Implementation Guidelines

• Composer: Always commit composer.lock for applications. Use composer audit and composer install in CI (not update) for locked versions.
• Autoloading: Strictly enforce PSR-4 autoloading in composer.json (e.g., "psr-4": {"App\\": "src/"} — ensure backslashes are escaped). Run composer dump-autoload after changes.
• Static Analysis: Mandate PHPStan (Level 5+) or Psalm in CI. Install via composer require --dev phpstan/phpstan. Create phpstan.neon with parameters: { paths: [src], level: 6 }. Run via vendor/bin/phpstan analyse.
• Linting: Automate PSR-12 standards via composer require --dev friendsofphp/php-cs-fixer. Configure in .php-cs-fixer.php with $config->setRules(['@PSR12' => true]). Use php-cs-fixer to enforce standards.
• Execution: Use PHP 8.1+ to leverage performance improvements (JIT, OpCache).
• Scripts: Define standard task "scripts": { in composer.json ("analyze": "phpstan analyse", "test": "phpunit", "check": ["@fix", "@analyze", "@test"]}). Run with composer check.
• Debugging: Use Xdebug for local development only. Remove xdebug.so from prod config or set XDEBUG_MODE=off in production.
• Docker: Use Multi-stage Dockerfiles with php:8.x-fpm or php:8.x-cli base images.

Anti-Patterns

• No manual require: Use Composer PSR-4 autoloading only.
• No blind composer updates: Review composer.lock diff first.
• No Xdebug in production: Disable the extension in prod env.
• No vendor/ in git: Exclude via .gitignore; use Composer.
