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) 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 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.
