According to the current documentation apc_store() should accept multiple values as the first parameter wrapped in an array. That's what we're using with Lithium. It seems your version doesn't support that feature. We may need to workaround that.

Can you give me the output of php -i | grep -i apc as well as php -v?
Can you var_dump the contents of Libraries::cache()?

Are you using the dev branch? On which commit hash are you on?

I suspect your apc_store is actually zend_shm_cache_store as you're using zend server. Zend Server allows their data store to register apc methods. It seems it doesn't do it fully.

Yeah, the way they do this is kind of evil, actually. IMO this is a bug that should be filed with Zend.

@nateabele Short term I think it's sufficient to push this upstream, mid-term we should consider adding dedicated support for zend's caching methods to the core. I only find it hard to test in an automated way.

I'll open a new ticket for discussing the addition.

@agborkowski As Nate said this is an upstream bug and should be filed in Zend's Bug Tracker. Can you file the following bug with Zend? The bug description should mention:
You are using the zend_datacache.apc_compatibility feature and found out that the apc_store method is not correctly masked. It doesn't support the second syntax (mentioned here http://php.net/apc_store) which creates compatibility problems.

yes ill try push this bug to zend thanx to watch out :)
