What are the potential drawbacks of using meta refresh tags to reload a page for real-time updates in PHP?

Using meta refresh tags to reload a page for real-time updates in PHP can have several drawbacks. One major issue is that it can negatively impact the user experience by causing the page to constantly refresh, leading to slower loading times and potential frustration for the user. Additionally, it can put unnecessary strain on the server by generating frequent requests for the same content. To solve this issue, it is recommended to use AJAX (Asynchronous JavaScript and XML) to fetch and update data from the server without the need to reload the entire page. This allows for real-time updates without disrupting the user experience or overloading the server.

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

        $(document).ready(function(){
            function fetchData(){
                $.ajax({
                    url: 'update_data.php',
                    type: 'GET',
                    success: function(data){
                        // Update the content on the page with the new data
                        $('#content').html(data);
                    }
                });
            }
            
            // Fetch data every 5 seconds
            setInterval(fetchData, 5000);
        });
    </script>
</head>
<body>
    <div id="content">
