#23097 [NEW]: isset() function returns nothing

From: alex at globaldesign dot ca Operating system: Win XP PHP version: 4.3.0 PHP Bug Type: Output Control Bug description: isset() function returns nothing The isset() function is not working properly with SESSION vars. The following code : <? session_start(); echo isset($_SESSION["not_created_var"]); ?> //Should return '0' Agreed ??? In my case it's returning nothing... I event tried it on my web-hosting server, that is supposed to be properly configured, and still I don't get a '0'. I read Bug #5760 answered by Derick telling that PHP4 returns ""(the empty string) if a var is not set or create, and that '0' is returned if it existed. How come I get a '1' instead ??? -- Edit bug report at http://bugs.php.net/?id=23097&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=23097&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=23097&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=23097&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=23097&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=23097&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=23097&r=support Expected behavior: http://bugs.php.net/fix.php?id=23097&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=23097&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=23097&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=23097&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=23097&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=23097&r=dst IIS Stability: http://bugs.php.net/fix.php?id=23097&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=23097&r=gnused
