PHP caching - out of the box -

I have an application in which I want to cache the parsed pages and DB result. I know about APC (depends on PECL), Peir and other options such as Memkach. But all of them require the installation of additional frameworks and / or packages.

Is there a way that I can use caching (out of box)? Is there anything like Net Application Objects where I can store shared data for all users?

I know PHP does not have any default caching mechanism, similar to that of .NET object is. The only thing that comes near is storing things in the $ _ session / object, but this would mean that caching and global caching per user is not.
