PHP PSRs : PSR-1 Basic Coding Standard

PHP Standard Recommendations (PSRs) are PHP specifications that standardize PHP programming concepts. PSR-1 defines basic coding standards. All PHP files must use UTF-8 encoding without a BOM. Files should either declare symbols or cause side effects, not both. Namespaces and class names must follow PSR-4 standards, using StudlyCaps (PascalCase) and proper namespacing. Class constants must be in uppercase with underscores. Method and function names must use camelCase. PSR-1 guidelines ensure interoperability and code quality across PHP projects. Adhering to PSR-1 improves code readability, consistency, and maintainability. These standards promote a unified and standardized approach to PHP coding, reducing errors and facilitating collaboration. PSR-1 is essential for writing high-quality, professional PHP code. By following these guidelines, developers can ensure their code meets industry best practices and is easily understandable and maintainable.
