Memcached::getDelayed

(PECL memcached >= 0.1.0)

Memcached::getDelayedRequest multiple items

Descripción

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.

Parámetros

keys

Array of keys to request.

with_cas

Whether to request CAS token values also.

value_cb

The result callback or NULL.

Valores devueltos

Devuelve TRUE en caso de éxito o FALSE en caso de error. Use Memcached::getResultCode() si es necesario.

Ejemplos

Example #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(1112));

$m->getDelayed(array('int''array'), true);
var_dump($m->fetchAll());
?>

El resultado del ejemplo sería:

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)
  }
}
