A common use case for the $_REQUEST superglobal in PHP is to retrieve form data submitted via both GET and POST methods. When a form is submitted, the data is accessible through the $_REQUEST superglobal, regardless of the method used. This allows you to handle form submissions uniformly, regardless of whether the form used the GET or POST method. By accessing the appropriate keys within the $_REQUEST array, you can retrieve and process the form data. Learn more: https://www.php.net/manual/en/reserved.variables.request.php
