PHP is still a dynamic language. PHP 7 gets us scalar typehinting support, which lets us check types at run-time. There are similar annotation based solutions for Ruby as well, which ultimately rely on a lot of Ruby's metaprogramming features. The idea behind these solutions is to have proper type support where you need it. You will have to pry duck-typing from my cold dead hands if you try to remove it from PHP/Ruby completely.
