What is the difference between using $_GET and $_POST in PHP forms?

When submitting form data in PHP, you can use either the $_GET or $_POST superglobals to retrieve the form data. The key difference between them is that data sent using the GET method is visible in the URL, while data sent using the POST method is not. It is generally recommended to use the POST method when dealing with sensitive information like passwords, as it provides a more secure way of transmitting data. 

<form method="post" action="process_form.php">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="Submit">
</form>
```

```php
$username = $_POST['username'];
$password = $_POST['password'];
