PHP 5.6.0 released

Memcached::getMulti

(PECL memcached >= 0.1.0)

Memcached::getMultiRetrieve multiple items

Descrizione

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

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.

Nota:

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.

Elenco dei parametri

keys

Array of keys to retrieve.

cas_tokens

The variable to store the CAS tokens for the found items.

flags

The flags for the get operation.

Valori restituiti

Returns the array of found items o FALSE in caso di fallimento. Utilizzare Memcached:getResultCode() se necessario.

Esempi

Example #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);
?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

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

Example #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',
);

$m->setMulti($data3600);

$null null;
$keys array_keys($data);
$keys[] = 'zoo';
$got $m->getMulti($keys$nullMemcached::GET_PRESERVE_ORDER);

foreach (
$got as $k => $v) {
    echo 
"$k $v\n";
}
?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

foo foo-data
bar bar-data
baz baz-data
lol lol-data
kek kek-data
zoo
