The term "late static binding" gets mentioned and "static::" is shown in one example, but it doesn't give nearly enough detail about how late static binding works. It only says "From within a method, static::m refers to the member m in the class that corresponds to the class inheritance context in which the method is called", which is vague and lacks a lot important details (for example, how "self::" and "parent::" interact with late static binding). Late static binding is a big enough language feature to deserve its own section. Check out php.net's documentation for late static binding works: http://www.php.net//manual/en/language.oop5.late-static-bindings.php.
