Bug #62344 [NEW]: Class instance unset when running __destruct

From: minghanwu at yahoo dot com Operating system: Debian Linux PHP version: 5.3.14 Package: Scripting Engine problem Bug Type: Bug Bug description:Class instance unset when running __destruct Description: ------------ I use a code like below on a server with php 5.1.6 for long, and the expected result below is the ACTUAL output of the code. Recently I have a new server running 5.3.3 and no luck. The point is the class instance is not able to be referenced when it runs to __destruct(). I use some functions to help object cleaning easier. Any comment or help will be appreciated. Test script: --------------- class Database { function __destruct() { echo "Destroyed Database\n"; }} class Session { private $db; function __construct() { $this->db = new Database(); } function __destruct() { echo "Destroyed Session\n"; check(); } } $sess = new Session(); check(); die(); function check(){ global $sess; if(isset($sess)) echo "yes\n"; else echo "no\n"; } Expected result: ---------------- yes Destroyed Session yes Destroyed Database Actual result: -------------- yes Destroyed Session no Destroyed Database -- Edit bug report at https://bugs.php.net/bug.php?id=62344&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62344&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62344&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62344&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62344&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62344&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62344&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62344&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62344&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62344&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62344&r=support Expected behavior: https://bugs.php.net/fix.php?id=62344&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62344&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62344&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62344&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62344&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62344&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62344&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62344&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62344&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62344&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62344&r=mysqlcfg
