Clean Code: Refactoring Legacy Code in PHP

Google Meet link will be updated soon A significant amount of time in software development projects is not spent on developing new code, but rather on maintaining and extending existing code. The software craftspeople at Nelkinda understand the importance of maintainable code for the success of any software development project. Clean code reduces cost and effort for maintenance. During this meetup, Christian Hujer will walk the audience through the refactoring of a piece of PHP code to make it gradually more maintainable. This will be interspersed with questions, discussions, and explanations about various approaches. Learning for Participants • Clean Code Principles • SOLID Principles (especially OCP) • Design Patterns (especially Strategy) • The Two Values of Software • The Four Design Smells • Dealing with Legacy Code Demo You will be walked through the Expense Report example. And in case you know it from Robert C. Martin, you might be surprised by the differences in this approach and solution.
