In what scenarios should one consider using $_REQUEST instead of $_GET when retrieving variables in PHP scripts?

Using $_REQUEST instead of $_GET can be useful when you want to retrieve variables from both GET and POST requests without having to differentiate between the two. This can be beneficial in scenarios where you are not sure which method was used to send the data, or when you want to simplify your code by using a single superglobal array to access all request data.

$variable = isset($_REQUEST['variable']) ? $_REQUEST['variable'] : '';
