Latest Stable Version Build Status

phpcpd is a Copy/Paste Detector (CPD) for PHP code.


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:

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:

php phpcpd.phar


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.
