Phan is a '''[[wp:Static program analysis|static analyzer]]''' for PHP. It apparently originated from Etsy. It will help you write better PHP code. Please note that your source code should follow best practices for directory layout<ref>Essentially, code should live in a 'src' or 'includes' directory; tests go in 'tests' etc. https://www.mediawiki.org/wiki/Best_practices_for_extensions#File_structure</ref>. To use it, you'll need to install the [https://github.com/nikic/php-ast Abstract Syntax Tree] PHP extension. See the [https://github.com/phan/phan/wiki/Tutorial-for-Analyzing-a-Large-Sloppy-Code-Base tutorial for analyzing a large sloppy codebase]
