"Fixed" might be strong, since PHP rightly values backwards compatibility highly, but it is true that most of these issues aren't anything you need to think about when developing in recent PHP versions with recent frameworks. "Recent" here means roughly "from within the last eight years". That said, there are many, many ancient PHP codebase out there that depend on all the worst features of ancient versions and are not going to get fixed any time soon. The fact that things can be done sanely now doesn't really fix the decades where they couldn't.
