Answer 1

With standard PHP sessions, there's no way to track when a particular session expires. the garbage collector has a random chance of being executed during EVERY invocation of a php script, and it will not report what it's doing, or what sessions were pruned.

If you want to track which sessions were expired and do extra cleanup when that happens, you'll have to roll your own session handler: session_set_save_handler()
