Edit report at https://bugs.php.net/bug.php?id=80527&edit=1 ID: 80527 Comment by: heavy-traffic-website at yopmail dot com Reported by: heavy-traffic-website at yopmail dot com Summary: Current directory deleted before shutdown_function - File functions affected Status: Not a bug Type: Bug Package: *Directory/Filesystem functions Operating System: Debian 11 PHP Version: 8.0.0 Assigned To: cmb Block user comment: N Private report: N New Comment: I only use PHP-FPM with Haproxy with FCGI, not Apache. I understand there is a little notice that inform it can change during the shutdown function... but... is this normal for our use / need ? Probably not. Why don't you are able to restore the CWD during the shutdown function ? Since i am able to write a one-line fix ; it should be evaluated the feature to not change the CWD during the shutdown function.
