Previous Comments: ------------------------------------------------------------------------ [2017-12-05 08:38:34] damyon at moodle dot com Description: ------------ When unit testing session-related code in a CLI environment, appropriate PHP ini settings combined with passing false to session_cache_limiter should allow the session handler to be changed even if output has been already sent. With PHP 7.2.0RC5 calling session_set_save_handler prints warning messages, regardless of php ini settings. Very similar previously fixed bug: https://bugs.php.net/bug.php?id=55267 Very similar (but not the same) bugs with php 7.2 https://bugs.php.net/bug.php?id=74936 https://bugs.php.net/bug.php?id=74514 Test script: --------------- <?php S> S> ini_set('session.use_cookies', false); ini_set('session.use_only_cookies', false); ini_set('session.use_trans_id', 1); ini_set('session.cache_limiter', false); session_cache_limiter(false); echo '.'; class MySessionHandler extends SessionHandler { S> S> } $handler = new MySessionHandler(); session_set_save_handler($handler, true); Expected result: ---------------- One single dot of output Actual result: -------------- .PHP Warning: session_set_save_handler(): Cannot change save handler when headers already sent in [filepath]/test.php on line 17 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75628&edit=1
