(PECL memcached >= 0.1.0)

Memcached::set — Store an item

설명

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.

인수

key: 값을 저장할 키.
value: 저장할 값.
expiration: 만료 시간, 기본값은 0. 자세한 정보는 만료 시간을 참고하십시오.

반환값

성공할 경우 TRUE를, 실패할 경우 FALSE를 반환합니다. 필요할 경우 Memcached::getResultCode() 사용.

예제

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'));
?>

위 예제의 출력 예시:

int(99)
string(15) "a simple string"
array(2) {
  [0]=>
  int(11)
  [1]=>
  int(12)
}
object(stdClass)#1 (0) {
}

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  

?>
