Hello, I am writing a book on PHP with Andrei Zmievski and I asked him a question on how resources are handled and he suggested posting the question here.

My suspicion is that persistent resources are only cleaned up when the child process dies, while non-persistent resources are closed immediately at the end of the page/script. Does anyone know the correct answer? If you can spare the time, I would be grateful for an answer to the following questions too: 2. If resources are not cleaned up until the apache child process dies, what will happen in multi-threaded servers like Apache 2 and IIS? 3. Are persistent resources locked exclusively by an executing script until the script completes when the resources become available for other scripts, or can persistent resources be shared by multiple concurrent scripts?
