PSR (PHP Standard Recommendation) is a set of standards developed by PHP-FIG (PHP Framework Interop Group) to improve compatibility and interoperability among various libraries and frameworks in the PHP ecosystem. They cover different aspects, from class autoloading to coding styles and interface implementations. Following PSR simplifies code integration and enhances readability.
Some popular PSRs:
- PSR-1: Basic Coding Standard
- PSR-2: Coding Style Guide (now replaced by PSR-12)
- PSR-3: Logger Interface
- PSR-4: Autoloader
- PSR-7: HTTP Message Interfaces
- PSR-12: Extended Coding Style Guide
RFC (Request For Comments) in the context of PHP refers to documents that formally describe proposals for changing or adding new features to the PHP language. The RFC acceptance process involves community discussion, voting, and, if approved, integrating the proposed changes into the next PHP version. It is an open development process that allows any community member to suggest improvements.
Examples of PHP RFCs:
- https://wiki.php.net/rfc/scalar_type_declarations_v5 (Scalar Type Declarations)
- https://wiki.php.net/rfc/return_type_declarations (Return Type Declarations)
