Memcached::getMulti — Retrieve multiple items
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.
Note: 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.
Array of keys to retrieve.
The variable to store the CAS tokens for the found items.
Returns the array of found items or FALSE on failure. Use Memcached::getResultCode if necessary.
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);
?>
上例的输出类似于：
array(2) {
["key1"]=>
string(6) "value1"
["key3"]=>
string(6) "value3"
}
array(2) {
["key1"]=>
float(2360)
["key3"]=>
float(2362)
}
