#23441 [NEW]: Session variables and ternary operator

From: jeremy at wdonline dot com Operating system: Windows XP PHP version: 4.3.1 PHP Bug Type: Session related Bug description: Session variables and ternary operator Through many frustrating hours, I think found a bug. The current session documentation offers this example for setting session variables using the $_SESSION array: if (!isset($_SESSION['count'])) { $_SESSION['count'] = 0; } else { $_SESSION['count']++; } This example, of course, works. However, it is common knowledge the the ternary operator can achieve the same results in one line: $_SESSION['count'] = (!isset($_SESSION['count']))?0:$_SESSION['count']++; However, this does not work. The session variable always seems to not be set, as it always retains the value of 0 instead of being incremented. -- Edit bug report at http://bugs.php.net/?id=23441&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=23441&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=23441&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=23441&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=23441&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=23441&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=23441&r=support Expected behavior: http://bugs.php.net/fix.php?id=23441&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=23441&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=23441&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=23441&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=23441&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=23441&r=dst IIS Stability: http://bugs.php.net/fix.php?id=23441&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=23441&r=gnused
