With MAMP (using PHP 5.3.5 and APC 3.1.7) passing an array with multiple regex strings as $search arg always yields an empty APCIterator. Whereas passing a single string regex works. (Note: I only tried cache type 'user'.)

Workaround: Concatenated all regexes to single one with alternation. Example:

<?php
$results
= new APCIterator('user', '/^('.implode('|', $patterns).')');
?>

Iterating (and specifically using current()) does not expunge cache entries for which $ttl has passed, you need to use apc_fetch to get rid of stale entries.
