Yes, I am also able to reproduce this in the browser using both 5.3.1 as well as 5.3.0 on Windows using IIS. Seems like a bug. You may like to file the bug at http://bugs.php.net.

The manual state that exception throw from __autoload could be catched with try.. catch statement same as the normal flow. But I'can archive that even I have copied the same sample code from the manual. Here are the code segment. [[[ function __autoload($name) { echo "Want to load $name.\n"; throw new Exception("Unable to load $name."); } try { $obj = new NonLoadableClass(); } catch (Exception $e) { echo $e->getMessage(), "\n"; } ]]] Are there anyone experienced this or not ? Thanks in advance ! Regards, Eric,
