#37829 [NEW]: set_error_handler used on a $this object causes unexpected result

From: e at osterman dot com Operating system: Debian PHP version: 5.1.4 PHP Bug Type: Class/Object related Bug description: set_error_handler used on a $this object causes unexpected result Description: ------------ This is either a bug in PHP, or an undocumented consequence of the language's design -- either of which should be addressed. If you want to have an object set an error handler to a method in itself, such that when the object passes out of scope or gets destroyed, the __destruct method is called (and previous error handler restored), you cannot do it. The __destruct method is not called until program termination. It appears that by setting the error handler to $this->method, causes $this to become copied rather than referenced. Using Array( &$this, 'method' ) versus Array( $this, 'method' ) has no effect on the outcome -- the problem is "problem" is the same. It's kind'a like creating a scope wormhole, I know, but the documentation doesn't say it's not allowed! :) Reproduce code: --------------- class TestErrorHandler { public function __construct() { print "construct\n"; set_error_handler( Array( $this, 'handler') ); } public function __destruct() { print "destruct\n"; restore_error_handler(); } public function handler() { print "handled\n"; } } $foo = new TestErrorHandler(); $foo = new TestErrorHandler(); print "done.\n"; Expected result: ---------------- construct destruct construct done. destruct Actual result: -------------- construct construct done. destruct destruct -- Edit bug report at http://bugs.php.net/?id=37829&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37829&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37829&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37829&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37829&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37829&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37829&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37829&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37829&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37829&r=support Expected behavior: http://bugs.php.net/fix.php?id=37829&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37829&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37829&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37829&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37829&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37829&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37829&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37829&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37829&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37829&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37829&r=mysqlcfg
