You are writing a PHP script and you need to collect form data, but you don't know if the data was sent using the GET or the POST method. How would you do this using the $_REQUEST superglobal?
- Check if the $_REQUEST variable is empty to determine the method.
- Use the isset() function on the $_REQUEST['method'] key.
- Use the $_SERVER['REQUEST_METHOD'] variable to determine the method.
- Use the $_GET and $_POST superglobals separately to handle each method.
To collect form data when you are unsure of the method used (GET or POST), you can use the $_REQUEST superglobal. The $_REQUEST superglobal combines the values of both GET and POST requests. To determine the method, you can use the $_SERVER['REQUEST_METHOD'] variable, which holds the HTTP request method used to access the page. If it contains the value 'GET', the data was sent using the GET method. If it contains 'POST', the data was sent using the POST method.
