/**
* The APCUIterator class
*
* The APCUIterator class makes it easier to iterate over large APCu caches.
* This is helpful as it allows iterating over large caches in steps, while grabbing a defined number
* of entries per lock instance, so it frees the cache locks for other activities rather than hold up
* the entire cache to grab 100 (the default) entries. Also, using regular expression matching is more
* efficient as it's been moved to the C level.
*
* @link http://php.net/manual/en/class.apcuiterator.php
* @since APCu 5.0.0
