Sessions and register_long_arrays

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? Marcus -- Marcus Bointon Synchromedia Limited: Putting you in the picture marcus@synchromedia.co.uk | http://www.synchromedia.co.uk
