# 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.
