Memcached::set
(PECL memcached >= 0.1.0)
Memcached::set — Store an item
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 -
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) {
}
