#45719 [NEW]: session_destroy behaviour documented incomplete

From: markvanstraten at gmail dot com Operating system: Windows XP PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: session_destroy behaviour documented incomplete 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 bug report at http://bugs.php.net/?id=45719&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45719&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45719&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45719&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45719&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45719&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45719&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45719&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45719&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45719&r=support Expected behavior: http://bugs.php.net/fix.php?id=45719&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45719&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45719&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45719&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45719&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45719&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45719&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45719&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45719&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45719&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45719&r=mysqlcfg
