How can checkboxes in a form be properly processed in PHP to avoid data being displayed in the browser URL?

When processing checkboxes in a form in PHP, it is important to use the POST method instead of the GET method to avoid displaying the data in the browser URL. By using the POST method, the data is sent in the HTTP request body rather than as part of the URL. This helps to keep sensitive information secure and prevents it from being easily visible to others. 

<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
    if(isset($_POST['checkbox_name'])) {
        // Process the checked checkbox value here
    }
}
?>
