oop - Default visibility of class methods in PHP

Question

I looked at the manual, but I can't seem to find the answer.

What is the default visibility in PHP for methods without a visibility declaration? Does PHP have a package visibility like in Java?

For example, in the following code, is go() public or private?

class test {
  function go() {
  }
}

The reason I asked is that I've seen many constructors code written as function __construct() and some as public function __construct(). Are they equivalent?

Answer 1

Default is public.

Class methods may be defined as public, private, or protected. Methods declared without any explicit visibility keyword are defined as public.
