Static Code Analysis: Judging a Forest by Its Trees
summary
Automates boring code-review chores by running concrete tools: ECS combines PHP CS Fixer and PHP_CodeSniffer to fix style, PHPStan levels 0–8 to tune strictness, Psalm for extended typing, PHP Insights for CI-friendly colorized output, Deptrac to map dependencies and a migration that cuts wrong module links by ~40% in weeks, PhpMetrics (Twig runs in ~10s) for cyclomatic and coupling scores, custom PHPStan rules enforce an @decoratable contract, and composer-bin-plugin encapsulates tooling so it works locally and in CI.
