Phalcon can be compiled with PHP8.2, but not executed.
Because I get a lot of errors like:
(This is when the sample program INVO is executed)

Regarding dynamic property in the first half, even if you can trick PHP by preparing a dummy __set() in a class that inherits Phalcon\Mvc\View\Engine\Volt, Use of "self" in callables There is no other way but for to be supported by .zep, so general users cannot do anything.

With the release of Debian 12, the default is PHP 8.2, and even if you're using another distribution, you'll probably be thinking about migrating to PHP 8.2 later this year.
It became difficult to continue using Phalcon.
