/**

|
* 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.
