#44840 [NEW]: objects destroyed on callback functions

From: fabiovh at gmail dot com Operating system: RHEL5 PHP version: 5.2.5 PHP Bug Type: Output Control Bug description: objects destroyed on callback functions Description: ------------ It is already filed as Bug #39693, but I did not find a way to reopen it or comment on it. I believe it has been marked as bogus in mistake, or at least with not enough pondering about the problem. I'm sure this wasn't the behavior in earlier versions of PHP 5, since my code just broke with the upgrade, exactly because objects are now destroyed, but it worked fine before. At least mentioning this new behavior in the docs (on ob_start) would be sensitive. But to me it's waaay weird that everything else works in those callback functions, except objects. I think it's pretty severe, since this change of behavior breaks compatibility and makes output buffer processing useless for OO applications. I had to change a lot of code - for the worse - to make it compatible. Reproduce code: --------------- <? ob_start('callback'); class Test { function method() { return 'cow'; } } $test = new Test(); function callback ($content) { global $test; return 'm:'.$test->method(); } ?> Expected result: ---------------- cow Actual result: -------------- [none] httpd: PHP Fatal error: Call to a member function method() on a non-object in (...).php on line 16 -- Edit bug report at http://bugs.php.net/?id=44840&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44840&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44840&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44840&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44840&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44840&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44840&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44840&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44840&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44840&r=support Expected behavior: http://bugs.php.net/fix.php?id=44840&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44840&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44840&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44840&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44840&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44840&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44840&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44840&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44840&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44840&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44840&r=mysqlcfg
