If you do this from the constructor of an Exception, $this references the Exception object. This is tested on my dev machine running Windows 7, IIS7.5 and PHP 5.3.2 as well as our test server running Windows Server 2008, IIS7 and PHP 5.3.2 Test script: --------------- <?php class ExtendedException extends Exception { public function __construct($message, $code) { parent::__construct($message, $code); Log::Write("Hello!"); } } class Log { // Note this method is not marked static public function Write($string) { print_r($this); } } try { throw new ExtendedException(); } catch (Exception $e) { } ?> Expected result: ---------------- Actual result: -------------- ExtendedException Object ( [message:protected] => [string:Exception:private] => [code:protected] => 0 [file:protected] => D:\Public\Innovirt\bugtest.php [line:protected] => 18 [trace:Exception:private] => Array ( ) [previous:Exception:private] => ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51406&edit=1
