What are the different methods for transferring form data in PHP and what are the potential drawbacks of each?

When transferring form data in PHP, the most common methods are using GET and POST requests. GET requests append form data to the URL, making it visible in the address bar, while POST requests send the data in the background. GET requests are limited in the amount of data that can be sent and are not secure for sensitive information, while POST requests are more secure but can be slower. 

// Using POST method to transfer form data
if($_SERVER["REQUEST_METHOD"] == "POST"){
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the form data
}
