached option
This method sets the value of a Memcached option. Some options correspond to the ones defined by libmemcached, and some are specific to the extension. See Memcached Constants for more information.
The options listed below require values specified via constants.
Memcached::OPT_HASH requires Memcached::HASH_* values.
Memcached::OPT_DISTRIBUTION requires Memcached::DISTRIBUTION_* values.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 Setting a Memcached option
<?php
$m = new Memcached();
var_dump($m->getOption(Memcached::OPT_HASH) == Memcached::HASH_DEFAULT);
$m->setOption(Memcached::OPT_HASH, Memcached::HASH_MURMUR);
$m->setOption(Memcached::OPT_PREFIX_KEY, "widgets");
echo "Prefix key is now: ", $m->getOption(Memcached::OPT_PREFIX_KEY), "\n";
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
bool(true) Prefix key is now: widgets
Be warned that setting the option Memcached::OPT_DISTRIBUTION to Memcached::DISTRIBUTION_CONSISTENT can carry a significant performance hit so is best used with persistent connections. More details at http://github.com/andreiz/php-memcached/issues#issue/14
