Usage

How to use in projects

Make sure you include the sniffer as require-dev dependency:

composer require --dev php-collective/code-sniffer

Then set up a phpcs.xml file in your project ROOT, e.g.:

<?xml version="1.0"?>
<ruleset name="your-app-name">
    <file>src/</file>
    <file>tests/</file>

    <rule ref="vendor/php-collective/code-sniffer/PhpCollective/ruleset.xml"/>

    <!-- Here you can add more or also silence existing ones -->
</ruleset>

How to use in any project

You can manually invoke the phpcs/phpcbf commands:

vendor/bin/phpcs
vendor/bin/phpcbf

The command phpcs just sniffs, phpcbf fixes.

It is recommended to set up composer scripts to have shortcuts:

"scripts": {
    "cs-check": "phpcs -nps",
    "cs-fix": "phpcbf -nps"
}

Then you can run composer cs-c and composer cs-f and don't have to worry about the acronyms.

Standards

You can always switch the standard to the stricter one named PhpCollectiveStrict. It is an extension of the PhpCollective standard with its own (strict) sniffs added on top.

How to include in your IDE

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/php-collective/code-sniffer/PhpCollective/ruleset.xml -p $FilePath$ and Working directory to $ProjectFileDir$.
• Add a new tool named "cs-fixer" and set Program to $ProjectFileDir$/vendor/bin/phpcbf, Parameters to --standard=$ProjectFileDir$/vendor/php-collective/code-sniffer/PhpCollective/ruleset.xml -v $FilePath$ and Working directory to $ProjectFileDir$.
• Remove the "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.

You can also set up file watchers, but here you should better only whitelist certain sniffs that only add things and don't remove anything.

How to configure the default rule set

In order to simplify command line interface, phpcs allows to specify default rule set in and standards path the following way.

Assuming the following directory structure:

vendor/php-collective/code-sniffer/                          # Base directory
                           |_ PhpCollective/                # Rule set name
                                      |_ ruleset.xml  # Rule set

The base directory and rule set can be used in configuration now.

vendor/bin/phpcs --config-set installed_paths vendor/php-collective/code-sniffer/
vendor/bin/phpcs --config-set default_standard PhpCollective

You might need to specify full directory path. Now the tools can be used without --standard switch.

Make sure that you include the PhpCollective core standard ruleset in your custom one, e.g.:

<?xml version="1.0"?>
<ruleset name="PhpCollectiveProject">
    <description>
        PhpCollective Coding Standard for Project.
        Extends main PhpCollective Coding Standard.
        All sniffs in ./Sniffs/ will be auto loaded
    </description>

    <rule ref="vendor/php-collective/code-sniffer/PhpCollective/ruleset.xml"/>

    <!-- Define your own sniffs here -->
</ruleset>

If you want to use the PhpCollectiveStrict standard in your project, you should replace the string:

<rule ref="vendor/php-collective/code-sniffer/PhpCollective/ruleset.xml"/>

with this one:

<rule ref="vendor/php-collective/code-sniffer/PhpCollectiveStrict/ruleset.xml"/>
