PHP 5.3.0 introduces two new error levels: E_DEPRECATED
and E_USER_DEPRECATED. The
E_DEPRECATED error level is used to indicate that a
function or feature has been deprecated. The
E_USER_DEPRECATED level is intended for indicating
deprecated features in user code, similarly to the
E_USER_ERROR and E_USER_WARNING
levels.
