What is the best approach to handle user interactions with PHP scripts through HTML buttons?

When handling user interactions with PHP scripts through HTML buttons, the best approach is to use a form with a submit button that sends a request to the PHP script. In the PHP script, you can check for the form submission and process the data accordingly. This allows for a clear separation of logic between the front-end and back-end. 

<form method="post" action="script.php">
    <button type="submit" name="action" value="button1">Button 1</button>
    <button type="submit" name="action" value="button2">Button 2</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['action'])) {
        $action = $_POST['action'];
        
        if ($action == "button1") {
            // Handle button 1 action
        } elseif ($action == "button2") {
            // Handle button 2 action
        }
    }
}
?>
