Memcached::getMulti

(PECL memcached >= 0.1.0)

Memcached::getMulti — Retrieve multiple items

Описание

public mixed Memcached::getMulti ( array $keys [, array &$cas_tokens ] )

Memcached::getMulti() is similar to Memcached::get, but instead of a single key item, it retrievess multiple items the keys of which are specified in the keys array. If cas_tokens variable is provided, it is filled with the CAS token values for the found items.

Замечание: Unlike Memcached::get it is not possible to specify a read-through cache callback for Memcached::getMulti(), because the memcache protocol does not provide information on which keys were not found in the multi-key request.

Список параметров

keys: Array of keys to retrieve.
cas_tokens: The variable to store the CAS tokens for the found items.

Возвращаемые значения

Returns the array of found items or FALSE on failure. Use Memcached::getResultCode if necessary.

Примеры

Пример #1 Memcached::getMulti() example


<?php
$m = new Memcached();
$m->addServer('localhost', 11211);

$items = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
);
$m->setMulti($items);
$result = $m->getMulti(array('key1', 'key3', 'badkey'), $cas);
var_dump($result, $cas);
?>

Результатом выполнения данного примера будет что-то подобное:

array(2) {
  ["key1"]=>
  string(6) "value1"
  ["key3"]=>
  string(6) "value3"
}
array(2) {
  ["key1"]=>
  float(2360)
  ["key3"]=>
  float(2362)
}
