What is the difference between using $_REQUEST and $_POST to retrieve form data in PHP?

When retrieving form data in PHP, it is generally recommended to use $_POST over $_REQUEST for security reasons. $_POST only retrieves data sent via the POST method, while $_REQUEST can also retrieve data sent via GET and COOKIE methods, potentially exposing sensitive information. By using $_POST, you can ensure that you are only retrieving the data you expect from the form submission. 

// Using $_POST to retrieve form data
$name = $_POST['name'];
$email = $_POST['email'];
