Any ideas how to fix it? Previous Comments: ------------------------------------------------------------------------ [2016-10-13 22:56:54] yohgaki@php.net @nikic Done. Thanks. ------------------------------------------------------------------------ [2016-10-11 16:26:46] nikic@php.net @yasuo: As noted on the linked PR, it would be good to add an UPGRADING note about this. ------------------------------------------------------------------------ [2016-10-06 08:07:04] yohgaki@php.net Not initializing $_SESSION by 2nd session_start() is not a bug actually, but it should fail to initialize $_SESSION always when session_start() cannot be started. This is the objective for the bug fix commit mentioned. So real bug here is session module initializes $_SESSION even if it failed to start when there is no output before 1st session_start(). This report's bug won't be fixed. I re-opened bug #71038. ------------------------------------------------------------------------ [2016-10-06 08:05:58] yohgaki@php.net Related To: Bug #71038 ------------------------------------------------------------------------ [2016-10-05 15:02:37] cmb@php.net Indeed, it appears to break only if there is already some output before the first session_start(). Try: <?php echo "start\n"; session_start(); $_SESSION['blah'] = 'foo'; var_dump($_SESSION); session_write_close(); session_start(); var_dump($_SESSION); ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
