I gave the new (alpha release) PHP formatter in the Prettier suite a try:
https://prettier.io/blog/2018/04/09/plugin-php-0.1.html
Prettier is a popular package for Javascript and other languages, and it has a package to integrate with Sublime Text. To get started, I installed the package globally:
npm install --globally prettier/prettier prettier/plugin-php
and tried it on some of our Internal Transfer code with
prettier filename.php --write
I quickly found some formatting errors with embedded <?php ?> tags, and found the problem I ran into was already in the issue queue. This package looks promising, but it’s not at all ready for production work at this time.
