phpcpd
phpcpd is a Copy/Paste Detector (CPD) for PHP code.
The goal of phpcpd is not to replace more sophisticated tools such as phpcs, pdepend, or phpmd, but rather to provide an alternative to them when you just need to get a quick overview of duplicated code in a project.
Requirements
- The tokenizer extension is required.
Installation
phpcpd should be installed using the PEAR Installer. This installer is the backbone of PEAR, which provides a distribution system for PHP packages, and is shipped with every release of PHP since version 4.3.0.
The PEAR channel (pear.phpunit.de) that is used to distribute phpcpd needs to be registered with the local PEAR environment. Furthermore, a component that phpcpd depends upon is hosted on the eZ Components PEAR channel (components.ez.no).
sb@ubuntu ~ % pear channel-discover pear.phpunit.de
Adding Channel "pear.phpunit.de" succeeded
Discovery of channel "pear.phpunit.de" succeeded
sb@ubuntu ~ % pear channel-discover components.ez.no
Adding Channel "components.ez.no" succeeded
Discovery of channel "components.ez.no" succeeded
This has to be done only once. Now the PEAR Installer can be used to install packages from the PHPUnit channel:
sb@ubuntu ~ % pear install phpunit/phpcpd

install ok: channel://components.ez.no/ConsoleTools-1.6
install ok: channel://pear.phpunit.de/File_Iterator-1.1.0
install ok: channel://pear.phpunit.de/phpcpd-1.3.0
After the installation you can find the phpcpd source files inside your local PEAR directory; the path is usually /usr/lib/php/PHPCPD.
