Memcached::getMulti — Retrieve multiple items
Memcached::getMulti() is similar to Memcached::get(), but instead of a single key item, it retrieves 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.
The flags parameter can be used to specify additional options for Memcached::getMulti(). Currently, the only available option is Memcached::GET_PRESERVE_ORDER that ensures that the keys are returned in the same order as they were requested in.
Array of keys to retrieve.
The variable to store the CAS tokens for the found items.
The flags for the get operation.
Returns the array of found items или FALSE в случае возникновения ошибки. Используйте при необходимости Memcached::getResultCode().
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)
}
Пример #2 Memcached::GET_PRESERVE_ORDER example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
$data = array(
'foo' => 'foo-data',
'bar' => 'bar-data',
'baz' => 'baz-data',
'lol' => 'lol-data',
'kek' => 'kek-data',
);
$m->setMulti($data, 3600);
$null = null;
$keys = array_keys($data);
$keys[] = 'zoo';
$got = $m->getMulti($keys, $null, Memcached::GET_PRESERVE_ORDER);
foreach ($got as $k => $v) {
echo "$k $v\n";
}
?>
Результатом выполнения данного примера будет что-то подобное:
foo foo-data bar bar-data baz baz-data lol lol-data kek kek-data zoo
