What are the advantages of using POST method over GET method when submitting form data in PHP?

When submitting form data in PHP, using the POST method is preferred over the GET method for several reasons. POST method does not expose sensitive data in the URL, making it more secure. It also allows for larger amounts of data to be submitted and is not limited by the length restrictions of a URL. Additionally, POST method is more appropriate for submitting data that will be processed and stored on the server.

<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">
  
  <input type="submit" value="Submit">
</form>
