https://wiki.php.net/rfc/request-tempnam Just a bit of hand-holding for those who don't remember to clean up their messes.

An obvious question is: When in shutdown should that be called? Assume I have a session handler which uses such a temporary directory which is backed by a custom stream while having a registered shutdown function accessing that session (what did i forget to put into that scenario?) johannes

Is this custom session handler wanting the temporary directory to last between requests? If so then they'd just not use the TEMPNAM_REQUEST flag. If not, then there wouldn't be a problem since RSHUTDOWN happens after calling the methods registered with register_shutdown_function(). -Sara

While I don't think there's anything wrong with this feature, I'm also wondering if maybe people that need this should be using tmpfile() instead? I understand they do slightly different things (in that one gives you an actual file name the other gives you a file handle), but I normally don't need or care about the file name if I expect my temporary file to live and die with the request. Things I usually use tempnam() for are usually things that get born with the request and don't necessarily die with it, like binary storage that's tied to the session (temporary file uploads that might be moved later or deleted). But I don't see any harm in adding this either.

I like it. Also note that it's not always that people “don't remember to clean up their messes” since there are several tricky cases: client closed the connection before the unlink, an exception was thrown... OTOH it may make harder when you actually want to stop an script and inspect it's temp files :)
