There's still lots of problems with php like the type system exists now, but doesn't let you put types on containers (arrays, hashmaps etc) so you still can't use the type system to model your app in a way that invalid states throw compiler errors. And it's certainly not ever going to be an algebraic type system. Nothing past the basics make it into php.

They're trailing behind in every way, have you ever looked at a php feature and went "oh god, I want that!"
