From: hfuecks at phppatterns dot com Operating system: Windows 2000 PHP version: 5.0.1 PHP Bug Type: Zend Engine 2 problem Bug description: __destruct called twice with ze1_compatibility_mode = On
Description: ------------ Using unmodified copy on php.ini-recommended (no extensions loaded etc.). Able to reproduce this problem with the Apache SAPI, CLI and CGI SAPIs. With zend.ze1_compatibility_mode = On class destructors get called twice, once directly after the constructor. With zend.ze1_compatibility_mode = Off (no other modifications to runtime) problem disappears (destructor called correctly). This seems to have been reported before (not enough info): http://bugs.php.net/bug.php?id=27698 Have yet to confirm whether this in Windows specific (more from Linux when I get there...) Reproduce code: --------------- <?php class Test { function __construct() { echo __METHOD__."\n"; } function someMethod() { echo __METHOD__."\n"; } function __destruct() { echo __METHOD__."\n"; var_dump(debug_backtrace()); } } $T = new Test(); $T->someMethod(); ?> Expected result: ---------------- Test::__construct Test::someMethod Test::__destruct array(1) { [0]=> array(4) { ["function"]=> string(10) "__destruct" ["class"]=> string(4) "Test" ["type"]=> string(2) "::" ["args"]=> array(0) { } } } Actual result: -------------- Test::__construct Test::__destruct array(2) { [0]=> array(5) { ["file"]=> string(20) "D:\php\test\test.php" ["line"]=> int(18) ["function"]=> string(10) "__destruct" ["class"]=> string(4) "Test" ["type"]=> string(2) "::" } [1]=> array(3) { ["file"]=> string(20) "D:\php\test\test.php" ["line"]=> int(18) ["function"]=> string(7) "unknown" } } Test::someMethod Test::__destruct array(1) { [0]=> array(4) { ["function"]=> NULL ["class"]=> string(4) "Test" ["type"]=> string(2) "::" ["args"]=> array(0) { } } } -- Edit bug report at http://bugs.php.net/?id=29756&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29756&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29756&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29756&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29756&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29756&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29756&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29756&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29756&r=support Expected behavior: http://bugs.php.net/fix.php?id=29756&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29756&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29756&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29756&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29756&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29756&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29756&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29756&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29756&r=float
