Edit report at https://bugs.php.net/bug.php?id=79267&edit=1 ID: 79267 Comment by: hennadii dot panasenko at gmail dot com Reported by: williamdes at wdes dot fr Summary: to much setcookie calls crashes the script Status: Verified Type: Bug Package: Reproducible crash Operating System: devilbox/php-fpm:7.3-mods PHP Version: Irrelevant Block user comment: N Private report: N New Comment: The 502 is coming from php-fpm (php-fpm is crashing)? After a long time debug i've found that issue is coming from the method of deleting a cookie. In my project i need to update cookie domain from parent to child. To do this, i previously delete the cookie, and on the next line set it again with the new credentials. Non-working code is: setcookie('COOKIENAME', '', 0, '/', 'myhost.com', true, false); setcookie('COOKIENAME', 'COOKIEVALUE', 0, '/', 'sub.myhost.com', true, false); I've found that while i'm deleting a cookie, there is no need to set any additional data, but only name, value and zero-time. Any additional credentials are cause the 502 error. Also, no cookie-name or cookie-value matters. Working code is: setcookie('COOKIENAME', '', 0); setcookie('COOKIENAME', 'COOKIEVALUE', 0, '/', 'sub.myhost.com', true, false); Hope, it will help.

I called this a crash because I assumed that is the case or a response would be sent if the process did end normally ------------------------------------------------------------------------ [2020-02-24 12:36:52] hennadii dot panasenko at gmail dot com I'm facing the same issue while trying to send extra one cookie using the code setcookie('GLSU', $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 0, '/' , $_SERVER['SERVER_NAME'], true, true); When I commented out one of the cookies (other, not this), all works fine. No 'buben-dances' helped to solve the issue, not changing the cookie data, nor cookie name or any other credentials. It looks like only cookie count matters. If needed, I'm ready to help to reproduce it. ------------------------------------------------------------------------ [2020-02-24 12:10:19] nikic@php.net With FPM I do see a "502 bad gateway", though no actual crash. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
