improvement: add a filetype hook for PHP

This solve the issue #19
I put it there as an example, it might be better in its own repository.
This way a user will be able to choose to use it or not, which will
allow them to be able to provide their own implementation.

This attempt only deal with methods.
Functions are not part of the PSR-2.
Closures should always have the opening brace on the same line as the
closing parenthesis, this extension is not a CS fixer and therefore as
no reason to deal with them.
