As of version 3.0.13 APC (released 2007-02-24) you can perform multiple key fetches with apc_fetch. Very useful to further optimize your application!
APC changelog:
http://pecl.php.net/package-changelog.php?package=APC

example:

<?php
apc_store('key1', 'value1');
apc_store('key2', 'value2');

$keys = array('key1','key2');
$result = apc_fetch($keys);  //fetch multiple keys at once!

var_dump($result);
?>
