When Working Code Breaks During Modernization: A Single-File Study on Legacy PHP for LLMs
This study analyzed the problems that arise when LLMs modernize legacy PHP code without project context. Testing 100 files using five different LLMs revealed a strong tendency for these models to unnecessarily break working code. Therefore, it was concluded that modernization evaluation must measure operational preservation separately.
Key takeaways
LLMs tend to unnecessarily break functional code even when lacking project context.
Even the highest-scoring LLM did not achieve higher compatibility than the original code.
LLMs damaged 36%–60% of files, even those that required no changes.
It is essential to measure modernization evaluation separately from operational preservation.
