Oooo... session-level singleton. Not a bad idea, especially in the case of, for example, a User or Visitor model.
Still, your best bet with that is to store the class instance in the $_SESSION variable, and define the __sleep and __wakeup methods accordingly.

What am I missing? Are Singleton instances cleared/collected with subsequent http requests to the same php file?
|
Yes. Yes they are. In fact, between requests, the only things that hang out are the contents of $_SESSION (if session_start() has been called), files, and databases. No other variables are retained. |
