phpunused

A tool for attempting to identify unreferenced files and unused functions in a PHP codebase.

This is by no means exact, and the output is a report that should be checked manually.

Requirements

• PHP 5.4 (probably)
• grep (so POSIX?)

Usage

Run from the top directory of the project you want to check. Like so:

php ~/repos/phpunused/phpunused.php

State

This is a quick hack to help me analyze a code base. Pull requests are welcome, but apart from that, new features are unlikely.

Possible improvements

• Find references in .js files (ajax calls and such)
• Ignore function references in commented out lines
• Recognise prematurely ended functions (return/exit in front of code)
