Trapping Fatal Errors

Has anyone come up with a way to trap and log fatal PHP errors? I understand how to implement and use a custom error handler for all other error conditions, but there doesn't appear to be any way to log fatal errors (such as a parse error or errors resulting from declaring the same function name multiple times). I was only able to unearth one thread on this list pertaining to this topic and the question never seemed to get answered. If you're interested an archive of that thread is located at: http://marc.theaimsgroup.com/?l=php-general&m=98803976202673&w=2 Thanks. - Jamie
