Is it considered good practice to mix GET and POST data in PHP forms?

It is not considered good practice to mix GET and POST data in PHP forms as it can lead to security vulnerabilities and make the code harder to maintain. It is recommended to stick to either GET or POST for passing data in forms to ensure consistency and security. 

// Example of using only POST data in a PHP form
<form method="post" action="process_form.php">
    <input type="text" name="username">
    <input type="password" name="password">
    <button type="submit">Submit</button>
</form>
