Can anyone *really* explain opcode caching with PHP?

Your answer, is my reason :) It is app-dependent, so i never blindly
suggest to someone using it, without a proper undestanding of the system.

Often i have seen badly configured apache server exposing the cached files
to all the users of the system and so on. I see it as a second step in
building an infrastructure. Having said that, i prefer having an
additional layer (like nginx caching or varnish, as already suggested) in
front of the apps. ...But you can obviously have opcode and caching both
working on the same app :)
