What are the potential drawbacks of using iframes to simulate real-time data updates on a webpage?

Using iframes to simulate real-time data updates on a webpage can lead to slower loading times, potential security vulnerabilities, and difficulties in maintaining and updating the code. To solve this issue, it is recommended to use AJAX (Asynchronous JavaScript and XML) to fetch and display real-time data without the need for iframes. 

// Example PHP code using AJAX to fetch and display real-time data on a webpage

<!DOCTYPE html>
<html>
<head>
    <title>Real-time Data Updates</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <script>
        $(document).ready(function(){
            setInterval(function(){
                $.ajax({
                    url: 'update_data.php',
                    type: 'GET',
                    success: function(data){
                        $('#real-time-data').html(data);
                    }
                });
            }, 5000); // Fetch data every 5 seconds
        });
    </script>
</head>
<body>
    <div id="real-time-data"></div>
</body>
</html>
