Hi,
The good news is, you're not the only person who wants this, or the first to suggest it. There
was a mailing list thread about it 18 months ago [1] followed up by an RFC last April. [2][3]
The bad news is that there hasn't been much movement since then. The best thing to do is to
read through those discussions, and maybe catch up with David and Guilliam who wrote the RFC, then
post to the list to restart the discussion.

Hi Karolis,
Send an e-mail to internals@lists.php.net to measure reaction to your intended proposal. State who
would implement the feature, or whether the proposal is only a âconceptâ. Proceed with an
RFC if feedback is not negative or if a detailed RFC will clarify the proposal. Mail list
subscription is at http://php.net/mailing-lists.php.
(Reminder: always "bottom post" your replies. Never âtop postâ.)
For detailed RFC Process instructions please see:

Description:
------------
Currently the type casts allowed are: (int), (bool), (string), etc. It would be very convenient to
have their nullable counterparts, i.e.: (?int), (?bool), (?string), etc.
Generally speaking the idea is to be able to do this:
$nullable_int = (?int) $nullable_string;
which would be an equivalent of this:
$nullable_int = is_null($nullable_string) ? null : (int) $nullable_string;
