A common use case for the $GLOBALS superglobal in PHP is to access global variables from within a function, which would otherwise be out of the function's ______.
- Local scope
- Global scope
- Class scope
- Static scope
The correct option is 2. A common use case for the $GLOBALS superglobal in PHP is to access global variables from within a function that would otherwise be out of the function's scope. By using $GLOBALS, you can retrieve and manipulate global variables within the function's local scope without the need for the global keyword. This allows you to work with global variables directly within the function, providing more flexibility and convenience. However, it is generally recommended to minimize the use of global variables and consider alternative approaches, such as passing variables as parameters or using object-oriented design principles, for better code organization and maintainability.
