Problem

How to use the phpcpd command: A copy and paste detector for PHP code. More information: <https://github.com/sebastianbergmann/phpcpd>.

Solution

phpcpd — A copy and paste detector for PHP code. More information: <https://github.com/sebastianbergmann/phpcpd>.

Analyze duplicated code for a specific file or directory:

phpcpd {{path/to/file_or_directory}}

Analyze using fuzzy matching for variable names:

phpcpd --fuzzy {{path/to/file_or_directory}}

Specify a minimum number of identical lines (defaults to 5):

phpcpd --min-lines {{number_of_lines}} {{path/to/file_or_directory}}

Specify a minimum number of identical tokens (defaults to 70):

phpcpd --min-tokens {{number_of_tokens}} {{path/to/file_or_directory}}

Exclude a directory from analysis (must be relative to the source):

phpcpd --exclude {{path/to/excluded_directory}} {{path/to/file_or_directory}}

Output the results to a PHP-CPD XML file:

phpcpd --log-pmd {{path/to/log_file}} {{path/to/file_or_directory}}
