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:

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);

?>
