What are the best practices for handling form submissions in PHP, specifically in terms of using GET or POST methods?

When handling form submissions in PHP, it is best practice to use the POST method for sensitive data such as passwords, as it is more secure than the GET method which exposes data in the URL. To handle form submissions using the POST method, you can access the form data through the $_POST superglobal array in PHP. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve form data using the $_POST superglobal
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Process the form data as needed
}
