如何在PHP中将方法声明为公共但非静态？

Question

The question is in the title.

Answer 1

They are non-static by default:

public function method() {

}

You will get an E_STRICT if you call it statically, but I don't think you can easily enforce that it can only be called on an instance - if you try to check $this I think you will get an error. You could do isset($this) as Artefacto says and throw an exception if it isn't set.
