I'm following the example found here http://docs.phalconphp.com/en/latest/reference/models-cache.html#reusable-related-records to cache related models marked as 'reusable'. I've created my own custom model manager and it seems to be working fine, however is there a function or something that I can call to regenerate the key for a subsequent apc_delete() call somewhere else in the project? The $key that comes in looks similar to this:
MyProject\Model\User[[[user_id] = ?0,,O39]]
It's pretty easy to follow, so I could almost make it myself, just I'm confused what that 'O39' on the end is supposed to mean. Any ideas?
