Bug #52754 [NEW]: Array keys in $_SESSION with "!" unsets the whole array in PHP 5.3.3

From: Operating system: Slackware Linux 12 PHP version: 5.3.3 Package: Session related Bug Type: Bug Bug description:Array keys in $_SESSION with "!" unsets the whole array in PHP 5.3.3 Description: ------------ Array keys in $_SESSION containing exclamation marks (!) does not seem to work anymore as of 5.3.3. Have tried key with different characters like #, " and £ - these worked. Using "!" in the key seems not only to be unregistered but also to make the whole $_SESSION to be unset in the next run. This worked before, as in 5.2.x. Test script: --------------- <? # (as we're talking sessions, this example need to be run 2 times to set the session data, push F5...) session_start(); $name = 'hello'; # this does work, uncomment/comment to test $name = 'hello!'; # this does not, uncomment/comment to test echo $_SESSION[$name]; $_SESSION[$name] = 'OK'; ?> Expected result: ---------------- That array keys containing exclamation marks ("!") either give a understandable error or does work as any other key. Actual result: -------------- The whole array is being totally empty if a key containing exclamation mark is entered. -- Edit bug report at http://bugs.php.net/bug.php?id=52754&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52754&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52754&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52754&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52754&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52754&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52754&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52754&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52754&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52754&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52754&r=support Expected behavior: http://bugs.php.net/fix.php?id=52754&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52754&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52754&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52754&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52754&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52754&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52754&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52754&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52754&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52754&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52754&r=mysqlcfg
