Memcached::set

(PECL memcached >= 0.1.0)

Memcached::setStore an item

Descrierea

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.

Parametri

key

Cheia sub care se stochează valoarea.

value

Valoarea pentru a fi stocată.

expiration

Timpul expirării, implicit este 0. Accesați Timpurile de expirare pentru informații suplimentare.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului. Utilizați Memcached::getResultCode() dacă e necesar.

Exemple

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'));
?>

Exemplul de mai sus va afișa ceva similar cu:

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 
?>
