PHPMD - PHP Mess Detector

Command line usage

Type phpmd [filenamedirectory[,...]]] [report format] [ruleset file], i.e: :

mapi@arwen ~ $ phpmd PHP/Depend/DbusUI/ xml rulesets/codesize.xml
<?xml version="1.0" encoding="UTF-8" ?>
<pmd version="0.0.1" timestamp="2009-12-19T22:17:18+01:00">
  <file name="/projects/pdepend/PHP/Depend/DbusUI/ResultPrinter.php">
    <violation beginline="67"
               ruleset="Code Size Rules"
      This class has too many methods, consider refactoring it.

You can pass a comma-separated string with list of file names or a directory names, containing PHP source code to PHPMD.

The PHPMD Phar distribution includes the rule set files inside its archive, even if the "rulesets/codesize.xml" parameter above looks like a filesystem reference.

Command line options

Using multiple rule sets

PHPMD uses so called rule sets that configure/define a set of rules which will be applied against the source under test. The default distribution of PHPMD is already shipped with a few default sets, that can be used out-of-box. You can call PHPMD's cli tool with a set's name to apply this configuration: :

~ $ phpmd /path/to/source text codesize

But what if you would like to apply more than one rule set against your source? You can also pass a list of rule set names, separated by comma to PHPMD's cli tool: :

~ $ phpmd /path/to/source text codesize,unusedcode,naming

You can also mix custom rule set files with build-in rule sets: :

~ $ phpmd /path/to/source text codesize,/my/rules.xml

That's it. With this behavior you can specify you own combination of rule sets that will check the source code.

Using multiple source files and folders

PHPMD also allows you to specify multiple source directories in case you want to create one output for certain parts of your code :

~ $ phpmd /path/to/code,index.php,/another/place/with/code text codesize

Or use glob pattern: :

~ $ phpmd src/main/php/*/*/*{Renderer,Node}.php text my/rules.xml

Scan input

PHPMD can also read the standard input `stdin`: :

~ $ cat src/MyService.php | phpmd - text my/rules.xml

So the PHP code to be scanned may be generated by an other program not necessarily to be store in file.

Exit codes

PHPMD's command line tool currently defines four different exit codes.


At the moment PHPMD comes with the following renderers:

Some more formats can be obtained by conversion such as:

junit can be obtained using xsltproc` package on the Debian-based systems or `libxslt` on Alpine and CentOS. with this given `junit.xslt config file:

~ $ phpmd src xml cleancode | xsltproc junit.xslt -


For existing projects a violation baseline can be generated. All violations in this baseline will be ignored in further inspections.

The recommended approach would be a phpmd.xml in the root of the project. To generate the phpmd.baseline.xml next to it:

~ $ phpmd /path/to/source text phpmd.xml --generate-baseline

To specify a custom baseline filepath for export:

~ $ phpmd /path/to/source text phpmd.xml --generate-baseline --baseline-file /path/to/source/phpmd.baseline.xml

By default PHPMD will look next to phpmd.xml for phpmd.baseline.xml. To overwrite this behaviour:

~ $ phpmd /path/to/source text phpmd.xml --baseline-file /path/to/source/phpmd.baseline.xml

To clean up an existing baseline file and only remove no longer existing violations:

~ $ phpmd /path/to/source text phpmd.xml --update-baseline
