What are the differences between using GET and POST methods in PHP for form submission?

When submitting a form in PHP, the main differences between using the GET and POST methods are how the data is sent and how it is visible to the user. GET sends form data in the URL, making it visible and limited in size, while POST sends data in the HTTP request body, keeping it hidden and allowing for larger amounts of data to be sent securely. 

<form method="post" action="process_form.php">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  <button type="submit">Submit</button>
</form>
