Description:
------------
Howdy,

In APCu (at least in 4.0.2) apc_cache_info and APCIterator are returning an array structure that in not backwards compatible with the original apc functions.  This is on the "user" space apc_cache_info call from the old APC implementation.

The original APC call would return a cache_list entry that had the entry label defined as "info".  APCu changed it to "key".   While I agree with the naming choice, It does break the older APC usage implementations that use apc_cache_info for the the user side cache list.

I found this in Joomla but im sure that there are other php projects that use apc_cache_info in order to find and possibly purge individual user cache entires.

Apparently this has been fixed a long time ago with https://github.com/krakjoe/apcu/commit/66e5883074348b69957aaf82564fc8136fd3561a (lowest version including this commit is 4.0.7), so I'm going to close this issue.
