phpcpd is a Copy/Paste Detector (CPD) for PHP code.
phpcpd should be installed using the PEAR Installer, the backbone of the PHP Extension and Application Repository that provides a distribution system for PHP packages.
Depending on your OS distribution and/or your PHP environment, you may need to install PEAR or update your existing PEAR installation before you can proceed with the following instructions.
sudo pear upgrade PEAR usually suffices to upgrade an existing PEAR installation. The PEAR Manual explains how to perform a fresh installation of PEAR.
The following two commands (which you may have to run as
root) are all that is required to install
phpcpd using the PEAR Installer:
pear config-set auto_discover 1 pear install pear.phpunit.de/phpcpd
After the installation you can find the
phpcpd source files inside your local PEAR directory; the path is usually
