Symfony

Symfony is a PHP framework that provides developers with a collection of components and tools to create and manage robust, scalable, and secure web applications. An important feature of Symfony is its built-in support for the HTTP protocol. This means that developers can access and manipulate HTTP requests and responses. To facilitate these tasks, Symfony provides a set of constants. These constants allow developers to access important HTTP status codes, such as HTTP_OK, HTTP_NOT_FOUND, HTTP_INTERNAL_SERVER_ERROR, and HTTP_METHOD_NOT_ALLOWED, to respond to HTTP requests and responses appropriately. The use of constants in Symfony is therefore an important practice, as they help to make the code more consistent and easier to understand, and also increase the readability and maintainability of the code. In addition, constants help make the code easier to extend and customize, which facilitates the development of scalable and flexible applications.
