Safe PHP: Exceptions for Core Functions

Safe-PHP is a library that provides exception-throwing versions of core PHP functions. The project aims to address the historical issue of PHP functions returning false on error, which often leads to overlooked error handling. By redefining these functions with exception support, Safe-PHP encourages more robust and readable code. It leverages PHP's exception handling mechanism for improved error management.

Safe-PHP provides a comprehensive set of safe versions for numerous core functions, including file_get_contents and json_decode. It integrates with PHPStan to automatically identify and flag potentially unsafe function calls. Rector, a code refactoring tool, supports automated replacement of false return values with exception handling. The library emphasizes minimal performance impact while greatly enhancing code reliability.

• Core Function Coverage: Provides safe versions for a wide range of core PHP functions, covering common operations like file I/O and JSON handling. Focuses on functions that traditionally return false upon failure.
• PHPStan Integration: Offers a PHPStan rule to identify potentially unsafe function calls, enabling early detection of error-prone code. Provides clear warnings and guidance for safer coding practices.
• Rector Refactoring Support: Includes a Rector configuration file for automated migration of false return values to exception handling. Simplifies the process of upgrading existing codebases to use safer functions.
• Performance: Designed to minimize performance overhead, with measurements indicating a relatively low impact (approximately 700µs per request).
• Extensibility: Designed to be extensible, and future plans involve covering additional core functions and handling edge cases.

The project is actively maintained and has a growing community. Recent commits and issue resolution indicate ongoing development and support. PHPStan integration and Rector support are well established, suggesting a stable and reliable solution.

Developers working with PHP can benefit from Safe-PHP by adopting more explicit and robust error handling practices. It simplifies the process of ensuring functions like file_get_contents and json_decode are used safely. This improves code reliability and reduces the risk of unhandled exceptions that can lead to unexpected behavior. It's particularly valuable when refactoring legacy code or building new applications with a focus on error resilience.
