A simple question: where can I find out documentation on what's in the global variable/object $SESSION? More specifically, I'm trying to find the current session ID. I have tried:
var_dump($SESSION);
and got output such as that below, which takes some parsing and doesn't appear to mention the session id.
I've searched TFM, TFFAQs, TFFora, and even a famous Internet search engine, with various search strings, very likely the wrong ones. I can find info on various other global variables in the Core APIs section, but can't find a thing on $SESSION. I suspect that $SESSION is an object which aliases the PHP global variable $_SESSION, which is fine, but I could really do with knowing what its keys are. For instance, the /course/changenumsections.php script requires a valid session ID.
Still burrowing through the dense undergrowth...
