Memcached::getDelayed — Request multiple items
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.
Array of keys to request.
Whether to request CAS token values also.
The result callback or NULL.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben. Benutzen Sie wenn nötig Memcached::getResultCode().
Beispiel #1 Memcached::getDelayed() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
$m->set('int', 99);
$m->set('string', 'a simple string');
$m->set('array', array(11, 12));
$m->getDelayed(array('int', 'array'), true);
var_dump($m->fetchAll());
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
array(2) { [0]=> array(3) { ["key"]=> string(3) "int" ["value"]=> int(99) ["cas"]=> float(2363) } [1]=> array(3) { ["key"]=> string(5) "array" ["value"]=> array(2) { [0]=> int(11) [1]=> int(12) } ["cas"]=> float(2365) } }
