Note Submitter: dk at brightbyte dot de ---- Sometimes, you want to "catch" only some errors, and let the default handler deal with the result. I just found out that (at least in PHP 5), the default handler will be called if you return false (not 0 or NULL or '', but false) from your custom handler. This allows for "chaining" handlers. The fature was suggested in this thread: http://www.zend.com/lists/php-dev/200405/msg00491.html - the initial suggestion was to call the default handler if true is returned, but this was changed later on, apperently.
