[![Latest Stable Version](https://poser.pugx.org/sebastian/phpcpd/v/stable.png)](https://packagist.org/packages/sebastian/phpcpd) [![Build Status](https://travis-ci.org/sebastianbergmann/phpcpd.png?branch=master)](https://travis-ci.org/sebastianbergmann/phpcpd) # PHP Copy/Paste Detector (PHPCPD) `phpcpd` is a Copy/Paste Detector (CPD) for PHP code. ## Installation ### PHP Archive (PHAR) The easiest way to obtain PHPCPD is to download a [PHP Archive (PHAR)](http://php.net/phar) that has all required dependencies of PHPCPD bundled in a single file: wget https://phar.phpunit.de/phpcpd.phar chmod +x phpcpd.phar mv phpcpd.phar /usr/local/bin/phpcpd You can also immediately use the PHAR after you have downloaded it, of course: wget https://phar.phpunit.de/phpcpd.phar php phpcpd.phar ### Composer Simply add a dependency on `sebastian/phpcpd` to your project's `composer.json` file if you use [Composer](http://getcomposer.org/) to manage the dependencies of your project. Here is a minimal example of a `composer.json` file that just defines a development-time dependency on PHPCPD: { "require-dev": { "sebastian/phpcpd": "*" } } For a system-wide installation via Composer, you can run: composer global require 'sebastian/phpcpd=*' Make sure you have `~/.composer/vendor/bin/` in your path. ### PEAR Installer The following two commands (which you may have to run as `root`) are all that is required to install PHPCPD using the PEAR Installer: pear config-set auto_discover 1 pear install pear.phpunit.de/phpcpd ## Usage Example ➜ ~ phpcpd /usr/local/src/phpunit/PHPUnit phpcpd 1.4.1 by Sebastian Bergmann.
