ID: 45719 Updated by: vrana@php.net Reported By: markvanstraten at gmail dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Windows XP PHP Version: Irrelevant New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "To use the session variables again, session_start() has to be called." Previous Comments: ------------------------------------------------------------------------ [2008-08-05 10:21:20] markvanstraten at gmail dot com changed title to be more descriptive ------------------------------------------------------------------------ [2008-08-05 10:18:44] markvanstraten at gmail dot com Description: ------------ session_destroy() does not only unset the values in the session but disables the session completely, untill another call to session_start() is issued. This is not documented behaviour and should be. It will save people som e time. It is mentioned in the user comments but way down the line, not the first place to search for the description of behaviour. Reproduce code: --------------- <?php session_start(); echo 'current id is ',session_id(),PHP_EOL; //set value in session $_SESSION['foo'] = 'bar'; echo 'value set in session, current content:',PHP_EOL; print_r($_SESSION); //destroy session content session_destroy(); echo 'session destroyed, current content: ',PHP_EOL; print_r($_SESSION); echo 'current id is ',session_id(),PHP_EOL; //regenerate ID? session_regenerate_id(); echo 'regenerated id',PHP_EOL; echo 'current id is ',session_id(),PHP_EOL; //start new session? session_start(); echo 'started new session',PHP_EOL; echo 'current id is ',session_id(),PHP_EOL; //regenerate ID? session_regenerate_id(); echo 'regenerated id',PHP_EOL; echo 'current id is ',session_id(),PHP_EOL; ?> Expected result: ---------------- I would have expected that session_destroy() would only affect the current values of the session. Possibly, i had expected that session_regenerate_id() would (under the surface) call session_start() for me if not already available. Actual result: -------------- session_destroy() destroy's the session with the values and the session_id ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45719&edit=1
