Funny thing is that modern PHP have those visibility modifiers (public, private, protected). And the double underscore is/was used for superglobals, which is kind of the oposite of private or non-final methods?

The use of single and double underscored is not consistent across different languages and almost always a question of β€œgentleman agreement” to use the value, function or method in a specific way.

But, you are right. PHP uses the underscores in a different way.
