#39693 [NEW]: objects destroyed, but not always on callbacks functions

From: guessousmehdi at hotmail dot com Operating system: windows PHP version: 5.2.0 PHP Bug Type: Output Control Bug description: objects destroyed, but not always on callbacks functions Description: ------------ When I terminate a script by an exit, before end of execution, ob_start allows to to invoke a callback function. From this callback function, I cannot access to an object (in source example:$t1) previously initiated in the script. However, if I save a dummy copy of that object in a new variable (for instance $t2), then it work as expected. In the source example, just uncomment the line "$t2=$t1;" to see what I mean. I works normally in previous version of php (php 4 and first releases of 5) I cannot remplace the exit at the end by an ob_flush(), because I'm including a big script in my real work, which is much more complex than the example I provide. Reproduce code: --------------- <?php class test{ function nice_string(){ return "hello world, how are you ?"; } } $t1 = new test(); // the following commented line makes a difference //$t2=$t1; function callbackfunc($output){ global $t1; $output ="chocolate<br>". $output . "<br>". $t1->nice_string(); return "$output"; } ob_start('callbackfunc'); echo "what a nice day"; exit(); ?> Expected result: ---------------- should output: chocolate what a nice day hello world, how are you ? Actual result: -------------- output nothing, blank page, probably a fatal error without any indication about it. Uncommenting line $t2=$t1 and it works fine again. -- Edit bug report at http://bugs.php.net/?id=39693&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39693&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39693&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39693&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39693&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39693&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39693&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39693&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39693&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39693&r=support Expected behavior: http://bugs.php.net/fix.php?id=39693&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39693&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39693&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39693&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39693&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39693&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39693&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39693&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39693&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39693&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39693&r=mysqlcfg
