Question about include ...

Does php retain frequently accessed files in memory when the file is included (include(), include_once(), require(), require_once()) or is it flushed at the end of execution? I'm not talking about including the same file twice during a single execution. I'm saying page executes, file x is included, execution completes -- is file x pulled raw from the file system again on the next execution or is it pulled from memory/cache? If so is there a performance difference?

Stateless.

It remembers nothing of the previous runs.

That's what I thought....

Do accelerator's store that stuff as byte code?

maybe asking in the zend forums would make more sense... seems like a plumbing question!

Seems to me that the engine itself might be responsible for some caching...
