What is the recommended approach for sending an ID through a hidden button in PHP?

To send an ID through a hidden button in PHP, you can use a form with a hidden input field to store the ID value. When the button is clicked, the form will be submitted, and the ID will be sent along with it. This approach allows you to pass the ID securely without exposing it in the URL.

<form method="post" action="process.php">
    <input type="hidden" name="id" value="123">
    <button type="submit">Submit</button>
</form>
