## What it is
PHPCPD is a Copy/Paste Detector command-line tool for PHP code that identifies duplicated lines and clone classes across a codebase. It is distributed as a PHAR and is now archived and no longer maintained.

## Use cases
- find duplicated code in a php project
- detect copy-pasted functions across files
- measure code duplication percentage in ci
- refactor repeated code blocks in php
- audit legacy php codebase for clones

## When to choose
- you need a simple, fast duplication detector for PHP
- you want a standalone PHAR with no Composer dependency
- you are okay using an unmaintained but stable tool

## When to avoid
- you need actively maintained tooling or support for modern PHP versions
- you need multi-language duplication detection
- you want integration with newer static analysis pipelines

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: developer-tools, code-review, linter
- domain: developer-tools, testing
- platform: cli, php, cross-platform
- tags: code-duplication, copy-paste-detection, static-analysis, php, command-line
