Memcached::set

Description

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

Key

value

Value

expiration

Return Values

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) {
}
