Php Modernization

This is a comprehensive PHP modernization workflow that brings legacy codebases up to PHP 8.1 through 8.5 standards. It bundles introspection scripts, reference docs for everything from property hooks to PSR-15 middleware, and a modernize_loop.py that runs Rector, PHPStan, and PHP-CS-Fixer in coordination. The guardrails are the real value here: it won't let you apply readonly to Doctrine entities, won't raise PHPStan levels without regenerating baselines, and enforces strict_types everywhere. Built by Netresearch, it includes 20+ reference files covering edge cases like Doctrine embeddables, API Platform quirks, and the PHPUnit 12 to 13 mock versus stub distinction. Use it when you need to modernize a PHP project methodically instead of guessing which 8.x features are safe to adopt.
