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

When submitting a form in PHP, the main differences between using the POST and GET methods are how the data is sent and how it is visible in the URL. The POST method sends form data in the HTTP request body, making it more secure for sensitive information like passwords. On the other hand, the GET method appends form data to the URL, making it visible to users and limiting the amount of data that can be sent. 

<form method="POST" action="process_form.php">
  <!-- form fields go here -->
  <button type="submit">Submit</button>
</form>
```

```php
<form method="GET" action="process_form.php">
  <!-- form fields go here -->
  <button type="submit">Submit</button>
</form>
