Introducing Tombstones for PHP

Read Original

The article discusses the challenge of safely removing dead code from a large, legacy PHP project. It explains the limitations of static analysis tools and introduces a new concept: "tombstones." These are executable markers placed in suspected dead code that log when they are invoked in production, helping developers confidently identify and remove unused code. The author presents their open-source library, Tombstones for PHP, which implements this functionality.
