I am searching for days now to get a concrete example of how to use the __sleep() and __wakeup() function in a class to restore a databaseconnect ion when passing an object from one page to another by putting it in a session-variable.

What I already know is that you should load the class before the session_start() function etc... What I DO NOT know is how the concrete code in the __sleep() and __wakeup() functions should be in order...
