(PECL memcached >= 0.1.0)

Memcached::set — Store an item

### Description

public Memcached::set(string `$key`, mixed `$value`, int `$expiration` = 0): bool

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) {
    }
