Memcached::set — Store an item
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.
The key under which to store the value.
The value to store.
The expiration time, defaults to 0. See Expiration Times for more info.
如果成功则返回 TRUE，失败则返回 FALSE。 Use Memcached::getResultCode if necessary.
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'));
?>
上例的输出类似于：
int(99)
string(15) "a simple string"
array(2) {
[0]=>
int(11)
[1]=>
int(12)
}
object(stdClass)#1 (0) {
}
