PSR-7

PSR-7 is a PHP standard that defines how to handle HTTP messages—requests and responses—in web applications. It provides a consistent way to access and manipulate data like headers, URLs, query parameters, and body content. This makes it easier for developers to build, share, and maintain web components, middleware, and APIs, ensuring interoperability across different PHP frameworks and libraries. In essence, PSR-7 standardizes the structure and behavior of HTTP message objects, promoting cleaner code, better organization, and more flexible web development.
