PSR (PHP Standards Recommendations)

PSR (PHP Standards Recommendations) are a set of guidelines created by the PHP Framework Interop Group to promote consistent coding practices across PHP projects. They define best practices for organizing code, naming conventions, and technical interfaces, making it easier for developers to read, maintain, and collaborate on PHP applications. Think of PSR as a common language or style guide that helps different PHP tools and frameworks work smoothly together, ensuring greater interoperability and reducing developers' effort in integrating various components.
