An opinionated ruleset focused on strict types. Suitable for both applications and packages.

1. Install the package via composer by running:

composer require --dev interaction-design-foundation/coding-standard

2. Add composer scripts into your composer.json:

"scripts": {
  "cs:check": "phpcs -p -s --colors --report-full --report-summary",
  "cs:fix": "phpcbf -p --colors"
}

3. Create file phpcs.xml on base path of your repository with content

<?xml version="1.0"?>
<ruleset name="My Coding Standard">
    <!-- Include all rules from the IxDF Coding Standard -->
    <rule ref="IxDFCodingStandard"/>

    <!-- Paths to check -->
    <file>app</file>
    <file>config</file>
    <file>database</file>
    <file>lang</file>
    <file>routes</file>
    <file>tests</file>
</ruleset>

• To run checks only:

composer cs:check

• To automatically fix many CS issues:

composer cs:fix

Disable parts of a file:

$xmlPackage = new XMLPackage;
// phpcs:disable
$xmlPackage['error_code'] = get_default_error_code_value();
$xmlPackage->send();
// phpcs:enable

Disable a specific rule:

// phpcs:disable Generic.Commenting.Todo.Found
$xmlPackage = new XMLPackage;
$xmlPackage['error_code'] = get_default_error_code_value();
// TODO: Add an error message here.
$xmlPackage->send();
// phpcs:enable

Ignore a specific violation:

$xmlPackage = new XMLPackage;
$xmlPackage['error_code'] = get_default_error_code_value();
// phpcs:ignore Generic.Commenting.Todo.Found
// TODO: Add an error message here.
$xmlPackage->send();

New rules or Sniffs may not be introduced in minor or bugfix releases and should always be based on the develop branch and queued for the next major release, unless considered a bugfix for existing rules.

Rules can be added, excluded or tweaked locally, depending on your preferences. More information on how to do this can be found here:
