[RFC] Add get_error_handler(), get_exception_handler() functions

Hi, At the moment, there is no direct way to fetch the currently registered error or exception handlers. Users who need to inspect these handlers must resort to a workaround that temporarily sets a new handler and then immediately restores the previous one: $current_error_handler = set_error_handler('valid_callback'); restore_error_handler(); This feels hackish and is error-prone. I would like to propose the addition of two new functions: get_error_handler(), get_exception_handler() to address this: https://wiki.php.net/rfc/get-error-exception-handler Best Regards, Arnaud
