What are the differences between the $_POST and $_GET superglobals in PHP?

The main difference between $_POST and $_GET superglobals in PHP is how they send data to the server. $_POST sends data in the HTTP request body, while $_GET sends data in the URL. $_POST is more secure as it does not expose data in the URL, making it suitable for sensitive information like passwords. To access data sent via $_POST, you use $_POST['key'], while for $_GET, you use $_GET['key']. 

// Example of using $_POST superglobal
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Process the data as needed
}
