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) {
