PHP-CS Sniffs

This uses squizlabs/PHP_CodeSniffer. It can detect all issues and fix some of them automatically and is ideal for CI integration (travis, jenkins, circlci etc).


How to use for your project

Most likely you are using composer. As such, put it into the require-dev dependencies:

composer require --dev fig-r/psr2r-sniffer

You can then use it like this:

// Sniffs only
vendor/bin/sniff /path/to/your/files

// Sniffs and fixes
vendor/bin/sniff /path/to/your/files -f

The path is optional if you want to run it on your complete project root dir. It will in this case automatically skip the vendor/ dir.


If you want to run the sniffer over your root src/ folder, run:

vendor/bin/sniff src/

Use -h to list all available options. But with this bin tool the path needs to always come first (it does not work otherwise):

vendor/bin/sniff /path/to/files [optional params]

Useful commands

Verbose output with -v is always useful. With -vv or even -vvv you get even more debug output.

If you want a list of all sniffs in this standard, use -e:

vendor/bin/sniff -e

It will list them all grouped by their standard name and sniff type.

To just run a single sniff, use --sniffs=... and a comma separated list of sniffs, .e.g.:

vendor/bin/sniff --sniffs=PSR2R.Files.EndFileNewline

Usually, if you run it over your complete repository, you would want to exclude dirs like tests/test_files/:

vendor/bin/sniff --ignore=tests/test_files/

Windows usage

For Win OS you should be using \ as separator:

vendor\bin\sniff -v

Include it in your IDE via hotkey

E.g. for PHPStorm:

  • Open Settings -> Tools -> External Tools
  • Add a new tool named "cs-sniffer" and set Program to $ProjectFileDir$/vendor/bin/phpcs, Parameters to --standard=$ProjectFileDir$/vendor/fig-r/psr2r-sniffer/PSR2R/ruleset.xml -p $FilePath$ and Working directoy to $ProjectFileDir$.
  • Add a new tool named "cs-fixer" and set Program to $ProjectFileDir$/vendor/bin/phpcbf, Parameters to --standard=$ProjectFileDir$/vendor/fig-r/psr2r-sniffer/PSR2R/ruleset.xml -v $FilePath$ and Working directoy to $ProjectFileDir$.
  • Optionally uncheck "Open console" if you don't want to see any output here for the fixer.
  • Now set up your hotkeys under Settings -> Keymap (search for cs-sniffer and cs-fixer). E.g. Control + Comma for sniffing, and Control + Dot for fixing.
Hook it into your IDE for live-correction

You can also easily make a "watcher" for your IDE, so any file you work on, will be auto-corrected when (auto-)saving. But here you should better only whitelist certain sniffs that only add things and don't remove anything.

Note: For PHPStorm, for example, make sure you switch Show Console to never to not be disturbed by it all the time.

Writing new sniffs

You can contribute by adding new sniffs as per PSR-2-R standard.

Tokenizing Tool

It really helps to see what the code looks like for the sniffer. So we can parse a PHP file into its tokens using the following tool:

bin/tokenize /path/to/file

(If you run this from your application, it will have to be run as vendor/bin/tokenize)

With more verbose output:

bin/tokenize /path/to/file -v

For a file MyClass.php it will create a token file MyClass.tokens.php in the same folder.

Example output of a single line of PHP code:

    protected static function _optionsToString($options) {

Using the verbose option:

    protected static function _optionsToString($options) {
// T_WHITESPACE (935) code=379, line=105, column=1, length=1, level=1, conditions={"9":358}, content=`\t`
