What are some best practices for handling user interactions, such as clicking on images, in PHP scripts?

When handling user interactions like clicking on images in PHP scripts, it is important to use a combination of HTML and PHP to capture the user's action and process it accordingly. One common approach is to use HTML forms with hidden input fields to pass information about the clicked image to the PHP script. The PHP script can then retrieve this information and perform the necessary actions based on the user's interaction. 

<!-- HTML form with hidden input field to capture image click -->
<form method="post" action="process_image_click.php">
    <input type="hidden" name="image_id" value="123">
    <img src="image.jpg" alt="Image" onclick="this.form.submit()">
</form>

<?php
// process_image_click.php
if(isset($_POST['image_id'])) {
    $image_id = $_POST['image_id'];
    // Perform actions based on the clicked image ID
}
?>
