Which of the following are common uses of superglobals in PHP?

The correct option is 4. Superglobals in PHP, such as $_POST, $_GET, and $_SERVER, have various common uses. They are commonly used for retrieving form data submitted via an HTTP request, allowing developers to access user-provided values for processing or validation. Superglobals like $_SERVER provide server-related information, which can be useful for tasks such as determining the client's IP address or server environment details. Additionally, the $_SESSION superglobal is widely used for managing session data, enabling features like user authentication and personalization. By utilizing superglobals, PHP developers can build interactive and dynamic web applications that leverage user input and server-related information.
