| description.long | A static type checker that analyzes Python code to catch type errors before runtime. Supports gradual typing, allowing you to mix static and dynamic typing and incrementally add type hints to existing codebases. | PHPStan analyzes PHP code to detect bugs and errors before execution. It enhances code reliability by catching a wide range of issues early in development, similar to type checking in compiled languages. |
