What is the difference between using $_GET and $_POST in PHP when receiving form data?

When receiving form data in PHP, the main difference between using $_GET and $_POST is in how the data is sent. $_GET sends the form data as part of the URL, visible to users and limited in size, while $_POST sends the data in the HTTP request body, not visible in the URL and with no size limitations. It is important to choose the appropriate method based on the sensitivity and size of the data being transmitted. 

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