Is there a preferred method between using $_REQUEST and $_POST for handling form data in PHP?

When handling form data in PHP, it is generally recommended to use $_POST over $_REQUEST. This is because $_POST is specifically designed for handling form data submitted via the POST method, while $_REQUEST can also include data from other sources like cookies and query strings. By using $_POST, you can ensure that you are only accessing the form data you expect. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data
}
?>
