Well, this doesn't work. The _SESSION thing is something of another ext
module (the session module), and I haven't been able to access anything
from that directly.
But I have worked around that, I can simply check whether a variable is
registered in a session by calling the session_is_registered function
from the session module (by using the call_user_function_ex() function).
I don't think it is very pretty, but it works...
Normal variables can then be fetched by using this zend_hash_find()
function. But if it is an array or a hash the zend_hash_find function
fails. I've got no idea why. And even if it would work I would still
have no clue about how the access the key/value pairs in this
array/hash.
It would be nice it there was some REAL documentation about the API...
