What are the potential pitfalls of using both GET and POST methods in PHP forms?

Using both GET and POST methods in PHP forms can lead to confusion and potential security vulnerabilities. It is recommended to choose one method based on the specific requirements of the form. If you need to send sensitive data, use POST method for better security. If you need to send non-sensitive data or want to bookmark the form URL, use GET method. 

<form method="post" action="process_form.php">
  <!-- form fields here -->
</form>
