[symfony.com/doc/../contributing/../standards] Use underscores for option names and parameter name

[sruj]

http://symfony.com/doc/current/contributing/code/standards.html#naming-conventions

Use underscores for option names and parameter names;

//line 95: 
private function reverseBoolean($value = null, $theSwitch = false)

So what is the correct rule?

@sruj I'm sorry for the confusion. The underscores are for the config options and params, not for the PHP arguments. In #7957 I'm trying to fix this with a minor reword.

I'm reopening the issue because we close them automatically when the related pull request is merged. Thanks!
