The syntax would allow class constructor parameters to be defined inline in the class declaration (e.g., `class Point(public int $x, int $id = 0) extends Base($id);`), acting as syntactic sugar for the traditional `__construct` method. Classes using primary constructors would not be allowed to also define a `__construct` function; special initialization logic would instead use property hooks. Discussion highlights include a concern that the hooks-only approach prevents use with `readonly` classes, with community members proposing alternative syntaxes to allow an optional constructor body block while keeping construction co-located with the class definition. ## Full article daily.dev links to this article rather than hosting it.
