Memcached::set

Memcached::set

(PECL memcached >= 0.1.0)

Memcached::set — Store an item

Description

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.

Parameters

key

The key under which to store the value.

value

The value to store.

expiration

The expiration time, defaults to 0. See Expiration Times for more info.

Return Values

Returns TRUE on success or FALSE on failure. Use Memcached::getResultCode() if necessary.

Examples

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(11, 12) /* expire 'object' key in 5 minutes */ $m->set('object', new stdclass, time() + 300 var_dump($m->get('int') var_dump($m->get('string') var_dump($m->get('array') var_dump($m->get('object') ?>

The above example will output something similar to:

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