What are the differences between using $_POST and $_GET variables in PHP form handling?

When handling form data in PHP, the main differences between using $_POST and $_GET variables are that $_POST sends data in the HTTP request body, which is not visible in the URL, while $_GET sends data in the URL itself. $_POST is more secure for sensitive information as it is not visible in the URL, while $_GET is easier to use for simple data retrieval as the data is visible in the URL. 

// Using $_POST variables for form handling
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Your form processing logic here
}
