PHP Copy/Paste Detector (PHPCPD)

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:

$ wget
$ 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
$ php phpcpd.phar


You can add this tool as a local, per-project, development-time dependency to your project using Composer:

$ composer require --dev sebastian/phpcpd

You can then invoke it using the vendor/bin/phpcpd executable.
