Strange behaviour that's taken me ages to track down. I have the
situation where I can create a session, but any changes to it are not
saved. session_write_close() didn't help. Eventually I tracked it
down: if you have register_long_arrays disabled (as is the default in
PHP5), this can happen. Enabling it fixed the problem. A very simple
test case didn't show this problem, so I guess something in my
sessions has a dependency on HTTP_GET_VARS or similar, though these
old-style vars do not appear anywhere in my code... Some of the
libraries I'm using may use them (for example Smarty, though I have
the request_use_auto_globals option enabled for that which should
stop it using them), but nothing to do with them is stored in the
session. If I look at a session file, it's all just scalars and
arrays, no complex types at all, but changing an item in $_SESSION
simply does not get saved back to the session file if
register_long_arrays is enabled.

Anyone else seen this? Any idea why it might be happening?
