PHPCS Check and Fix

This project uses PHP CodeSniffer (PHPCS) with the FigLab Coding Standard (which extends the IxDF Coding Standard, built on PSR + Slevomat rules). The config lives in phpcs.xml at the project root.

Commands

• Auto-fix: composer cs:fix — runs PHPCBF to automatically fix what it can
• Check: composer cs:check — runs PHPCS to report remaining violations

Workflow

Follow this exact sequence:

1. Run composer cs:fix to auto-fix as many issues as possible. This handles spacing, bracket placement, import ordering, and other mechanical fixes.

2. Run composer cs:check to see what remains. Parse the output carefully — it shows the file path, line number, error type, and the sniff name (e.g., SlevomatCodingStandard.Complexity.Cognitive.ComplexityTooHigh).

3. Fix remaining issues manually, one by one. The approach depends on the violation type — see the section below.

4. Re-run composer cs:check after manual fixes to confirm everything passes. If new issues appear, fix those too.

Handling Common Remaining Issues

After composer cs:fix, these are the violations that typically need manual attention:

Cognitive Complexity (SlevomatCodingStandard.Complexity.Cognitive.ComplexityTooHigh)

The project has a warning threshold of 7 and an error threshold of 10.

• If the method is only slightly over the threshold (e.g., complexity 8-11 on a method that's inherently branchy), add an inline ignore directive on the line above the method declaration:

// phpcs:ignore SlevomatCodingStandard.Complexity.Cognitive.ComplexityTooHigh
public function handleComplexScenario(): void
{
    // ...
}

• If the method is significantly over (complexity 12+), consider refactoring: extract helper methods, use early returns, or simplify conditional logic. Only add the ignore directive if refactoring would make the code less readable.

Missing Type Hints

Add proper PHP type declarations. Use union types (string|int) or nullable types (?string) where appropriate. For arrays, add PHPDoc with array shape when the structure is known:

/** @param array{name: string, email: string} $data */
public function process(array $data): void

Function/Class Length

If a function or class is too long, look for opportunities to extract methods or break the class into smaller focused classes. For test files, these rules are already excluded in phpcs.xml.

Unused Function Parameters

Already excluded for Policy classes and factories in phpcs.xml. For other files, either use the parameter or prefix with underscore if it's required by a parent signature.

Line Length

The limit is 160 characters (absolute max 200). Break long lines at logical points — method chains, array entries, or string concatenation.

Scoping to Specific Files

When you only changed a few files, you can target the check to just those files instead of the entire project:

vendor/bin/phpcs --standard=phpcs.xml path/to/File.php
vendor/bin/phpcbf --standard=phpcs.xml path/to/File.php

This is faster than running the full project scan. Use this when fixing style issues in files you've just edited.

CI Integration

The GitHub Actions workflow (.github/workflows/phpcs.yml) runs on every push:

1. Auto-fixes with composer cs:fix and commits the result
2. Runs composer cs:check — failures show as annotations in the PR

So if you fix everything locally, CI will pass cleanly.
