Memcached::set

(PECL memcached >= 0.1.0)

Memcached::setStore an item

Descrizione

public bool Memcached::set ( string $key , mixed $value [, int $expiration ] )

Memcached::set() stores the value on a memcache server under the specified key. The expiration parameter can be used to control when the value is considered expired.

The value can be any valid PHP type except for resources, because those cannot be represented in a serialized form. If the Memcached::OPT_COMPRESSION option is turned on, the serialized value will also be compressed before storage.

Elenco dei parametri

key

La chiave in cui salvare il valore.

value

Il valore da salvare.

expiration

La data di scadenza, il default è 0. Vedere Date di scadenza per ulteriori informazioni.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento. Utilizzare Memcached:getResultCode() se necessario.

Esempi

Example #1 Memcached::set() example

<?php
$m 
= new Memcached();
$m->addServer('localhost'11211);

$m->set('int'99);
$m->set('string''a simple string');
$m->set('array', array(1112));
/* expire 'object' key in 5 minutes */
$m->set('object', new stdclasstime() + 300);


var_dump($m->get('int'));
var_dump($m->get('string'));
var_dump($m->get('array'));
var_dump($m->get('object'));
?>

Il precedente esempio visualizzerà qualcosa simile a:

int(99)
string(15) "a simple string"
array(2) {
  [0]=>
  int(11)
  [1]=>
  int(12)
}
object(stdClass)#1 (0) {
}

The method correctly returns false if you set the value to false. This means that in order to have proper fault checking mechanism in place you need to check the result code.

<?php
$Memcached
= new Memcached();
$Memcached->addServer('localhost', 11211);
$Memcached->set('key', false);
var_dump($Memcached->get('key'));      // boolean false
var_dump($Memcached->getResultCode()); // int 0 which is  Memcached::RES_SUCCESS 
?>
