Memcached::replaceByKey
The method correctly returns false if you set the value to false. This means that in order to have proper fault checking mechanism in place you need to check the result code.
<?php
$Memcached = new Memcached();
$Memcached->addServer('localhost', 11211);
$Memcached->set('key', false);
var_dump($Memcached->get('key')); // boolean false
var_dump($Memcached->getResultCode()); // int 0 which is Memcached::RES_SUCCESS
?>
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) {
}
