What are the differences between using POST and GET methods for passing data in PHP forms?

When passing data in PHP forms, the main differences between using POST and GET methods lie in how the data is transmitted. POST method sends data in the HTTP request body, making it more secure and suitable for sensitive information. GET method appends data to the URL, making it visible in the browser's address bar and more suitable for non-sensitive information. 

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

In the PHP file "process_form.php", you can access the form data using the $_POST superglobal array:

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