How can the values from HTML form inputs be properly assigned to PHP variables using $_POST in a login script?

When submitting a form in HTML, the values from form inputs can be accessed in PHP using the $_POST superglobal. To properly assign these values to PHP variables in a login script, you need to check if the form has been submitted, retrieve the values using $_POST, and assign them to variables. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Use the $username and $password variables in your login script
}
