Over the past years, the PHP language and its ecosystem have been greatly improved and got more professional. PHP 8 now supports full type hinting for class properties and methods. IDE such as PHPStorm can provide advanced code writing assistance and code refactoring capabilities. Quality monitoring tools have become more popular and also help toward maintaining hight code quality standards. In this workshop, we’ll dive into legacy code refactoring techniques augmented with the power of famous PHP quality tools such as PHPUnit, PHPStan, Rector, Deptrac, etc. Attendees will learn how they can leverage the power of PHP and its wide Open-Source ecosystem to refactor their legacy code instead of rewriting it from scratch.
